Why not investigate floating and sinking.
You could do this with a bowl of water, in the sink, or even in the bath tonight!
Collect bits and bobs from around the house and remember to predict what you think will happen before you investigate.
Use water to write a message
If you have a paintbrush great, or you could just use your finger.
If it’s a nice day use water and a paintbrush to paint your
fence, wall or path and watch it dry
You could practise writing your name, letters, numbers
or writing secret messages.
