Something short and sweet.
I have mentioned before that I home educate my two little ones and I’m going to start sharing some of our activities. There is nothing special about these, anyone and everyone can do them.
This experiment has been taken from The Everything Kids Magical Science Experiments Book by Tom Robinson. It has all the information you need, ways to expand a task, real world examples, fun little games and tip bits to enjoy. There are American terms, but nothing that takes away from the fun!
WHAT WE USED
A clear drinking glass
Fizzy (carbonated) drink (we used lemonade)
Raisins
WHAT WE DID
1) To start, make sure the glass is cleaned and dried thoroughly.
2) Fill the glass with the fizzy drink
3) Now drop in a raisin or two and see what happens.
This experiment shows buoyancy (determines whether something floats or sinks). The raisins (should) initially sink to the bottom of the glass, as they are heavier than the liquid. Then you will see the bubbles of carbon dioxide (the gas which makes the drink fizzy) gather in the skin creases, eventually lifting the raisin back to the top. At the surface the bubbles burst as the gas is released and the raisin will drop back down. This repeats until there is no more carbon dioxide (the fizzy drink goes ‘flat’).
This helped to keep the Little Ones occupied on a rainy day.
Enjoy!
