Constants (at least 3) Norm wanted to know if adding peat moss to sand would affect its ability to hold water. He put 200mL of pure sand into container A. He put a mixture of 80% sand and 20% peat moss into container B. He put a mixture of 60% sand and 40% peat moss into container C. He put a mixture or 40% sand and 60% peat moss into container D. He added water to each container and measured the amount of water the contents would absorb. He dried the sand and peat moss and repeated the experiment 5 times.
1.What is the ratio of sand to peat moss (IV) 2.What is the amount of water the contents would absorb (DV) 3.What the sample with pure sand (control) 4.5 repetitions 5.Containers, Amount of Dirt, Water (and many more)
