EGG DETECTIVE
In this experiment, your children will be trying
to discover which of two eggs are raw and which is hard
boiled.
|
Set out two eggs. One raw and one hard boiled. |
| |
Ask your child if she can tell which egg is hard
boiled (without cracking the egg). |
| |
Have your child try, smelling it, lifting it,
shaking it, rolling it, laying it on it’s side and
spinning it. |
|
Finally, have her hold the eggs up and spin them
like tops. |
|
Have her notice that one egg spins nicely and
one flops over. |
| |
Explain that hard boiled eggs can spin easily
because they are solid inside, while raw eggs wobble
because they are liquid inside. |
TURNING EGGS
INTO RUBBER
For this activity, you will need a raw egg, vinegar
and a small plastic glass. |
|
Have your child place the egg in the glass. |
| |
The, have him pour vinegar over the egg until
it is covered. |
| |
Set the glass aside for two days. |
|
Pour off the vinegar and dry off the egg with
a paper towel. |
|
Have your child squeeze the egg. |
| |
Have him notice that the egg now feels and acts
like rubber. |
