Sound: Engineering a Concert Grade 1

Our Vision of Elementary School Science Excellence

Success Academy’s unique commitment to science starts in kindergarten. We strive to cultivate a passion for the sciences early in life, build a comprehensive foundation of knowledge, and teach students to investigate and analyze real-world problems. Our vision of science relies on two related commitments: mastery of a substantive body of scientific knowledge and an inquiry-based approach to accumulating this knowledge. Equipping students with a firm grasp of scientific concepts is central to our model, and students must understand that these concepts aren’t simply plucked from the air, but rather arrived at through scientific thinking and experimentation. To that end, our scholars do science to understand that scientific knowledge comes from posing questions, designing experiments, gathering data, and drawing conclusions. Rather than viewing scientific knowledge as etched in stone, they come to understand that ideas about the world change with new evidence. In addition, our program incorporates The Next Generation Science Standards (NGSS) and the BSCS 5E Instructional Model.

We believe excellent science classrooms are ones in which students experience curiosity and joy, and make connections between classroom science and the natural world around them. Embedded in our program is the belief that struggle and student-led inquiry are inherent to the mastery process. Through our progressive approach to learning, students realize that unexpected results do not signal failure, but instead present valuable opportunities for new questions.

Through our science program, students learn that science and engineering are creative and exciting fields. They discover that there are countless, fascinating scientific questions to be asked and engineering challenges to be solved—and will be inspired and equipped to seek out answers and solutions. No matter what path students choose to pursue in life, the SA science program will spark curiosity, sharpen problem-solving capabilities, and fuel passion for knowledge.

Essential Questions

The best questions point to and highlight the big ideas. They serve as doorways through which learners explore the key concepts, themes, theories, issues, and problems that reside within the content, perhaps as yet unseen: it is through the process of actively “interrogating” the content through provocative questions that students deepen their understanding.1

Use the essential question to drive the unveiling and mastery of ideas, and ground the unit in an overarching purpose, often as a storyline. Mentioning the essential question or having students answer it at the end of some lessons does not mean the teacher is using it purposefully.

Purpose: The Why, What, and How of This Unit

Essential Question:

How can humans use sound to create an outstanding concert?

Why This Unit?

Your lab is hosting a Science Concert, and your scholars will be the stars! In this unit, scholars will dive headfirst into the world of sound waves, exploring their characteristics and the ways that humans detect waves to better understand the world around them. Scholars will investigate the nature of sound waves and use their observations to make meaning of the relationship between vibrations, waves, and sounds. Can scholars use these discoveries to create their own instrument in time for your lab’s Science Concert?

What is the bottom line?

Science and Engineering Concepts highlighted in this unit:

  • Big Idea: Vibrating matter can create sounds, and sounds are created by vibrating matter.
  • Big Idea: Waves, created by regular patterns of motion, can be detected by humans to help them better understand the world.

Science and Engineering Practices highlighted in this unit:

  • Develop and Use Models
    • Distinguishing between a model and the actual object, process, and/or events the model represents.
  • Analyze and Interpret Data
    • Using observations to describe patterns and relationships in order to answer scientific questions and solve problems.

Note: As with any unit, scholars engage in many practices in a given investigation. These practices are highlighted because they appear in most lessons.

How will scholars be assessed?

  • Teachers are expected to give scholars grades for every unit. Use the materials throughout this guide to assess scholar mastery.

Safety

Plan carefully for safety in all lessons. The top safety risks in this unit include:

  • Exercise caution when using rubber bands; ensure scholars understand expectations for safe use.
  • Scissors may present a safety hazard.

    • Ask the scholar not only to repeat the process but also to strike the tuning fork on a hard surface before moving it near the Ping-Pong ball.
      • What does this model prove about sound vibrations?

Accountability (Informal)

Use scholar conversation and scholar work to determine how well scholars understand the Big Science Idea: Repeated patterns of motion create waves. By the end of this lesson, scholars must know that a vibrating object can create a wave. They should observe the effect of vibrating a Slinky: a wave. In the next lesson, scholars will have one more opportunity to understand that vibrating matter creates waves. Consider which students will need additional support with this concept.

