Experiment time!!!
Materials
200g of cooking chocolate
A stove/microwave
A wooden spoon
A heat proof bowlSlide7
EXPERIMENT TIME!!
Method
Gather materials
Put the cooking chocolate into the heat proof bowl
If you are doing this on the stove put it on the stove and continue mixing until melted
If you are doing in the microwave put it in the microwave in 30 second intervals until meltedSlide8
Experiment time!!
Extension
If you are curious to see how a liquid turns into a solid, place the chocolate onto some baking paper on a pan and place in freezer for 10 minutes.Slide9
Outcome
What should of happened by the end of this experiment is that the chocolate should of melted into a liquefied form.
If you did the extension part of the experiment you would of seen how the chocolate turned back into a liquid.
