Eggs with no shells have to be one of the things my children find most intriguing. We made one for my 4 year old to show her nursery class last week.
What happens to an egg when you drop it? It smashes.
So how can we make an egg bounce?
First place it in some vinegar for a couple of days to remove the shell. You should be left with this.
Be very careful when you wash the egg, as one of mine did break.
To bounce it, drop carefully from quite a low height, the egg should bounce up from the surface. Can you measure at what height it breaks? Or try bouncing on different surfaces?
How about drawing a table to demonstrate your results?
If you don’t want to break the eggs, how about shrinking them?
We also have more eggy experiments here.
Key stage 1
Ask the child to predict if an egg can bounce using past experience of the properties of the shell.
Obtain and present evidence
Did you draw a table to demonstrate how high the egg bounced?
Consider and evaluate evidence evidence
Were the results as expected?
