Use things from around the home to construct a volcano and make it erupt using a chemical reaction.
Suitable for kids aged 5+, with adult supervision
You Need (for structure):
What you need for this project will depend on how you choose to make the volcano structure. If you are in a hurry you can use moist soil or sand outside, or you can spend longer making a paper mache or foil structure. Each of these methods are descibed below.
You Need (for eruption):
Plastic cup, container or bottle
Baking Soda
Vinegar
Detergent
Red dye

Moist sand or dirt volcano This is the quickest way to make your volcano. Just mound moist

Suitable for kids aged 8+ with parental supervision
You Need:
Garbage Bag
Duct Tape (or a plastic packing strip)

Small plastic lid (or saucer) to sit the sugar cube on
What to do:
Practice using the eyedropper by sucking-up some cold tap water from a glass (or other container), then gently squeezing the water back into the glass one drop at a time. Dont squeeze too hard or the water will come squirting out as one stream. You need to be able to master raining one drop at a time to continue with the rest of the experiment.

Plasticine

Can you keep your ocean-marble on the spinning cardboard-earth for three whole rotations!? A fun way to model the spinning earth and learn about how spin effects weather.
