Kindergarten kids are naturally curious, which makes this the perfect age for introducing science. The Egg Experiment is a fun way for kids to explore density with a Sink or Float Experiment. This floating egg experiment is a simple science experiment for kids of all ages from toddler, preschool, pre-k, kindergarten, first grade, and 2nd grade students. ,Have a blast learning about density for kids with a why do eggs float in saltwater project perfect for spring and Easter Science when eggs are cheap!
Float Egg Experiment
Learn about density and salt water with an easy kindergarten science activity. This floating egg science experiment is a classic science experiment, and for good reason. This egg experiment is super EASY and teaches children about density. Discover why do eggs float in saltwater with preschoolers, toddlers, kindergartners, grade 1, and grade 2 students. Plus with this how to make an egg float all you need are a few simple materials you probably already have in your kitchen!
Kindergarten kids will be fascinated how salt makes an egg float. Use this opportunity to talk about density and why salt keeps things afloat! You’ll need a few things for this egg floating experiment:
- 2 eggs
- 2 jars
First, heat one jar of water so that it’s easier to mix the salt into it. This will save you time, but don’t let the kids touch the jar when it’s hot. If you live near the ocean, you can just use seawater as well for this experiment, but it will look dirty. Our salt jar has a pink tint to it because we used Himalayan salt, which is pink. If you use regular table salt, the saltwater will look whiter.
Ask the kids if they think the eggs will float in regular water. Ask if they think the eggs will float in salt water.
Why do eggs float in saltwater
In tihs experiment you will discover how much salt to make an egg float. Test an egg in each jar. The kids will likely be very surprised that the egg floats in one solution and not the other! Prepare to answer numerous questions about density and why this happens.
How to make an egg float
This Egg Sink or Float Experiment is all about density. Saltwater is denser than tap water, and denser than an egg. This means that in regular water, the egg will sink, because it is denser than the water. But in the saltwater, the egg is less dense, so it floats to the top. You can use this time to ask kids what other things might be less or more dense than salt water. Experiment with other items in your classroom or home for a full lesson on density.
