Winter Stem Challenges & Forces Lessons For Grades K-5

The Pinterest board is failing to contain the classroom energy. Indoor recess is a slow-motion crash coming for your lesson plan. When the winter weather traps everyone inside, stop fighting the energy and channel it into STEM engineering challenges that actually meet standards.

Start Here: The Misconception That Ruins Everything

Ask your students why a heavy sled moves slower than a light one on flat ground. Write down what they say.

90% of them will tell you “heavy things are just harder to move.” They’re wrong—and if you don’t surface this belief before teaching, it’ll still be there in June.

Here’s the fact that makes them pay attention: An object in motion stays in motion unless something stops it. Try telling a kid that if we were on a giant ice rink in space, their kicked soccer ball would literally never stop. In the classroom, “invisible” forces like friction and air resistance are the “villains” that ruin their engineering designs.

That’s the whole thing. Everything else is details.

Grades K-2: The Push and Pull of Winter

At this age, “force” is a magic word. They need to see that they are the source of the energy. We focus on the physical sensation of moving things across different surfaces—carpet vs. tile is the “winter ice” DIY activity they can actually do without a coat.

Grades 3-5: Engineering Through the Meltdown

This is the sweet spot for engineering. Students at this level understand that things should work, but they get frustrated when they don’t. According to Edutopia, “Learning engineering skills and concepts in elementary school can help build lifelong critical thinking and problem-solving skills.” 

We use the Engineering Design Process to explain why their “indoor sleds” stop moving or veer off course, turning a failed build into a data point.

“I teach grades kindergarten through fifth in our school’s STEM lab. It’s so hard to try to create a curriculum for that many grades and students (550+). Generation Genius makes it easy, fun, and an incredible learning experience. Plus, the DIY activities are made with inexpensive materials. All activities are grade-appropriate. We review the vocabulary and talk about the “before video” questions. Next, we watch the video, pause it at certain points to discuss, and do the Kahoot lesson at the end. The following week we performed the DIY activity.”

The “I Have 20 Minutes Before Indoor Recess” Version

No time to prep? Here’s exactly what to do:

Minutes 1-5: Ask: “If the floor was made of ice, would it be easier or harder to move your desk?” Let them talk it out. 

Minutes 6-15: Watch the Balanced & Unbalanced Forces video.

Minutes 16-20: Have them identify one “balanced” force in the room right now (like a book sitting on a desk) and one “unbalanced” force (the kid tapping their pencil).

That’s it. You taught a core standard while the rest of the hallway is probably watching a movie that has nothing to do with science.

Winter science activities is more than just making pretty crafts with cotton balls. It’s about understanding the physics of the world when it gets cold and slippery.

Don’t let the indoor-recess-insanity win. Use the videos and keep them learning.
