Let's find out about water with Kit and Pup! Kit and Pup are pirates on a sandy beach on the lookout for treasure. They search up and down the beach, but where will they find the buried treasure? Through their adventures Kit and Pup find out that sand is made of lots of tiny grains, can be poured and can be moulded into different shapes. In the live action investigation two little scientists use buckets and spades to compare the difference between wet and dry sand, and in the material world a little explorer waves from behind lots of tiny grains of sand.
