1. I decided to measure the oxygen released during photosynthesis because it is a common byproduct of the process and can provide a quantifiable measure of photosynthetic activity.
2. Data is necessary in an investigation to provide evidence and support or refute hypotheses. It allows for the comparison of different variables and the identification of patterns or trends.
3. The data collected during the investigation did not prove the hypotheses, as there was no significant difference observed between the control and experimental groups. However, it did provide valuable information about the photosynthetic activity of the plants under different conditions.
4. Scientists need evidence to support a hypothesis because it adds credibility and validity to their claims. It allows others to replicate the study and verify the results, ensuring that the conclusions are based on solid evidence.

Think about the investigation you have chosen to conduct or refer to the sample investigation. Write a short report that covers all the parts of your portfolio activity. Imagine that you are a real scientist, and you want to show your results to a journal that is reviewed by other scientists.Think about what you learned in the lessons, and write a short sentence describing what each term you wrote is used for. Use your word cloud list to answer these questions:1. How did you decide to measure the oxygen released during photosynthesis?
2. Why do you need data in an investigation?
3. Did your data prove your hypotheses?
4. Why do scientists need evidence to support a hypothesis?
Think about the scientific method, and what you used to plan, conduct, and report your investigation. Imagine you are going to make a word cloud using key words to show the steps you took to conduct your investigation. Make a list of the words you would put in your word cloud.
