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.
