What happens to water when it’s freezing cold?
Freezing happens when molecules of liquid get so cold that they slow down enough to hook onto each other to form a solid crystal. We watched this happen in slow motion on our iPads.  It thought it looked like crocodiles, birds or leaves. We then made our own ice cubes, we poured the water into the trays and placed it in the freezer.

The ice cubes are sticky and cold. I see patterns inside them . They melt in my hand but they are still cold ..

That was something cold but what about hot things? What happens when you add heat to popcorn?

Popcorn pops because each kernel has a tiny bit of water inside it. When the kernels are heated up to the point where it exerts enough pressure, the kernel bursts open. The soft material inside puffs up as it explodes. This then cools and forms the odd shapes we know and love to eat.

The shapes got the children discussing some safety rules; “it is very hot”, “we wouldn’t touch it”. Then they started to chat about what shapes and textures had been produced. “Mine looks like a horse.”  “I found the seed, it is hard.” “My popcorn is crispy.”

As the popcorn comes from seeds we have decided to plant them and grow our own popcorn plant! We have put the seeds in the green house. Let’s see what happens next!

We have had a lot of fun today trying out our experiments for science week and learnt lots of new information. We have lots of different experiments to try out throughout the week and we cannot wait!
