Can you check this for grammar/mechanic errors? thank you!?

In order to conduct this experiment the materials needed are as follows: a 150 milliliter beaker, scissors, a centimeter ruler, ten grams of salt, ten grams of sugar, 310 milliliters of distilled water, a triple beam balance, a disposable diaper, tweezers, and a stapler. The amount of materials listed will be enough to complete one test for each solution. After collecting the materials, using the ruler and scissors, cut the diaper into three squares measuring five by five centimeters. The m of the original solution, diaper square size, time limit of absorption, and the water are all controls in this experiment and have to be equal for each test. Staple each side of each diaper square closed, in order to keep the Sodium Acrylate within the pad while the absorption is taking place. uming that the triple beamed balance is balanced, pour 110 milliliters of distilled water into the beaker and measure the m of the beaker in grams. Record the measurements in a chart similar to Data Table A on the following page. As progression increases, it is displayed in Data Table A that the original m measurement is equal during each test, this because it is one of the controls in this experiment.
