Testing for starch -3rd Class

-
Third Class completed an experiment testing a variety of materials for Starch. Firstly we found out what Starch is. We then placed a variety of items onto Paper Plates. We mixed some iodine solution with water. We recorded our predictions before carrying out the test. We tested for Starch in groups. Third class enjoyed testing for starch in materials by dropping some iodine solution on to them. We were amazed to see the  the item turning a blue/black colour if starch was present. If starch wasn't present it remained the orange/brown colour. If we were to carry out this experiment again we would test even more items for Starch.

Testing for acids and bases - 4th class

-
4th class investigated acids and bases. First we examined the pH scale, and saw where common household items appeared on it. We made indicator by steeping red cabbage in hot water for an hour. We ensured fair testing by using exactly 5ml of indicator and 5ml of substance under test in each case. We found that lemon juice was the most acidic item we tested, with bicarbonate of soda being the most alkaline. We found that tea and coffee are both acidic, but that reading the indicator colour level was hard because both tea and coffee are brown.