Lesson 4: Making Waves

Scholars have unearthed the secret behind vibrating Slinkys, but what do all vibrating objects have in common? Today, scholars explore more vibration models in order to prepare for the upcoming Sound Experts presentation.

Lesson Objectives

  • Big Science Idea: All vibrating matter creates a wave.
    • Key Takeaways:
      • Waves are created when matter vibrates.

  • For each table: clear water bin, deli tray lids, thin rope, ribbon

Prep

  • Fill each bin ⅓ full with water.
  • Tie one end of the rope to the bottom of one table leg at each table.

Launch

  • You have used the Slinky as a model, but now, we must understand what all vibrating objects have in common. We know that vibrations and sound are connected, so it is important we understand what vibrating objects do!
  • Scientists use multiple models to understand what they observe.
    • Show scholars a picture of an animal skeleton model and show an additional picture of a different model of the same animal.
      • Why would a scientist use both these models to study a horse?
  • Present the lesson challenge:
    • Use different models to determine what all waves have in common. Choose which models the Sound Experts should use to explain waves at the Science Concert.

Activity

  • Scholars work together in partners to explore the different wave models at their table and determine what waves have in common and what they teach us about vibrations.
  • Circulate to look for scholars who are recording their noticings in their lab notebooks. Press them to explain how each model helps them understand more about waves.
  • Procedure:
    • Activity 1: Partner 1 sits on the floor and vibrates the rope tied to the table leg back and forth on the floor while Partner 2 observes the wave.
      • Partners switch roles and then record their observations in their lab notebooks.
    • Activity 2: Partner 1 vibrates the water in the bin by quickly and repeatedly dipping the deli tray lid (or other wide, flat object) into the water. Partner 2 observes the waves overhead and at water level.
      • Partners switch roles and then record their observations in their lab notebooks.

    • What do you predict will happen when I start to spin the handle connected to the wheel?
    • Play music box for scholars under the document camera.
      • What happened when the keys reached a bump on the handle?
    • Revisit the anchor chart listening to audience questions for the Science Concert and add new information.

Accountability (Exit Ticket)

This Exit Ticket assesses scholars’ understanding of the lesson’s Big Science Idea. Vibrating matter can create sounds, and sounds are created by vibrating matter. By the end of the lesson, scholars must know that regular patterns of motion always create waves and the vibrating matter will produce a wave. This is the last lesson that directly addresses this idea. If scholars are still struggling to articulate how sound is created, consider planning a flex lesson, allowing scholars additional opportunities to master this idea.

Assignment:
Put an X next to each activity that makes a wave. [2]

    • What would happen if any tiny water molecules were vibrating? Define molecule.
  • Present the lesson challenge:
    • Explore a model to determine the answer to another audience question, “What happens to molecules inside a wave?”

[Instructional Tip: Explicitly explain the model scholars will be using. They should know that the objects in the water represent molecules, and scholars will be creating vibrations in the water.]

Activity

  • Scholars work together in groups to explore the wave model at their table and determine how molecules behave in a wave.
  • Circulate to look for scholars who are recording their noticings in their lab notebooks. Press them to explain how the object in the water helps them understand what happens to molecules inside a wave and how they know. Look for scholars who are showing the movement in their drawings.
  • Procedure:
    • One scholar places the cork inside one end of the water bin.
    • One scholar vibrates the other end of the water bin by quickly and gently moving the deli tray lid up and down inside the water, discussing and recording their observations in their lab notebooks.
    • Scholars repeat the process with a different material (rubber duck).
    • Scholars discuss what each part of their model (moving deli tray lid, objects in water) represents and how their water wave model shows how all molecules in all waves behave.

Discourse

  • Debrief activity:
    • What happened to the objects in the water bin when the waves moved through them? Why do you think that happened?
    • How does this model help us understand how other waves work?
  • Draw a wave on the classroom easel. Draw three small circles at the beginning of the wave and explain to scholars that the three circles represent three water molecules. Define molecule.

