The experience
Prepare a space for your scientist to work!

- Cut out the middle of the lemon and use a stick to pull it out, leaving a lemon bowl.
- Add food colouring in the middle of the lemon.

- You could even repeat this experiment using different colouring to make many different coloured explosions.
Good luck with your scientific volcanic eruption!
As you go through each step, ask your child – ‘what do you think might happen next?’ ‘What do you think is going to change when we add…?’ Talk about how in a science experiment, we make predictions and think about what could happen next and share these thoughts and ideas.
