Materials and Water

Goal: Name what things are made of, and test which ones float, sink, soak up water or keep us dry.

For parents: A good scientist guesses first, then tests. Always ask 'What do you think will happen?' before you try.

Do together

  1. Sink or float

    You need: A shallow bowl, a little water, a large metal spoon and an unbreakable cup

    Stay within reach throughout. Guess what will happen, then lower each item into the water and observe. Try the cup upright and on its side; whether water enters can change the result. Keep items out of mouths, wipe spills and empty the bowl afterwards.

  2. Umbrella test

    You need: Squares of paper, cloth, plastic, foil; a cup; water

    Cover a cup with each material and pour a spoon of water on top. Which keeps the inside dry? Which would make a good umbrella?

  3. What is it made of?

    You need: An adult-selected wooden spoon, metal spoon, unbreakable cup and cloth

    Name the materials together: wood, metal, plastic and cloth. Let your child describe how the safe objects feel. Look at glass only where an adult has placed it securely; do not handle or tap it.

Talk about it

  • What happened to the spoon when we lowered it into the water?
  • What is your chair made of?
  • Which material would you use for a raincoat? Why?
