The hypothesis. To get this, you define a question, gather information, and decide upon your hypothesis.
The rest of the experiment follows.

Using the scientific method, a hypothesis must be tested as the focus of any experiment. A hypothesis is a specific, testable prediction about the relationship between variables. Through experimentation, observations, and data collection, scientists can support or refute the hypothesis, leading to conclusions that advance understanding of the topic. This process is essential for validating scientific theories and knowledge.

The factor not being tested in an experiment is called a control variable. Control variables are kept constant throughout the experiment to ensure that any changes in the outcome can be attributed to the factor being tested.
Variables that must be kept constant in an experiment are known as control variables. These variables are factors that can influence the outcome of the experiment, so keeping them constant ensures that any observed changes are due to the independent variable being tested.
The control in the lava lamp experiment would be a lava lamp that is not altered in any way and is used as a basis of comparison for the experimental lava lamp that is modified or tested. It helps to ensure that any changes or observations in the experiment are a result of the variables being tested, rather than external factors.
In an experiment, variables that must be kept constant are called control variables. Two common examples include temperature and pH levels. These variables should be kept constant to ensure that any changes observed in the dependent variable are a result of the independent variable being tested.
The control group in an experiment is not changed in any way. It is used as a baseline to compare and evaluate the effects of the treatments or interventions being tested in the experimental group.
