to have something to compare with the growth of fertilized plants
An important part of planning an experiment is defining clear objectives and hypotheses. This helps guide the experiment design, data collection, and analysis to ensure relevant and meaningful results are obtained.
without a hypothesis there is no experiment
It seems like there may be a typo in your question. If you meant "results," then it typically refers to the outcomes or findings obtained from a process, experiment, test, or investigation. Results can provide valuable information and insights to help guide decisions or actions.
The lava lamp experiment involves mixing water, oil, food coloring, and an effervescent tablet (like Alka-Seltzer). The tablet creates gas bubbles that rise through the oil and water mixture, carrying colored water with them. There is no specific equation for this experiment, as it is a simple chemical reaction that creates a visual effect. Just follow the steps in the experiment guide to create your lava lamp.
To form a hypothesis on making borax crystals, you could propose a statement that predicts the outcome of the experiment based on your understanding of the process. For example, your hypothesis could be: "If I dissolve borax in hot water and allow it to cool slowly, then I predict that larger crystals will form compared to when the solution cools quickly." This hypothesis can guide your experiment and help you determine if your prediction is correct.

Controls are not needed in the arthropods experiment because the study does not involve comparing treatments or conditions. The purpose of the experiment is simply to observe and describe arthropods in a specific environment, rather than testing a hypothesis or comparing experimental groups. Controls are typically used when comparing treatments to ensure any observed effects are due to the treatment itself and not other factors.

Controls are not needed in the arthropods experiment described in the study guide because the purpose is to observe the natural behavior or characteristic of the arthropods in their environment without any manipulation or comparison with a control group. This type of observational study does not require controls to assess the behavior or traits being studied.
