Dana is reading about the best conditions for worm composting. Worm composting involves keeping worms in a bin with vegetable scraps from the kitchen along with other plant waste, and using the soil and drippings they produce to improve gardens.

What should she do?

Here are your answers

A.She should test the variables all at once in three different bins with the same amount of worms.
B. She should test the variables one at a time by keeping two of the variables constant and testing the third.
C. She should test the variables at the same time by keeping one of them constant and testing the other two.
D. She should test a different variable in the same bin over the course of a week, allowing two days for each variable.

im not sure if its b or c pls help

To determine the best conditions for worm composting, Dana can benefit from a systematic approach. Both options B and C involve testing the variables one at a time while keeping some variables constant. Let's break down both options:

Option B suggests testing the variables one at a time by keeping two of the variables constant and testing the third. For example, Dana could keep the amount of worms and the type of vegetable scraps constant while varying the other variable, such as the plant waste. By observing the results, she can determine the impact of the varied variable on the worm composting process.

Option C suggests testing the variables at the same time by keeping one of them constant and testing the other two. In this case, Dana could keep one variable, such as the amount of worms, constant while varying the other two variables, such as the type of vegetable scraps and the plant waste. Again, by observing and comparing the results, she can evaluate the impact of each variable on worm composting.

So, both options involve systematically testing the variables while keeping some variables constant. The difference between them lies in the starting point of keeping one constant and varying the other two (Option C) or keeping two constant and varying the third (Option B).

Ultimately, the choice between option B and C would depend on Dana's specific goals, available resources, and preferences. She should consider factors such as time, budget, and desired level of detail in her experimentation before deciding on either option B or C.

Based on the information provided, the most appropriate approach for Dana would be option B: She should test the variables one at a time by keeping two of the variables constant and testing the third.

By keeping two variables constant and testing one at a time, Dana will be able to accurately assess the impact of each variable on worm composting. This method allows for a clearer understanding of cause and effect relationships between the variables being tested.
