Fun with Science Resources

Here are some fun Science activities that you can do at home.

Rainbow in a Jar

This is one of my favourite Science activities. Enjoy exploring density in this fun and practical way.


Making a homemade sundial is one of the lowest-prep science experiments you can do: You just need a dowel or a good stick, a paper plate, and a marker. Mark the position of the dowel's shadow every hour, and you've got an easy opening into talking about the Earth's rotation. The next day, see if your sundial tells accurate time while playing outside.

Orange Fizz


  • An Orange or Clementine
  • 1/2 Teaspoon Baking Soda


  1. Cut the orange into slices or peel separate into sections
  2. Dip a slice or section into the baking soda
  3. Take a bite! As you chew, it should start to bubble in your mouth

How does it work?

When acids and bases mix, you get some exciting chemistry! Oranges and other citrus fruits are filled with citric acid. It is a safe acid, and it’s what gives oranges, lemons, and limes their sourness. Baking soda is a base, the opposite of an acid. It’s also safe, but doesn’t taste very good on it’s own, and will give you a tummy ache if you eat a lot of it. As the citric acid and baking soda mix, it makes millions of carbon dioxide bubbles, the same gas you breathe out, and the same one that makes soda so fizzy.

Lava Lamps

A science club favourite of mine, have a go at making a lava lamp at home. Can anyone successfully mix two colours together?

Fireworks in a Glass.

This is a very cool, simple and fun experiment, and also completely safe, just
don’t drink the water!


Which solids dissolve in water?

Cornflour Slime

Have fun exploring what happens to this liquid when you push and press it. Discover why it is 'different' to other liquids.

Rainbow Colour Mixing

Discover what happens when you add food colouring, milk and a dash of washing up liquid together.
