Week+1

Week 1:


 * Warm up activity:** Draw a scientist- discuss


 * Do experiment**- Dancing saltanas

Mix bicarb, raisins and vingar.

__Explanation__: Bi-carb soda causes a chemical reaction with vinegar producing a gas called carbon-dioxide. The bubbles stick to the currants, floating them to the top. When the currant hits the surface, the bubbles on the top pop so they sinks again. The reason why the currants floats to the top is because the bubbles stick to the sides of the currants and make the currant more buoyant. Buoyant means that something floats more easily. The bubbles make the currant float the way a life jacket makes a person float.


 * Talk/ discuss what we saw, learnt, surprised, interesting...**


 * KWL.**
