Does Organic Material Affect Water Absorbency?
Medium
We're testing to see if organic material affects the water absorbency of soil. We'll measure how much water is absorbed by different mixtures of organic material and sand.
Hypothesis
The hypothesis is that 3/4 Peat moss will absorb the most water.
Method & Materials
You will measure out different amounts of organic material and sand, mix them together, add water, and measure how much water is absorbed after 12 hours.
You will need 2000 grams of sand, 750 grams of manure, 750 grams of peat moss, 7 plastic pots, 7 plastic spoons, 7 plant saucers, 7 liters of tap water, 1 measuring cup, and 1 triple balance beam scale.
Results
The results showed that 1/2 peat moss absorbed the most water in both trials, and 1/4 manure absorbed the least. This experiment showed that organic material does affect the water absorbency of soil.
Why do this project?
This science project is interesting because it can help gardeners determine which organic material will benefit their plants the most.
Also Consider
Experiment variations to consider include testing different types of organic material, such as compost or mulch, and testing different amounts of water.
