What makes a toy car roll further: a steep hill or a gentle one? Hands up your guess.
Two words for today. A force is a push or a pull that changes how something moves, like the push that sends a toy car. A ramp can also give the car a stronger start down the slope. Compare means we try two versions and notice how the results differ.
Here is our question today: does a higher ramp make a toy car roll further than a lower ramp?
We will change just the height of the ramp, try both heights, and measure how far the car goes. Keep the car and everything else the same.
Say your prediction out loud and one reason why.
Before we use our real ramps, we will practise one quick compare on the board. This practice uses the slope too, just like your real test with the ramps.
Watch the car on the slope. Predict first: will a steeper slope send the car further, or not as far?
When the second run finishes, look at the two stop markers on the tiles. Those markers show how far each run went. What did our change do?
How far will it go?
