Mixing things up!

Our topic this term  is 'How the world works in the kitchen'.  We discussed what it means to mix something.  We wondered what would happen if we mixed water, flour and salt.  

Some clever children thought we would make a dough!  

We started adding the ingredients, the mixture became very sticky and sloppy.  

We brainstormed how to change it to make a dough we could shape.  

"We could add more...water", some children replied.  

Good scientists make predictions and then do an experiment to see if their guesses were right.  

We added more water and... it got runnier!  "More flour!" we decided.  

Finally the mixture made a dough.  

We each got some to shape. The next day once the dough had harden we painted our creations.

The ingredients are mixed together

It's looking a bit runny!

We tried adding more water

The finished creations!

Next we wondered what would happen if we changed some of the ingredients.  Would the dough be the same if we used water and cornflour?  We first noticed a difference in how the cornflour felt.  "Its very silky" said Liam.  This time we added the water slowly and watched how the mixture changed.

The mixture was hard but runny at the same time!

The mixture was very thick and hard to mix

The mixture looked like runny liquid but it moved very slowly when we tried to pour it.

Lots of messy fun!

We decided this mixture was no good for shaping like a dough.  We had to take our table outside it was so messy!

As the mixture dried it turned into a chalk-like texture.  Lucky Jake had his digger to help scrap the table clean!

By the end of lunchtime the table was clean again.  Good job guys!
