An activity where children can see coloured water stain flower petals.

In this issue we investigate how water gets from the soil to the top of a plant, solar kits for learning about electricity and renewable energy, and launch the 'Falling seeds and biscuits' Primary Competition. There's also an important safety alert about using high powered batteries in circuit work and advice on chemical storage.

A guide to all our dissection resources.
