To ensure that her experimental data is valid she should check every pH with a sample of algae. She should also write down all the data collected such as what happens when the pH changes and how much algea has grown at an specific pH. In addition, she should collect data multiple times to ensure that the replication of the experiment will result in the same data being obtained.

To validate her experiment on algae growth and pH, the student should use the same algae species, control other variables, replicate trials, randomize treatments, accurately measure growth, include a control group, and document all procedures. These precautions will strengthen her results and conclusions. Overall, careful experimental design is crucial for reliable scientific findings.
