Beyond the Answer

In an experiment, you change the independent variable. This is the factor that you manipulate to observe its effects on the dependent variable, which is the outcome you're measuring. For example, if you’re testing how different amounts of sunlight affect plant growth, the amount of sunlight is your independent variable! When designing your experiment, remember to keep all other factors constant, known as control variables. This ensures that any changes in your dependent variable are solely due to the tweaks you’ve made to the independent variable, leading to clearer and more reliable results.
