The conversation between human and AI assistant.
What are controlled variables and what are some examples?
Can you give me an example of an experiment with controlled, independent, and dependent variables?
Sure! In an experiment testing the effects of fertilizer on plant growth, the controlled variables could include the amount of sunlight and water the plants receive, while the independent variable would be the type or amount of fertilizer used, and the dependent variable would be the height or number of leaves on the plants. By keeping the controlled variables constant, the scientist could more accurately determine if the fertilizer has a significant effect on the growth of the plants.
