In this video, Jeff viniker explores patterns of motion and friction. Motion is the process of an object moving or being moved. It can be straight, circular, up and down, zig ziggy, or side to side. It can also be a combination of up and down or forward and backward.
Have you ever wondered how does friction affect the speed of a car? A car’s speed is often determined by the friction between its wheels and the road. Jeff demonstrates this phenomenon with a very simple experiment. The key to this experiment is car friction, or resistance created, between the car’s wheels and the track. Try it at home and learn it first hand.
This video satisfies the 3-PS2-2 requirement for third-grade science proficiency.
Students who demonstrate understanding can:
3-PS2-2. Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.
