Newton's Third Law Of Motion

Optional: have students write down the terms and definitions in their science notebook.
Introduce Newton's third law of motion.
• Newton's third law of motion - For every action there is an equal and opposite re-action.
Have students read pages 160,161 in their class books. Then have students complete page 119, activity 9,10 in their workbooks.
The teacher will provide feedback to the students throughout the lesson by asking probing questions to guide students in understanding the concepts of the lesson. Questions such as these can be used to assist students:
▪ How have you been able to move an object?
▪ In what ways could you make a wagon move?
▪ Explain what would happen if you kicked a ball.
Teacher circulates around the classroom. The teacher will provide feedback individually as student's complete independent practice.
The teacher will pose the following two scenarios. Write them on the board.
▪

Student's responses should be written illustrating complete thoughts while incorporating the vocabulary terms for this lesson. Remind students to include examples and specific details in their answers.
Guiding questions for this lesson?
▪ How does Newton's third law of motion explain how forces move objects?
▪ How can you use Newton's third law of motion to explain what happens when a force is applied to an object but it does not move?
Give an example of Newton's third law of motion where forces are equal. (Example answer: Sitting on a chair, computer sitting on a desk)
Closure:
▪ Now, provide time for students to put their understanding of Newton's Third Law of Motion to the test. Put students into pairs. Allow the pairs 10 - 15 minutes to brainstorm a real life example of Newton's Third Law of Motion. Student pairs should be encouraged to be creative in choosing their examples and should not be any of the same already