    • Do you agree or disagree with that idea?
    • Why do you think that?
  • Make broader connections: Show scholars a video of the world’s largest crowd wave.
    • What do the people in this model represent?

Accountability (Informal)

Use scholar work and conversation to assess how well scholars understand the Big Science Idea: Waves have predictable motion. By the end of the lesson, scholars must understand that when waves move across the surface of deep water, the water goes up and down in place and does not move in the direction of the wave, as indicated by the floating materials in the bin.

 

Lesson 6: Seeing Sound

Scholars deeply studied the patterns among vibrating objects, but what about vibrations you can’t see? Today, scholars return back to sound vibrations and explore ways to make the invisible visible.

    • Explore the connection between sounds and molecule movements. Search for evidence that sounds move in waves through the air for the Sound Experts to use during the Science Concert.

[Content Tip: Scholars may struggle to make the connection between invisible sound waves and their effect on small bits of matter. If time permits, consider conducting this extra experiment with your scholars that proves the existence of air before teaching Lesson 6.]

Activity

  • Circulate to look for scholars who are recording their noticings in their lab notebooks. Press them to explain the relationship between sound and the movement of salt.
  • Procedure:
    • Scholars sprinkle salt (or other similarly sized particles) on top of the large cup covered in plastic wrap.
    • Scholars hold the pan and spoon in the air near the large cup and hit the pan with the spoon.
    • Scholars observe and record what happens to the salt when a sound is made.
    • Scholars discuss how sound moves through the air and how they know.

Discourse

  • Debrief activity:
    • How did you make a sound with the pan and spoon?
    • What happened to the salt when you hit the pan with the spoon?
    • What is your evidence that the sound is moving in a wave?
  • Make broader connections: Show scholars a picture of a bubble.
    • Ask scholars to predict what might happen if they make a sound near the bubble.
    • Blow a bubble for scholars. Clap near the bubble, which will cause it to pop.
      • Why did the bubble pop when I clapped?

By the end of this lesson, scholars must know that sound travels in waves through air, comparable to waves traveling in water. They will see this as they observe the salt “jumping” when they bang on the metal tray. Note scholars that struggle to articulate the relationship between sound waves and their effect on small bits of matter. Consider how you can support these scholars in upcoming lessons.

Lesson 7: Detecting Different Sounds

The Sound Experts’ problem has been solved, and the wave presentation is being finalized! Scholars will now extend their knowledge of sound to determine different sounds they can create in order to perform the most exciting concert possible for their audience.

Lesson Objectives

Prep

  • Place the penny inside a balloon, inflate, and tie. Repeat the process with a hex nut and the second balloon. Keep an extra penny and hex nut available, so scholars can observe the differences in their shapes, sizes, etc.
  • Place beads inside each deli tray and close the lid. Consider taping the lid shut to prevent accidental spills.
  • Stretch three different rubber bands over the open deli tray. Consider securing the rubber bands by taping them to the bottom of the tray.

Launch

  • Show scholars a picture of a child covering their ears.
    • Why would this child cover his ears?
    • What sense is he protecting?
  • Present the lesson challenge:
    • Create sounds to answer the next audience question, “What are the different kinds of sound that humans can detect?” Use your senses to detect patterns between different kinds of sounds.

Activity

  • Circulate to look for scholars who are collaborating to complete each activity and recording their data accurately in their lab notebook. Press scholars to explain what senses they use to detect each sound and the patterns they notice between the different sounds.
  • Procedure:
    • Activity 1: Scholars take turns tapping the bead drum gently with their pencil and then discuss and record the kind of sound they heard.
    • Activity 2: Scholars take turns tapping the bead drum hard with their pencil and then discuss and record the kind of sound they heard.
    • Activity 3: Scholars take turns shaking the film canister gently and then discuss and record the kind of sound they heard.
    • Activity 4: Scholars take turns shaking the film canister hard and then discuss and record the kind of sound they heard.
    • Activity 5: Scholars take turns plucking each rubber band stretched over the deli tray and then discuss and record the different sounds they heard.
    • Scholars discuss all the ways they can describe each sound and the patterns they noticed between the different sounds.

