Science - 1st Grade
Standard 3 Objective 1
1 class periods of 60 minutes each
Students learn that every force is either a push or a pull. They push and pull objects in the classroom. Students use a rubber ball to demonstrate motion words such as: straight, zigzag, curved, back-and-forth etc. Raising a ramp a ball is rolled down from demonstrates the principle that increasing force increases the distance an object moves.
The movement of objects is caused by a force that is either a push or a pull. When an object moves there is an interaction between two objects resulting in a force. How an object moves by one of these forces depends on a number of factors: size, weight, shape, and the degree of friction. When an object moves it can move along different paths. Words we use to describe this movement can be demonstrated in the lab using a rubber ball.
Increasing the force on an object can increase its movement. When a ball is released down a ramp from increasing heights, the force on the ball increases. The larger the force on the ball, the farther it will move.
Pre-lab Discussion: Show students a basketball and ask how they make it move. Wait for a student to say it needs to be pushed. Discuss with the students the push from your arm, which moves the ball towards a basket. Ask the students to act out several other movements: raise your hand, lower your hand, clap your hands, and push your seat back. Explain to the students that all movements are either a push or pull and that is what they will be exploring today.
