ENGAGE: The class will review the movement of objects recorded on the chart during Day 1: "Move It!" lesson. Any misconceptions or areas that were confusing not addressed in Day 1 should be discussed now.
The students will brainstorm opposite movement that results in motion, such as walk/run, open/close, push/pull.
EXPLORE: Students will locate objects in the classroom that push or pull or need to be pushed or pulled to be used. They will perform those actions with classroom objects and record findings in their science notebook. The teacher will question, observe, and record student thoughts on the Student Observations of Movement of Objects sheet, available for download in Attachments.
Students will come back together. Through discussion as a group complete a push/pull Venn Diagram, available for download in the Attachments.
EXPLAIN: Students will work together as a whole group to create definitions of push and pull. The book, Give it a Push! Give it a Pull! by Jennifer Boothroyd will be read to the class. The class definitions will be compared with ones presented in the book.
ELABORATE: Students will go outdoors to practice pushing and pulling with objects on the playground, such as doing pull-ups or push-ups. Students will answer the questions:
- Can pushes and pulls can have different strengths and directions?
- Can Pushing or pulling on an object change the speed or direction of its motion or can start or stop it?
- When objects touch or collide, will they push on one another and change motion?
- What happens when there is a bigger push or pull?Will the objects speed up or slow down more quickly?
