Science is not always something you need to learn in school and science experiments don’t always have to be done in a lab. With these simple science experiments you can do at home, you can impress your friends, parents, and learn something new, too.
The Rock Candy
You need a long piece of string, pencil, paper clip, 1 cup of water, 2 cups of sugar, and a glass jar.
Start by tying the string around the middle of the pencil and tie the paper clip at the other end of the string. Position the pencil over the opening of the jar so that the string hangs down in the jar, making sure it doesn't touch the bottom. Put aside.
In a pan boil the water and pour 1/4 of the sugar into the water until it dissolves. Keep adding all the sugar making sure every bit dissolves. Pour the hot sugar solution in the jar and submerge the paper clip and string in it. Allow it to cool, and in about a week you'll have rock candy to eat.
Soda and Mentos Geyser
Kids will definitely love this one and it's so easy to do. All you need is big space where you can make a mess, a 2-litre bottle of soda, and a packet of Mentos.
First thing you need to do is open the soda carefully and then unroll the Mentos candy. Drop all the candy in the soda bottle and step back a few paces - quickly. Watch the geyser blow up and measure the height. The current record is 21 feet.
Of course, there are all the simple things you can do like sprouting carrot tops or putting white daisies into coloured water and watching the petals change colour. Remember, just because you’ve done them before doesn’t make them any less exciting to your children.
Make science fun and play with it at home.
