Easter is a great time to try some fun, eggy experiments. We’ve put together a list of our favourites for you to try.

First up is removing the shell from a raw egg! All you need to do is place a normal egg in vinegar for a few days and then the shell simply rubs off, leaving behind the squishy membrane.

How to bounce an egg

You will need

Eggs

Jars/containers

Vinegar

Instructions

Place an egg into a container of vinegar, making sure it’s completely covered.

Leave for 24 hours, then carefully rinse the egg. You should be able to gently rub away the shell, leaving behind the membrane. If you can’t rub away all the shell, place the egg in fresh vinegar for another few hours and then rinse again. 

Once the shell is completely removed, gently squeeze your egg.

Next try dropping the egg into a container (incase it breaks) the egg should bounce. Experiment by dropping it from different heights.

Extension ideas

Place an egg with no shell into water coloured with food colouring. Over a period of a few hours the coloured water will pass through the membrane into the egg making the inside the same colour as the water.

The egg will also increase in size as it has extra water inside. If you prick the egg with a small needle a jet of water should shoot out because of the increased pressure inside the egg.

Why does this happen?

Vinegar (which is acidic)  dissolves the calcium carbonate in the egg shell, leaving just the membrane intact.

Egg drop experiment

There are lots of variations of this investigation you can try. Our favourite is putting boiled eggs into sandwich bags filled with different items to cushion the fall to find out which protects the egg the best. Another variation is to build a landing pad from junk modeling materials to drop the eggs onto.

Materials

Boiled eggs

Sandwich bags

Materials to test – cotton wool, couscous, rice, bubble wrap.

Instructions

Add the same amount of test materials to different bags.

Place a boiled egg in each bag and drop from the same height.

Examine the eggs to see which are most damaged.

Extension ideas

Try dropping the eggs onto different surfaces. Does it make a difference?

More Easter science ideas

Rolling eggs

Wrap real or chocolate eggs in different materials, such as bubble wrap and kitchen roll and time how long each take to roll down a slide or ramp. You should find the materials with a rougher surface roll more slowly than those with a smooth surface. This is because there is more friction between the wrapped egg and the ramp surface, which slows the egg down.

Or how about these...

Make your own Easter eggs 

If you have an Easter egg shaped mould, making your own Easter eggs is a great way to learn about changes of state. What treats would you hide inside? Do you think some would be noisier than others when you shake the egg?

Create an extra special egg hunt

Make a treasure map, thinking about directions or create codes that have to be broken to find Easter treats. For older children you could make a code breaker for them, or ask them to design their own.
