Water tricks

This term our Inquiry is centred around Water and we endeavour to finish the unit planning and designing a watering system for our school garden using recycled materials. 
To kick off the unit we enjoyed viewing some water tricks and finding science explanations behind them.

Today Thomas our science expert helped students make Obbleck and shared its explanation which answered the question of how does it be a liquid and become a solid?

Oobleck

Explanation

Cornflour is made up of lots of tiny starch particles that loves water and the water moves quickly around the  particles.

The water acts like oil and grease, so when you move it slowly the particles have time to move past each other and they can flow like a liquid.

So it is a solid when you move it around fast and the particles are jammed together  and the water  that was between them moves around the outside.

Now the particles are lumped together without the ‘grease’ and the mixture can no longer flow.

Garden Club

We learnt about compost, worms and nutrients that we can add to our garden to give it nourishments to grow. We got very dirty but it was a lot of fun!
