- Chameleons ( Girgits ) change colour to blend in with their surroundings — and also when they are angry or sense danger.

- Hint — Chameleons have special cells with tiny crystals; the cells expand or contract to reflect different colours of light. Yes, it's reversible — the chameleon can change back!
Every kitchen, garden, beach, and mountainside is a laboratory full of physical and chemical changes. Once you can spot which is which — and which can be reversed — you start seeing the chemistry of everyday life everywhere you look.
