The+variables

There are variables in the washing of dishes

to make it a fair test** ||
 * ~ **The variable** ||~ **Explanation** ||~ **How we controlled the variable
 * ~ The temperature of the water || In initial experiments we found that temperatures are very big variable that controls the cleaning power of certain detergents. The hotter the water the faster it would clean. We had to find a way to keep the water exactly equal or as close as possible to make the test fair. || We controlled the variable by using boiling water at the beginning of the experiment, because would all be at the same temperature and cool down at similar rates. ||
 * ~ How thick the dirt was || Thick dirt takes more time to clean then thin dirt || We tried to make smears the same size ||
 * ~ The type of dirt || Some dirts are easer to clean then othes || Only one type of dirt was used in each test ||
 * ~ The type of surface the dirt was on || Some surfaces aer easier to clean then others || Only one tipe of surface in each test ||
 * ~ The amount of water || The ratio of water can vary the power of the detergent || We measured the water brfore it went into the testing beakers ||
 * ~ The amount of detergent || A larger amount of detergent will clean better then a smaller amount || We carefuly mesured our detergent before testing ||
 * ~ How long the washing went for || The time of washing afected the cleaning rate. || We used set times if none were clean we shoke them for a minute and waited again ||
 * ~ How much scrubbing there was || The amount of scrubing will remove stains Quicker  || We didn't scrub at all ||
 * ~ How things were drained or dried || Drying with a cloth will remove extra dirt || We drained them insted ||
