My top three Easter experiments

It’s almost the school holidays, so I am going to share my top 3 Easter experiments with you. I know the children only just went back to school but I’m looking forward to the changing of the rules on 29th March which means we can actually leave the house! Yipeee! We’ll be heading to the beach and one of our favourite country parks which are close but not quite close enough to count as “your town or village”. What will you be doing?

If the weather fails us, which is distinctly possible with those pesky April showers then you need to have some indoor activities to fall back on, and my top 3 Easter experiments are super simple so they’re a great place to start.

Easter Experiment # 1- Floating Eggs

Easter Experiment floating eggs

This is a fab activity to explore density and dissolving with your Explorer, can you get the egg to float on the top and to sit in the middle of a glass of water?

You will need

  • eggs
  • salt
  • Water
  • spoon
  • beakers


  1. Fill a beaker half full with water- pop in your egg, does it sink or float?
  2. In another beaker add some more water and stir in some table salt, one spoonful at a time until you can no longer dissolve any more.
  3. Pop in your egg- what happens?
  4. Now pour the fresh water into the salty water, where does the egg end up?

What’s the science?

When we pop an egg into tap water it sinks to the bottom because the egg is more dense than the water (f your egg is floating in tap water it means it’s gone off!). When we dissolve salt into the water we increase the density of the water, and comparatively the egg is less dense, so it floats!

Density is all about how closely packed together the molecules are in a particular material, the more molceules there are in a given volume the greater the density.

Easter Experiment # 2 Bouncing Eggs

How would you take the shell of an uncooked egg? Could you do it without it breaking?

In this activity I’ll show you how, just be careful with the bouncy egg as it’s very fragile, with the contents protected only by the delicate membrane. This is one of those activities that really makes children (and adults) exclaim “wow!”

You will need

  • Egg
  • Vinegar


  1. Pop your egg into a beaker
  2. Cover it with vinegar and leave for 24 hours
  3. What happened to the shell?
  4. Very carefully (from close to the surface), drop your egg- it should gently bounce! It’s very fragile though so do be careful!

What’s the science?

The shell of an egg is made of calcium carbonate. When you leave the egg into the vinegar the calcium carbonate and the acid in vinegar begin to react. You’ll see little bubbles forming on the egg, this is carbon dioxide and is produced as a result of the reaction. You may also notice that the egg gets larger because some of the vinegar is absorbed into the egg through the membrane.

Easter Experiment # 3 Protect the Egg

What if Humpty Dumpty had better protection than a shell when he fell off the wall? Let’s investigate some materials which could’ve saved all the King’s horses and all the King’s men a whole lot of trouble!

You will need

  • Eggs
  • sandwich bags
  • different materials (bubble wrap, foil, paper, packing beads etc)


  1. Choose your protective materials, predict which will be the best at protecting your egg from breaking when dropped from a height
  2. Wrap your egg carefully in your chosen materials and pop it into a sandwich bag (just in case it breaks)
  3. Drop your egg from 1m (you can always go higher if you want!) and test each material. Which protected the egg the best?

What’s the science?

You need to create something that can absorb the energy the egg gathers as it accelerates towards the ground. A hard surface will crack the egg so you have to think carefully about how you can protect it. Decide which materials would be best at protecting the egg and maybe think about devising a way to slow the egg’s descent.

So there you have it, my Top Three Easter Experiments, happy exploring and happy Easter!
