Recently, in Te Ngahere we have been doing science fair. We are testing, different types of washing powders to see which one is the best for removing stains.
I chose this topic because I want to help parents save their money on washing powder that doesn’t even take the stain out.
Our hypothesis is that we thought persil ultimate would wash the stain out the best because our research told us that persil ultimate contains ingredients to remove stains.
My hypothesis was correct because we researched what was in persil ultimate, persil ultimate contains enzymes like protease, amylase and lipase which breaks down protein.
I learnt that a controlled variable is the variable that you have to control through your experiment.
Something We would do differently next year is to do stains that kids actually spill on their clothes.
I am proud of finishing the board and being the first one finish.
