We decided to experiment which materials would be the most practical in making an effective umbrella. The children made their very own umbrellas out of a variety of materials, then they dropped water onto these. We all watched carefully to see which umbrellas would absorb or repel the water. This was measured by observing the number of drops and the length of time that they stayed on the umbrella.
Children made umbrellas from newspaper, plastic, tissue paper, card board, and crepe paper. Can you guess which were the most waterproof? That's right, it was the PLASTIC umbrellas that repelled the water droplets.
Finally, we decided to work together to make one big umbrella made out of lots of different materials!
