Kids will have fun making their own garden fairies, especially over summer when plants are in full bloom. Teach them the names of the flowers that you use, discuss the different shades of colour and how plants grow.
Have a go at creating your own mini aquarium in an old jam jar. Its easy to do and the kids will love how the glitter and sea creatures swirl around inside the jar. The aquariums also make great party decorations and party favours for kids to take home instead of a party bag.
Have a go at making your own rainbow salt tray. Toddlers and preschoolers will have lots of fun watching the colours come through when they draw pictures, create patterns and write their name in the salt. It is cheap to set up and you will already have the items at home.
