View Bozeman science video Cause and Effect.

Look at objects that can be moved in your house.

• Define the system that affects the movement of the object. For example, if you roll a ball across the floor, these components of the system will change how it moves:

  • The balls material(rubber ball versus marble)

  • The shape of the ball (football versus soccer ball)

  • the type of floor that it is rolling on (carpet, hardwood, cement)

  • The slope of the floor (is it level or at an angle)

  • Is a force needed for the object to move or does it move by itself?

• What are the boundaries of the system of the moving object? (What is in the system and what is not in the system?)

• Draw your moving object. Label the parts of the system. Then describe how the different parts of the system interact.

This week and next we will learn about waves, specifically sound waves and light waves.

Introduction: Play around with this simulation, Waves Intro. You will investigate water, sound, and light. (Be sure to use the graph options when you can, and try out all the features in each section.)

• As you investigate what can you figure out about characteristics of waves?

• What is amplitude?

• What is frequency?

• Where and how is energy being transferred? Where do you think you see cause and effect in waves? What questions do you have about waves?

Next, investigate waves further with this simulation, Waves on a String.

• Where and how is energy being transferred? Where do you think you see cause and effect in waves?

Try this STEAMSquad activity set, Eavesdropping on Animals.

• To use this set, watch the intro video, then work your way through the activities. Definitely try the intro, #1, #2, and #5 before trying the citizen science project.

What did you learn this week about waves?

Use this graphic organizer to share one example of cause and effect for something that you learned this week.

Materials: paper (Newspaper, junk mail, index cards, etc.) 2 feet of tape.

Challenge: Using only the materials from the list above, create a freestanding structure that is at least one foot high and can hold a small stuffed animal or toy.

Think about it:

• What are some strong shapes that you can see in bridges or towers?

• Could you combine the tape and paper to make a stronger material?

• What’s the most important use of your tape?

• After you test: If you did this again, what would you do differently?

Use the Engineering Design Process to build your structure:

• Define: What is it that needs to be accomplished?

• Brainstorm: What are your ideas for meeting the criteria of the challenge?

• Plan: Draw and discuss your design.

• Make It! and then Test It!

Improve: Make it better by repeating the Engineering Design Process again!
