Moon Rocks and Earth Biscuits

This post is going to be filled with photos as there were just too many to choose from so I have decided to share them all! Our sensory play this week was related to our Space Topic. On Wednesday we combined baking soda with a small amount of water and black food colouring to make a crumbly powder (moon dust). We all enjoyed crumbling it through our fingers and squeezing it together (I actually didn't get many photos of this stage as I was too busy being involved!). We ended by adding just enough water to make our 'dust' into rocks and squeezed them together into the right shape. Then we put them on a tray and left them to dry overnight.

The next day we filled some squeezy bottles with vinegar, put one rock in each of our trays, and then squeezed a little bit of vinegar on to them. Guess what happened??? They fizzed and bubbled and erupted!




Some of us enjoyed the fizzing so much that we added more and more vinegar until the rocks had completely dissolved! Then it was time to get our hands into it and explore!






For some of us who weren't too keen to get messy, we poked around the trays with sticks and brushes. But some of us, like Lake, enjoyed the feeling so much that he was practically painting it up and down his arms!






Also this week our cooking session was topic related too.  We began by making some icing and colouring it green and blue. Then we very carefully spread blobs of it onto plain biscuits. When we gently jiggled the bicuits the icing blended together and made patterns that looked like the Earth!
