1. The teacher will describe the way the balls rolled toward each other, hit each other. Upon impact the balls rolled backwards, demonstrating Newton’s Third Law of Motion.
2. The teacher will state that the Third Law of Motion is “For every action, there is an opposite and equal reaction.” The teacher will ask learners/students to turn and talk about what this Law actually means.
3. The teacher will explain these examples using sequence words.
a. First, the roller coaster will build pressure.
b. Next, it will shoot forward.
c. Then, my body will be pushed back into the seat.
4. The teacher will ask learners/students if they can think of examples found in sports. The teacher will put the learners/students into heterogeneous groups of 3 or 4 and ask them to create an experiment that they could conduct to prove Newton’s Third Law of Motion.
5. The teacher will ask learners/students to briefly explain their experiment using sequence words, such as first, then, last.
6. Students will write the experiment and then present it in appropriate order.
7. The teacher will call on learners/students to explain what they think the law means.
6. The teacher will provide real life examples of the Third Law of Motion, such as when you are in a car and you brake hard, your body moves forward. Another example is on a roller coaster; as the coaster jerks forward, you are pushed back.
