Students will answer this question before leaving class today.

Behavioral Norms:

  • Learn from mistakes
  • Tolerance
  • Participate
  • Personal electronics only when appropriate

Key Concepts:

  • Definition of Energy

Warm Up:

What does your name mean?

Using a dictionary, google or any other resource, I want you to find and write down an appropriate adjective that begins with each letter of your first name. For example:

Factual, Relaxed, Extrovert, Determined


Task #1 – Review of Unit 6 Key Concepts (40 minutes)

You have probably noticed by now that your desks are arranged by teams. This is going to play an important role throughout today. I want to go back through some key concepts before we move on to Unit 7, just to make sure that we understand them. These concepts will be playing an important role in our next project.



Review Concept #1 – Speed, Velocity, Acceleration, & Force (20 minutes)

Papers will be handed out to each team. On these papers will be the formulas we need, some problems to solve, and important vocabulary to remember. As a team, using the resources at your disposal, you will have 15 minutes to solve these problems before turning them in. You will not have a chance to change your answers once you turn your papers in.

PDF Copy -> *will be added after today’s lesson*



Review Concept #2 – Distance vs Time Graphs (15 minutes)

Take a look at the graph below. What story could be associated with this graph? That is up to your group to decide! For this review concept you will need to show your group understands how to read this graph and convey a story about it using 5 of the vocabulary words from the word pool that is also located below.

Review Concept #2 Graph

Review Concept #2 Word Pool

  1. Constant speed – Speed that does not change
  2. Velocity – Speed in a given direction
  3. Frame of reference – A background used to judge motion or speed
  4. Instantaneous Speed – Speed at a given moment in time
  5. Speed – amount of distance traveled in a certain amount of time
  6. Average Speed – total distance divided by total time
  7. Time-Distance Graph – graph that shows speed of an object
  8. Acceleration – change in velocity over time
  9. Motion – an object changing position or distance in time
  10. Rate of Change – amount of time it takes to change position or motion


Review Concept #3 Action vs Reaction Forces (5 minutes)

Each member of your team will receive a blank piece of copy paper. On this paper you will put your name in the top right corner. You will be able to use this entire piece of paper. On the paper you will draw a picture and label the action vs reaction forces with arrows that are taking effect in the picture as well as any friction that may be present. Use the example below for an idea. Fair warning: no you can’t draw the picture below. If you do you will not receive credit.

Action vs Reaction Forces Example:


Task #2 – (Introduction to Work, Power, and Machines) (15 minutes)

I will be giving you a physical copy of the notes located below.  This will be our first time getting ready for Unit 7.

Task #3 – Comprehension Check (10 minutes)

Think we got it in theory? Lets test it. I am going to give your group a simple comprehension check. Use your notes and peers to answer the questions to the best of your ability. On the computer in your group.

Go to and enter room “A89559b4”


Task #4 – Unit 7 Project Introduction (10 minutes)

Remember our balloon cars from the last unit? This unit is going to get a bit more complicated. Your teams will be designing mouse trap cars. In this task I will be going over the rules for the build time, type of construction, etc.


Task #5 – Unit 7 Project Research & Design (15 minutes)

With the basic idea of how a mousetrap car works your team will now use a laptop, smartphones, etc to sketch out an idea of how you should build your mousetrap car. Before you leave today you will need to turn in a design sketch and list of materials being used in the build design.


Ticket Out the Door:

Sticky note questions

#1 – What is the number one thing you learned today?

#2 – What was the most confusing thing you did today?



Review what we went over today. Begin thinking about how your team wants to assemble your cars.


Next Generation Science Standards:

HS-PS 3-1

Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other components and energy flows in and out of the system are known.

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.
