Answer:
Independent variable is what you are testing in a experiment.
Dependent variable is what you're measuring in a experiment.
Explanation:
An example would be testing how fast plants can grow after two weeks of giving each plant a different amount of water.
The independent variable would be the plants. You are testing to see how fast the plants can grow depending on the amount of water you give each plant in a matter of two weeks.
The dependent variable would be the amount of water you give each plant. You are giving each plant different amounts of water each day in a span of two weeks to see which one will grow faster.
Hope this helps.
