What are some examples of variables in science?

In science, variables are factors that can change in an experiment. For example, in a plant growth experiment, the amount of sunlight, water, and type of soil are all variables.

Can you explain the difference between independent and dependent variables?

Sure! The independent variable is the one that you change or control in an experiment, while the dependent variable is what you measure or observe. For instance, if you're testing how different amounts of water affect plant growth, the amount of water is the independent variable, and the plant height is the dependent variable.

What are controlled variables?

Controlled variables are the factors that are kept constant throughout an experiment to ensure that the results are valid. For example, if you're studying plant growth, you might keep the temperature and type of pot the same for all plants.

Can you give me an example of a scientific experiment with variables?

Absolutely! A classic example is testing how different fertilizers affect plant growth. Here, the type of fertilizer is the independent variable, the growth of the plants is the dependent variable, and factors like sunlight and water are controlled variables.
