Floating and Sinking

Floating and sinking 

This week we read about the Gingerbread Man. When the Gingerbread man got to the river where the Fox was waiting, I had the children think about what they might be thinking using the picture below as a prompt. 
We all agreed that the Fox was thinking of a cunning plan to eat the gingerbread man and the gingerbread man simply thought the Fox was being a friend by helping him across the water.

We then discussed what would happen if the gingerbread man had to cross the river on his own... what would happen to him? We then came up with an experiment to test out our ideas using a ginger nut, a cup of water and some M&M's (these were our gingerbread mans buttons).

We learnt how to 'predict'. A lot of us predicted that the ginger nut would sink in the cup of water... but in fact it floated! It was only until we moved the cup that the ginger nut sank.

It was also very interesting to see how the colour on the M&M's came away and changed the colour of the water... We were all super shocked to see how much food colouring goes into each M&M. Not so good for our tummies!

Here is Hannah's prediction she wrote up herself!

The ginger nut experiment

My prediction was right. I was super shocked that the ginger nut floated on the water because I thought the water was going to suck up the ginger nut biscuit and make it smaller. I thought it would disintegrate.
