Kindergartners are looking for more ways to change the motion of a car.  They've already changed the height of the ramp.  Now they're keeping the ramp height the same and changing the weight of each car they test.

Using measurement skills, students determined how far the car went and compared it to the results from each test they did.  Check out their work to the left...this chart shows that as the weight of the car increases, so does the distance it travels!  The opposite can also be true.  As the weight of the car decreases, the distance it travels becomes less.

I wonder what would happen if we increased the weight of the car to more than 10 weights!  What do you think?

Kindergartners know that forces can be pushes and pulls and that they can vary in strength and direction.  But how can they use all this knowledge to change the motion of a toy car?

Here are all the materials they have:
1.  A toy car
2.  A ramp
3.  Three wooden blocks

Students figured out that they could raise the ramp with the three blocks.  Many students  hypothesized that they car would go farther or faster by raising the ramp higher.  But there would be only one way to figure out if their hypotheses were correct.

"A TEST, MRS. BRINZA!!!  LET'S TEST IT!"


Students are collecting evidence to support their hypotheses using string to measure the distance the car travels on ramps of 1 block, 2 blocks, or 3 blocks high.  Check back soon to see our results!

Kindergartners continue to work on modeling.  Models not only show a phenomena, but they also explain why something happens.  As we dig deeper into understanding the effects of forces, Kindergartners paused to make certain they understood HOW to compare things.  Before we step into designing an investigation that compares forces, it's important that we know how to compare if something went far, farther, or the farthest.  Check out our introductory lesson on comparison words!

STRAIGHT!  BACK-and-FORTH!  Or in a CIRCULAR motion!

Using everyday toys, Kindergartners are seeing how their varying forces can change the direction in which different objects move.  Some students said, 

"The path looks like a zig-zag!"
"It keeps going around and around!"
"This is boring motion.  It only moves straight.  :("

They'll be using all this knowledge to solve some problems related to motion!  Keep up the great work Kindergartners!
