When it comes to winter, we love snow. It provides inspiration for so many fun kids winter crafts & activities.
We also love heading out for plenty of snowball fights and sledding.
Not only is sledding fun, but with each giggle and grin as the kids fly down the hills, there’s also an opportunity to talk about the science of sledding.
Yep, you can tell I’m a homeschool mom. I use every opportunity to teach the kids, including our time outside sledding. (Shhhhh! My kids think all moms do this.)
When it comes to winter science activities for kids, sledding provides so many fun ways to learn!
Your child will also love this fizzing snow activity.
Physics of Sledding
Sledding is perfect for discussing physics and energy.
As your child sits on their sled at the top of the hill, they have potential energy.
With a push it suddenly changes to kinetic energy as the sled starts to fly down hill.
Sledding is also a wonderful opportunity to talk about Newton’s first law of motion. This simply states that an object at rest will stay at rest unless acted on by an outside force.
This is easy for even very young kids to understand as they sit at the top of the hill, waiting patiently (or not so patiently) and not moving until mom or dad gives them that little push.
I repeated Newton’s law several times for my children as they waited for that push on our last sledding excursion. By then end of the day they were quoting it right back to me.
Newton’s first law also states an object in motion will stay in motion unless acted on by an outside force.
I asked the kids what they thought could make the sled stop. They both mentioned that running into something would make it stop. (One of my son’s favorite ways to stop, no doubt.)
We talked about how the grass poking up from the snow could also affect the sled.
Which brings me to friction.
Sledding is a perfect hands-on opportunity to talk about friction!
They both noticed that the sled stopped faster if it ran over a lot of grass or the rope that was tied to the sled versus just running over the smooth snow. It wasn’t hard for them to figure out that the snow caused less friction than the grass.
You could easily take it a step further and challenge older kids to try to find ways to further reduce friction on the sled.
Could rubbing wax on the bottom of the sled help?
Make Sleds Go Faster
After discussing energy and friction, challenge your child to come up with the best position to sit on the sled to make them go the fastest.
Will the sled go faster if you lay down or if you are sitting up?
The sled will go faster if you cut down on wind resistance by laying down. Now your child is learning about wind resistance, which is another form of friction that occurs when sledding.
Where does the center of your mass need to be on the sled in order for it to go the fastest? (In other words, where should the majority of your body be on the sled?)
What else can they do in order to make the sled go faster?
The next time you have snow, be sure to check out some of the science of sledding with the kids.
