Force and Motion Kindergarten Science Lab: Driving Cars

What preschool or kindergartner doesn’t love playing with cars? 
Especially boys!  My 4 year old preschoolers LOVE driving our hot wheels
All. Over. The. House.  So, I knew they would love doing
this force and motion kindergarten science lab
with me this week!  

This is a great science lab for teaching kids about cause and effect, force
and motion, and helping them critically think about what they are doing! 
Plus, this kindergarten OR preschool science experiment is the easiest
prep…  I’m all about simple right now, so I bet you already have
everything you need to do this lab right away!

Materials & Prep

For this force and motion kindergarten science lab, you will need…

To prep this kindergarten OR preschool science experiment, you will need to
tape the colored papers together in rainbow order as a race track.  I
taped mine together on the short edge to make our track longer.

Science Lab Steps

First, we set out the rainbow race track.  My unicorn and rainbow-loving
girl LOVED this part! 🙂

Next, we lined up a car.  I asked, “What do we need to do to race our
car?”  

“PUSH IT!”  

I reinforced, “Yes, we have to push the car if we want it to
move.”  Then, I told one of them to move the car.  

We cheered for the car and then
recorded
how far our car traveled.

Then, I let the other twin have a turn.  And I asked her the same
questions about how to move the car.  We cheered for the car and then
recorded how far our car traveled.  (We used the same car for both kids
so there would be no confusion that maybe one car is faster.)

Again, we cheered for the car and then
recorded
how far our car traveled that time.

Then, I asked, “Which car moved the farthest?  Why do you think it
did?”  I was trying to get them to see that a bigger push moves the car
farther.

Finally, I asked, “What can we do to make this car move even farther?” 
We try one more time and
record
how far our car traveled!

Teaching Points

Once all of the races are finished, we talk together about why are cars moved,
what made them move farther, not as far, etc.  

The main idea I’m trying to get my preschoolers or kindergarteners to
understand is…

An object needs a force in order to move.  OR  An object cannot move without force.

In a kindergarten class,
this force and motion science experiment
can be done whole group, or you can start whole group and then have groups
test out races with partners.  It’s definitely a flexible science
activity for kindergarten or preschool!

You can find this experiment and much more in this
Force and Motion Kindergarten Science unit
that is aligned with the Next Gen Science Standards!
