Purpose: Problem: you want to see which is the better compost.Research: Compost is formed in nature all the time as plants and animals die and decompose. This natural compost is generally called humus. Decomposition involves the breakdown of plant and animalremains into simpler components.
.
Hypothesis: My hypothesis is that the compost will be good depending of how many water you include and it will not have airin the bottle for the food.
Materials: Fertilizer, green materials, such as grass clippings, green leaves, and vegetables and fruit scrapes; dried grass and leaves, twigs, straw, andsawdust; air and water.
.
Procedures: 1.Determine the problem: Consider the four ingredients necessary to make compost and state a problem about making an efficientcompost pile. 2.Make a hypothesis: Make a testable prediction about how the efficiency of a compost pile would be affected by varying the ratio of green to brown material, the amount of water added, andthe number of times a compost pile is turned (to supply oxygen). 3. Test your hypothesis: Click and drag the Brown to Green Balance bar, and the Water Concentration bar, and the Number of Turns bar tothe position you want to test. Click the Calendar. Click the Table button and record the combinations you tested and the resulting Efficiency Meter reading. 4. Click the Reset button and test othercombinations in the same way. Record your results in the Table. 5. Analyze your data: Use the table to analyze your data about the efficiency of the compost pile. 6. Draw a conclusion: Draw aconclusion about what combination of factors produces compost most efficiently.
