View this Bozeman Science Video - Developing and Using Models

• Think about a question that you have about something in and around your home. How could you design an experiment that would answer that question?

Students can now choose to learn more about a related topic by researching it on their own.

Use this Force and Motion Investigation sheet as a guide, if you like. There is a reaction time inquiry on Day 3 for this week that you might want to use for your inquiry. (Design your own reaction time experiment)

Activity 81 - How can you tell if the forces on an object are balanced or unbalanced? (Students have done the PhET activity and learned about this topic in a previous lesson)

• Activity 81 - Labsent video

• Activity 81 - The Net Force Challenge

Activity 82 - How can friction lower the risk of getting into an accident?

• Activity 82 - Labsent video

Activity 82 - Braking Distance Packet

Additional resources you can use for your inquiry

Activity 83 - How does a car’s stopping distance change in different situations?

• Student worksheet for Stopping Distance

• Video - Stopping distance demonstration

• Design your own reaction time experiment

Activity 84 - How can a person’s deceleration be controlled during a collision?

Student worksheet for Decelerating Safely

Additional resources you can use for your inquiry

Activity 86 - How does the center of mass affect what happens in a collision?

• Activity 86 - Labsent video

• Activity 86 - Investigating Center of Mass packet

The Challenge - Find a live animal and observe its characteristics (color, shape, size, etc.). Write about or draw what you notice and any questions you are wondering about what you see why does it look the way it does? What characteristics are helpful?

Materials

• A live animal to observe (try collecting a worm, ant, snail, or other bug from your yard or a nearby park)

• Drawing materials

• Magnifying glass (optional)

More ideas

Compare and contrast your observations and what you notice and wonder.
