    My science inquiry! My science inquiry! Presentation Transcript

    • AIM My aim is to find out what is the most effective washing powderout o f spree supreme and fab.
    • Equipment and method
    • EQUIPMENT AND METHOD STEP ONE: make sure you have all the equipment below. STEP TWO: get one cup, coffee and boiling water then put one tea spoon of coffee in the cup and pour 170ml of boiling water in to the cup with the coffee by messaging jug. STEP THREE: please the 10x10 white material next 2 the cup on the bench then put 2 teaspoons of coffee on the material and leave them on the table to dry over night. STEP FOUR: grab the now stand material of the bench and get three bowls and put the three different washing powders in one bowl each with 100ml of hot boiling water in each bowl STEP FIVE: place the stand material in one bowl each then steer them for 2 minuets each and sock them for 3 minuets each and get them out and let them dry over night then test what one is the cleanest out of the spree, fab, and supreme.
    • Variables and fair tests The variable in this experiment was the washing powders I changed them three times. The fair tests is that I got the exact measurement. My experiment was done twice to do it again how I will do this different next time was it turned out better the second time
    • Disconclutions and conclusionsO The thing that went wrong the most was that I used 10 by 10 coffee coloured material instead of white calico material. I can improve this experiment next time by stirring the powder together with a bit more of hot water and sock it for a few more minuets. The safety of it is high because of the hot water, you should get a adult to pore the hot water. The time of this procedure is 1 hour not counting the time for the coffee stains drying over night and finely the cost was that my experiment was limit to 3 washing powders because of the cost.
