CSI - Mystery substances 2




ON THURSDAY WE WERE TESTING DIFFERENT LIQUIDS,TO SEE IF THEY WOULD REACT TO ANYTHING. TO KEEP OURSELVES SAFE WHILE WORKING WITH CHEMICALS, WE WATCHED A VIDEO ABOUT SAFETY. WE TRIED LOTS OF DIFFERENT THINGS TO SEE WHICH ONE WOULD REACT. THE HYDROGEN PEROXIDE REACTED TO THE YEAST IT BUBBLED UP. WE ALSO DID A PH TEST. IF YOU DON'T KNOW WHAT A PH TEST IS IT IS A TEST THAT INVOLVES LITTLE PIECES OF PAPER AND WHEN YOU PUT IT IN TO A LIQUID IT CHANGES COLOURS . TO SEE IF IT IS ACID, NEUTRAL OR BASE. IT WAS COOL BEING SCIENTISTS.
