Egg Science Water Experiment Sink and Float

Easter egg science for preschool play and learning! Do these plastic eggs float or sink? What will sink the egg? These are all great questions for preschool science to encourage problem solving, spark curiosity, and develop all sorts of great language skills! We love using these plastic eggs for all types of play including math games, slime science, color matching, fizzy science, races, and sensory play!

Easy Easter Egg Science Water Experiment

Experiment sink or float concepts with plastic eggs.

The idea of this egg science experiment was to see what would sink the egg! I chose three fillers: mini bells, pompoms and marbles. I also chose 5 eggs for each filler. I labeled all purple 1, all yellow 3, all pink 5, all orange 7 and all green 9. We filled each egg with the right number of bells, pompoms and marbles so that we could compare what happened as we put them into the water. We talked about what we thought might happen before we dropped the eggs into the bin.

All the purple eggs floated with one of each item in each of the purple eggs. (Note, tape over holes in plastic eggs! (My husband made a simple observation before we started. Glad he was with us!)

Hard to get great photos, but it was fun to see how when we added more to each set of eggs, the quicker they sank. Perfect way to show sink and float with this simple egg science idea!

I love how our science experiments, like this egg science play, open up great communication between us. They have really gotten him to look more closely at what is going on around him!

We filled one additional egg with 12 marbles just to see what would happen since the egg with 9 marbles sank almost all the way. The blue egg completely sank! Now thats experimenting with egg science!

How many marbles, bells and pompoms will make the egg sink.

Lots of fun testing and lots of counting in this egg science learning activity.

Afterwards, this egg science activity makes for some hands on water sensory play too!

There are so many wonderful and easy way to play with plastic eggs! I bet you have plenty around to try these fun ideas with right now! Gather simple supplies and try some egg science experimenting today!
