Activity 2 - Rain Drop Size, Science & Maths
Go over background knowledge; talk about different weather types; listen to sounds of rainfall. Then have a go at the investigations:
Measuring raindrop sizes
Predict how big raindrops are & if they are all the same size.
Hold paper in the rain for a few moments.
Bring it inside and draw round the splats, before they dry.
Measure & record the findings.
Use the investigation sheets as a guide, though you don't need to print it off.
With parental supervision, play with sponges in a bath, bowl, or paddling pool. Watch the sponge absorb the water and, when heavy with water, hold it up to let the water drip out, to make a rain shower. Gently squeeze it to make more come out. You could explore using different sponges, bags with tiny holes, or a colander. What do you see? What happens?
Use simple weather and Mathematical vocabulary to explain your play for example droplets, rain, clouds, shower, storm, fine, heavy, tiny, narrow/narrower/narrowest, wide/wider/widest, large/larger/largest, small/smaller/ smallest.
