Fair testing in CH

​Team CH were asked the question “Will a bean plant grow better in the dark or in the sunlight?” We decided that we would plant some bean seeds and place some in the dark and some in the light. But, before we could plant anything we needed to ensure our test would be fair. In order to make the test fair, we measured out 40 cubes of soil using the balance scale and poured the soil into a bag. Next we each pushed one seed into the soil and pour ten ml of water into our bags. Finally we made our predications and the adults put our bags in the sunlight or in the dark.
