Objective

By the end of this lesson, the student will be able to understand the basic principles of physics related to trucks and apply them to real-life situations.

Materials and Prep

• Toy trucks (at least two different types)
• A ramp or inclined surface
• A stopwatch or timer
• A measuring tape or ruler

Prior knowledge required: Basic understanding of colors, shapes, and counting.

Activities

1. Explore the concept of gravity and motion:

   • Place the toy trucks at the top of the ramp and let them roll down. Observe how gravity pulls the trucks downwards.
   • Discuss how the trucks move faster or slower depending on the steepness of the ramp.
   • Encourage the student to experiment with different surfaces and angles to see how they affect the truck's speed and distance traveled.

2. Introduce the concept of force:

   • Ask the student to push the toy trucks on a flat surface and observe how they move.
   • Explain that pushing the truck applies a force, which makes it move.
   • Discuss how the force applied affects the speed and direction of the truck.

3. Measure and compare distances:

   • Using the measuring tape or ruler, measure the distance each truck travels when rolled down the ramp from the same starting point.
   • Compare the distances traveled by the different trucks and discuss why one may have gone farther than the other.
   • Encourage the student to come up with hypotheses and explanations for the differences observed.

Preschool Grade Talking Points

• "Trucks can move because of something called gravity. Gravity pulls things down to the ground."
• "When the ramp is steeper, the truck goes faster. When it's less steep, the truck goes slower."
• "When we push the truck, we use our muscles to apply a force. The force makes the truck move."
• "We can measure how far the truck goes by using a measuring tape or ruler. We compare the distances to see which truck went farther."