Discourse

  • Debrief activity:
    • How would you describe the different sounds you detected?
    • What patterns did you notice about the different sounds?
    • Can you think of other sounds that follow the same pattern?
      • [Instructional Tip: Ask scholars to think of other sounds that follow the same pattern that they notice. For example, if scholars notice that sounds become louder when you hit the material harder, prompt scholars to think about clapping as a way to continue the pattern.]
  • Make connections to the essential question: What type of sounds will be best for the Science Concert? How can we make these sounds?
  • Make broader connections: Show scholars a picture of a penny and a hex nut under the projector. Explain that you placed each of these objects in different balloons and are curious what kind of sounds they’ll make when you spin the balloon.
    • Hold the balloon with the penny inside upside down in the palm of your hand and spin the balloon in a rapid circular motion. Repeat the process with the hex nut balloon.
      • What patterns did you notice about the two sounds?
    • Add any new words that describe the sound to the anchor chart created during the discussion.

Accountability (Exit Ticket)

This Exit Ticket assesses scholars’ understanding of the lesson’s Big Science Idea. In this lesson, scholars should notice patterns while exploring at the table. Scholars do not need to know that sounds can have different pitches and volumes.

Prep

  • Print and cut out enough pictures of different sounds for each group.

Launch

  • Play a sound of a baby crying.
    • How would you describe this sound?
    • Why would a baby cry? Define communicate.
  • Present the lesson challenge:
    • Sort different sounds into groups based on what they have in common. Discuss what kind of sounds the Sound Experts should use during their presentation so that they can communicate to everyone in the audience, even if they are far away.

Activity

  • Circulate to look for scholars that are collaborating while they sort. Press scholars to explain how they sorted their objects and identify similarities and differences between each group they created.
    • [Materials Tip: The pictures should show sounds with different volumes and pitches. Consider adding pictures to represent different kinds of sounds based on the way that scholars described sounds.]
  • Procedure:
    • Scholars sort the pictures into groups based on their similarities and record their sort in their lab notebook.
    • Scholars discuss what kind of sound will be able to communicate information to the audience and why.

Discourse

  • Debrief activity:
    • How did you sort the sound pictures?
    • What does each group of sounds have in common?
    • Can you sort these pictures in more than one way?
  • Make connections to the essential question: What kind of sound should the Sound Experts use to communicate what they’ve learned to the audience?
  • Make broader connections: Show the scholars’ individual sound pictures they used to sort with during the activity.
    • What kind of information is this sound communicating to you?

Lesson 9: Engineering an Instrument: Design

The opening night of the Science Concert is just a few short days away! Can scholars put together all of their knowledge about vibrations, waves, and sound in order to create their concert instrument?

Lesson Objectives

  • Big Science Idea: Humans create and use tools to communicate over long distances.
    • Key Takeaways:
      • Tools (e.g., instruments) can be used to communicate information to others over long distances.
      • Different models can be used to solve the same problem. These models have at least some similarities.
  • Science and Engineering Practice: Develop and Use Models Scholars engage in this Science and Engineering Practice as they use models to understand scientific phenomena.

Materials Needed

  • For each table: engineering materials (suggested materials: cardboard tubes, beads, rubber bands of different sizes, empty boxes and containers of different sizes [cups, tissue box, deli trays], straws, film canisters, Ziploc bag, tape, scissors)

Launch

  • Show scholars a picture of a large empty concert hall and a microphone.
    • What are some challenges our team will face if the Science Concert was in this room?
    • What tool do you see that could help you communicate to the people in the very back of the audience?
  • Present the lesson challenge:
    • Brainstorm ideas for an instrument that can communicate soft and loud sounds to the audience, using the materials provided. Choose one instrument to create and begin building your instrument as a team.

[Instructional Tip: Lessons 9 and 10 can be structured in multiple ways. This lesson and lab notebook is currently written to challenge scholars to create an instrument that creates loud sounds and soft sounds. Based on your class’s progress, consider altering the constraints by eliminating this requirement or add constraints based on the types of sounds your scholars have noticed during the previous two lessons (e.g., medium sounds, high and low sounds).]

