Students will learn about the laws of motion and force.
For the class:
For each group:
For each student:
Thanks to Sir Isaac Newton’s research of approximately 360 years ago, we have the laws of motion and force. Those laws have led to many wonderful achievements in science, which have profound impact on our everyday lives. His first law states that objects at rest will remain at rest unless acted upon by an outside force that is great enough to overcome the object’s inertia, or tendency to stay still; the larger the object is, the more force is required to move it.
The activities in this lesson are designed to lead students to understand this concept and to relate it to their everyday lives.
Some classes may need some time built into the lesson to explore the materials before they are ready to handle them appropriately. Some students are extremely sensory-based in their actions and the manner in which they attempt to make sense of their world. If needed, conduct a short, introductory activity to allow the students to handle the materials, showing them how to appropriately use them.
1. Use Science Process and Thinking Skills
2. Manifest Scientific Attitudes and Interests
3. Understand Science Concepts and Principles
4. Communicate Effectively Using Science Language and Reasoning
Invitation to Learn
Bump on a Log
Divide students into groups and place a lump of clay in front of them on the floor or on a group of desks. Use the Bump on a Log handout to connect with the idiomatic phrase, if desired. Instruct them not to touch the clay or try to move it in any way. Have the students discuss and describe it’s action by answering the following questions:
Have students share their observations with the class.
Use the Move It at Home, Sir Isaac! worksheet to compare the force needed to move various objects in the home. Record the results and share with the class (e.g., instead of using a finger to push a small object, what did they use to move a box of cereal? What did they use to move a chair? What would they have to use to move their bed?). Be sure to record the number of hard and soft pushes used and the distance the object was moved.

Learning with understanding must build on what students already know and their ways of thinking. Teachers need to gain understanding of ideas that would enable them to adapt an innovation in teaching practices to their own instructional settings. Instead of thinking of adopting resources and using them as they are presented, teachers need to adapt the resources to the needs of their teaching circumstances.
