Place five or six articles in a beachbag, ask one child to come up close, close her eyes, reach into the bag, grab an item, and guess what it is. After child has guesses remove the item to confirm the child's guess. Put some of the items in the bag. Take out each item as the children name it. For any items the children can't recall, give them a clue and see if they can guess correctly.
Most children know that the sun makes things grow and that the sun is very hot.
Distribute a piece of construction paper to each child. Let each child chose five objects, and have him arrange them on the paper with the flat side down. Leave these in the direct sun for several hours, until the sun has bleached the exposed areas of the paper. Then let the children take their objects off the paper, noting the patterns produced by the sun. Here is summer's big warm sun.
