• Systems and System Models
• Stability & Change

### Task #1  – (40 Minutes)

Today is the day! Each team has built a mousetrap car. Each team has test driven their cars and then taken them home to make modifications to them. This is our day to run our final experiment and do our write up. Each team member has a fresh copy of their mousetrap data chart and directions on how to do their write up after the final experiments have been run.

Car Testing Experiment – 20 Minutes

### Task #3 – Reintroduction to Sound Waves (D.O.K. 2 – Application of Knowledge – How is it used?) (20 Minutes)

Socrative.com Quiz – We are now going to go to Socrative.com and take a quiz using our new note sheet.  Room – “A89559b4”

### Task #4 – Reintroduction to Sound Waves (D.O.K. 3 –  Strategic Thinking – Why/How is it used?)

Now that you have gone over the introduction notes on sound and taken a comprehension quiz on the information you and your group will be designing an experiment to prove the existence/behavior of a sound wave. Since it has been awhile since we have talked about how to set up an experiment I want us to do a quick reminder activity. I will have a physical copy of the PDF file below to give to you.

### Task #5 – Reintroduction to Sound Waves (D.O.K. 4 – Extended Thinking – What impact/Influence?)

What are three reasons why humanity should study waves?

### Next Generation Science Standards:

HS-PS 2-6 Communicate scientific and technical information about why the molecular level structure is important in the functioning of designed materials.

HS-PS 3-3 Design, build, and refine a device that works within given constraints to convert one form of energy to another form of energy.

HS-PS 4-1 Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
