0.5*(Curriculum) + the Chemical Cupboard / ((HOW2 + (Internet - Fear)^2) = Science with Mr Dave
I've always wanted my own chemical store to play with. Now, it's part of my job! The kids are learning, but I don't think they realise a lot of my "let's see what happens now!" banter isn't actually put on for their benefit... ho hum. Today we made some sulpher dioxide, did a sacrificial electrolysis of copper in a copper sulphate solution and demonstrated the greater reactivity of aluminium by dissolving some foil in more copper sulphate. My attempt to make slime with PVA glue and Borax sadly didn't work. Tomorrow, sodium and water...
