CHEM LAB! WOW! Physical reactions are so…yesterday! Let's mix it up and see what happens! Lots of safe chemistry experiments to boggle your mind! Watch physical and chemical reactions and what makes them work. Observe liquid Nitrogen, make your own desiccator, grow alum and copper sulphate crystals, get ready for an instant snowstorm, and some Green Power science! All reactions are done outdoors and students wear protective goggles.
