Ready to race? Let’s dive into an exciting Easter science and physics experiment using plastic Easter eggs! Turn those colorful plastic eggs into racecars and set up an egg race experiment that’s simple, fun, and packed with learning. Easter STEM activities like this are perfect for young scientists eager to explore motion, speed, and forces!
RACING RAMPS
What makes things move? How do objects speed up, slow down, or stop? This Easter egg race introduces kids to some key physics concepts through playful learning. In this experiment, we’ll explore Newton’s Laws of Motion, gravity, and the role of friction—all while racing plastic eggs down homemade ramps. Perfect for budding scientists, this experiment can be adapted for all ages!

Supplies:
- Plastic Easter eggs (variety of sizes)
- Plastic rain gutters (or cardboard ramps with bent sides)
- Stopwatch (optional but adds a fun element for older kids)
- Towels or fabric for friction experiments (optional)
- Marbles (optional, for adding weight)
How to Set Up the Egg Races:
Build the Ramps: If you don’t have rain gutters, create ramps using cardboard. Bend the sides slightly to keep the eggs on track. You can experiment with different angles for your ramps.
Choose Your Racers: Use different-sized plastic Easter eggs. Add marbles to the eggs to change their weight for more variety.
Make Predictions: Ask your young scientists what they think will happen when the eggs race down the ramps. Will the bigger egg be faster? What happens if we change the ramp’s angle? Get them thinking like engineers by asking, “What do you think will happen if we make the ramp steeper?”
💡It’s never too early to discuss the scientific method and variables.
Start the Race!: Place the eggs at the top of the ramp and let go. Use a stopwatch to time how long each egg takes to reach the bottom. Compare the results for different-sized eggs and different ramp angles.
Science Information: Ramps and Physics
This simple race introduces Newton’s First Law of Motion: An object at rest will stay at rest unless acted upon by a force. In this case, the eggs won’t move until you push them or tilt the ramp. Once the eggs are in motion, they will continue moving until another force, such as friction or the floor, stops them.
As the eggs race down the ramp, gravity pulls them toward the ground. The angle of the ramp influences how quickly the eggs move—steeper ramps mean faster races because gravity has a greater pull.
You can also introduce Newton’s Third Law of Motion: For every action, there is an equal and opposite reaction. As the egg rolls down the ramp, the force of the egg against the ramp is balanced by the force of the ramp pushing back.
More Science: Potential and Kinetic Energy At the top of the ramp, the eggs have potential energy—stored energy that has the potential to do work. Once they start rolling, that potential energy is converted to kinetic energy—the energy of motion. The steeper the ramp, the more potential energy is transformed into kinetic energy, leading to faster egg races!
Extension Activities for Older Kids:
- Friction Experiment: To explore how friction affects the race, place a towel over one of the ramps and compare how fast the eggs roll on the towel versus a smooth surface. Friction is the force that resists motion between two surfaces, and it will slow down the eggs.
- Exploring Mass and Speed: Add marbles or small objects inside the eggs to change their weight. Test how the added mass impacts the eggs’ speed. Heavier eggs may roll faster on a steep ramp, but the added mass can also increase friction, which slows them down.
- Ramp Angle Challenge: Let older kids experiment with different ramp angles. Use a protractor to measure the angles and record which angle results in the fastest or slowest egg races.

Gravity Experiments: Explore how gravity pulls objects down by experimenting with different objects and surfaces. Which ones fall faster? What slows objects down?
Car Races: After racing eggs, try using toy cars or balls. See if the same principles apply!
Egg Drop Experiment: Test the durability of your plastic eggs by creating protective structures to keep them from cracking when dropped from a height. This activity connects engineering to physics!
How fun! Another idea would be to test how weight affects the race.
You can also test the effect of mass by adding items inside the eggs to make them heavier! 🙂
That looks like fun! I love that you could use the ramps with other items too. I’m storing up ideas for summer’s rainy days.
What a fun way to play with physics! I bet it was fun to watch the eggs wobble their way down the ramp too!
Thanks! We enjoy trying out all sorts of things in an easy to manage way for my little guy!
Yes you could! Could even bring them outside too! I bet we will get our $5 worth!
What a great exploration!! Thank you for sharing at Sharing Saturday!!
Thanks Carrie! We like simple fun!
