Grade 8 Unit 1: Contact Forces + Computer Science
Why does contact between things sometimes cause damage, and how can we protect against it?

We want to hear from you! If you want to get in touch with the OpenSciEd Field Test community while you are teaching or preparing to teach, please use the Facebook group. To share ideas about what worked well or what we should change in a specific lesson after you teach it, please send us your feedback using the Unit 8.1 Open Feedback Form.
Lesson Question: How much do you have to push on any object to get it to deform (temporarily vs. permanently)?
Lesson Question: Where would more reliable force measurement devices help us better understand/explain phenomena and design solutions to problems?
Lesson Question: Where did the energy in our launcher system come from, and after the collisions where did it go to?
Lesson Question: How could detecting the force of the wind help us prepare for and prevent potential damage from severe storms?
Lesson Question: How does building and (re)testing a prototype of our designs help us refine our design proposals?
Lesson Question: How do the force interactions on the objects in contact and in a collision compare?
Lesson Question: What inputs can different sensors detect and how can we repurpose them to respond to changes in the force applied to a system?
Lesson Question: How do other contact forces from interactions with the air and the track cause energy transfers in the launcher system?
Lesson Question: How does the micro:bit computer know what output to provide for different input conditions from different sensors?
Lesson Question: How much does doubling the speed or doubling the mass affect the kinetic energy of an object?
​
Lesson Question: Why do some objects break or not break in a collision? And, how can sensors help prevent collisions?
Lesson Question: What criteria should we use to evaluate all the different design solutions we want to build, test, and refine?​
