Try these cool experiments, we have and they all work!

Bouncing raisins

Number of Players:

1+

What You Need:

Vinegar, baking soda, one tall clear glass or jar, water, and eight or more raisins.

Activity:

Begin by half filling your glass or jar with water. Then add the vinegar and baking soda to the water. The mixture in the glass will begin to fizz. Drop the raisins one at a time into the glass. The raisins may initially sink the bottom but eventually they will rise up and then sink, then rise again. Children should be able to watch the raisins bounce for up to an hour.

Floating Egg

Number of Players:

1+

What You Need:

Egg in its shell (it can be boiled or raw), an almost full glass of water, and a teaspoon of salt

Activity:

Carefully place the egg into the glass of water. Initially the egg will sink to the bottom. Pour in two teaspoons of salt and stir carefully around the egg. Continue to add the salt and stir until the egg rises. Eventually the egg will float as salt water is denser than fresh water and the egg will weigh less than the water.

Making Butter

Number of Players:

1+

What You Need:

·                                 Clean Jar

·                                 Double Cream

·                                 Salt

Activity:

Put in double cream into a clean jar until it is about half full. Add a pinch of salt.

Shake the jar for 10-15 minutes - you may need the help of a friend as it gets very tiring! You should notice that the double cream and salt is separating into a lump of fat and a milky liquid.

Take the lump out of the jar and put it on a paper towel so that you can wrap the towel around the lump and remove any excess liquid. Taste the lump - it is butter!

Make rain

Number of Players:

1+

What You Need:

·                                 Saucepan

·                                 Water

·                                 Ice-cubes

·                                 Oven mitt

Activity:

Ask an adult to boil some water in a saucepan.
tray cool the steam from the boiling water, changing it back into water in the form of rain drops.
Using oven mitts to protect your hands, hold a tray of ice above the steam.

Drops will begin to fall like rain from the tray! Why?

We have had lots of learning and it was fun.
