Keith's Reflection on week 5

What we we done so far?- Creating a condenser using a plastic container and black papeer which can condense water from unpurified dirty water into clean water.We have also managed to condense some of the dirty water into clean water but the condensed water was only half the container of dirty water we originally had.

What do we want to do next?-Replace the container with a bowl made of metal and are not going to use the black paper.

What have we learnt?-Although black is a good absorber of heat,metal is a better absorber of heat and we need metal to increase the rate of evaporation and condensation in our experiment.
