WHY POPCORN POPS

This term we have been learning about where our food comes from. We investigated why popcorn pops. First we looked at a corn kernel. It was solid, hard, smooth, pointy, light, teardrop shape, yellow, hard outer shell and transparent. Here's a Bubbl.us I made about it.

After popcorn is popped it's fragile, puffed, very light, has holes in it, larger, cloud shape, white, brown inside and edible. Here's another bubbl.us about popping corn.

After we looked at the corn kernel and the popping corn we were wondering what was causing it to explode.We found out that the moisture in the kernel was making the moisture evaporate then there was no more room for any more steam and that made the corn kernels explode.

TOOTH FAIRY DESCRIPTION

We are taking part in the Tooth Tally Project.

One of our first tasks is to draw a picture of the Tooth Fairy.
We can't draw whatever we imagine the Tooth Fairy to look like.
We are basing our drawing on a description that we have been given. All the children in the 250 classes taking part in the project have been given the same description.

We used Bubbl.us, a mindmapping tool, to help organise the information we have about the Tooth Fairy.
Click and drag the Bubbl.us around to see all of the mindmap.

This is what each of us will have in common with our drawings but will each drawing look the same?

What do you picture the Tooth Fairy looking like?
