Below are some chemistry experiments that children can do at home


There are many ways of making this. We have shown only one here. You can add things like colour; for example, add yellow dye and mix in miniature bees (erasers) to make it look like honey, or red dye with little black beads to make it look like watermelon slime.

You will need:

  • Mentos (this has the best results though you can use other makes)
  • A big bottle of fizzy pop 
  • Make a  long dropper for the Mentos using the cardboard (put a pen across the bottom of the cardboard to stop the Mentos dropping through until you are ready)


  1. Fill the tube with Mentos
  2. Place the tube INTO the mouth of the bottle of pop 
  3. Pull the pen out so the Mentos drop into the bottle-THEN MOVE BACK QUICKLY
  4. Watch the pop explode as the Mentos mixes with the carbon dioxide in the bottle.


Invisible Ink

This invisible ink is non-toxic and the kids will love this as they can amaze their friends with it.

You will need:

  • Water
  • Baking Soda
  • Paper
  • Measuring cup
  • Paintbrush 
  • Purple grape juice 


  1. Mix baking soda and water in equal amounts. 
  2. Use the brush and write a message on the paper with the solution
  3. Then paint over the message with the juice and the message will appear as if by magic!

Here is an activity for secondary school students to attempt. This will help them to familiarise themselves with The Periodic Table.