Activity

  • Scholars work together as a table half to design and begin building an instrument that will play loud and soft sounds during the Science Concert.
  • Circulate to look for scholars who can explain how their team’s chosen design will make loud and soft sounds. Choose scholars to share their designs during Discourse.
  • Procedure:
    • Scholars brainstorm ideas for their instrument using the materials provided and record their ideas in their lab notebook.
    • Scholars select a final design for their instrument and begin to build their instrument together.

[Instructional Tip: Consider showing scholars pictures of homemade instruments if scholars are having difficulties brainstorming ways to create an instrument with the provided materials.]

Discourse

  • Debrief activity: Show two scholar designs.
    • Why did you choose these materials to create your instrument?
    • How will you make sure that everyone in the audience can hear your instrument?
    • How can you make your instrument make loud and soft sounds?
  • Make connections to the essential question: How did you design an instrument to use in the outstanding Science Concert?

Accountability (Informal)

Use conversations and scholar work to assess how well scholars understand the lesson’s Big Science Idea: Humans create tools to communicate over long distances. Scholar work should reflect two different volumes. If scholars are struggling with this idea, consider how you can support them in the final lesson.

Lesson 10: Engineering an Instrument: Build

Scholars have worked hard and prepared diligently for the Science Concert. They will finally use their plans to create an instrument that can create both loud and soft sounds for the performance.

Lesson Objectives

  • Big Science Idea: Humans create and use tools to communicate over long distances.
    • Key Takeaways:
      • Tools (e.g., instruments) can be used to communicate information to others over long distances.
      • Different models can be used to solve the same problem. These models have at least some similarities.
  • Science and Engineering Practice: Develop and Use Models Scholars engage in this Science and Engineering Practice as they use models to understand scientific phenomena.

Materials Needed

  • For each table: engineering materials (suggested materials: cardboard tubes, beads, rubber bands of different sizes, empty boxes and containers of different sizes [cups, tissue box, deli trays], straws, film canisters, Ziploc bag, tape, scissors)

Launch

  • Ask scholars to raise their hand if they have a family member or a friend that they communicate with that lives far away.
    • How do you communicate with them if you can’t travel all the way to their house?
  • Present the lesson challenge:
    • Complete your instrument model started in the previous class. Play your instrument in the Science Concert.

Activity

  • Scholars work together as a half-table group to finish building an invention that will play loud and soft sounds during the Science Concert.
  • Circulate to look for scholars who can explain how their team’s chosen design will make loud and soft sounds. Choose scholars to share their instruments with the whole class during the Activity.
  • Procedure:
    • Scholars finish building their instruments using the materials they selected the previous day.
    • Scholars test their instruments to see if they can make loud and soft sounds.
    • Scholars discuss ways to improve their instrument and record in their Lab Notebooks.

[Content Tip: If time permits, consider extending the engineering lessons by asking each table to create a small presentation that answers one of the audience questions throughout the unit. Scholars can answer these questions during the Science Concert if you’re choosing to invite others to the event. Alternatively, you can film scholars’ presentations.]

Discourse

  • Debrief activity: Showcase scholar instruments.
    • How will you play your instrument so that everyone in the audience can hear it?
    • How does your instrument make loud and soft sounds?
    • What could you do to make your instrument even better?
  • Make connections to the essential question: How did you design an instrument to use in the outstanding Science Concert?
  • Make broader connections:
    • Show scholars a picture of a telegraph. Briefly explain to scholars that telegraphs were invented before telephones were invented and that the telegraph could only make one beeping sound.
    • Show scholars a picture of the Morse code alphabet and briefly explain what the dots and dashes mean.
      • How did people use this tool to communicate without using their voices?

Accountability (Informal)

Use conversations, scholar designs, and scholar revision ideas to assess how well scholars understand the lesson’s Big Science Idea: Humans create tools to communicate over long distances. Scholar work should reflect two different volumes. If time allows, plan a flex lesson where scholars get to make revisions to their designs. Consider how you can support scholars who struggle to articulate that humans create tools to communicate over long distances and support them in incorporating this idea into their instrument.
