Investigate how microgravity conditions affect the rate of photosynthesis in algae using a clinostat to simulate a microgravity environment. This project explores fundamental biological processes in space-like conditions.
If algae are exposed to simulated microgravity conditions, then their rate of photosynthesis will decrease compared to normal gravity conditions.

Step 1: Set up the clinostat and ensure it functions correctly.
Step 2: Prepare algae cultures in Petri dishes with nutrient media.
Step 3: Divide algae samples into two groups: control and experimental.
Step 4: Place the experimental group on the clinostat to simulate microgravity.
Step 5: Expose both groups to identical light and temperature conditions.
Step 6: Measure the rate of photosynthesis using the spectrophotometer.
Step 7: Record CO2 levels with the CO2 sensor regularly.
Step 8: Compare photosynthetic rates between the control and experimental groups.
Step 9: Repeat measurements over a 4-week period.
Step 10: Analyze data and determine the impact of microgravity.
Step 11: Document findings and prepare your presentation.
Step 12: Conclude whether the hypothesis was supported by the data.
It is expected that the algae in the microgravity-simulated environment will show a reduced rate of photosynthesis compared to those in normal gravity conditions due to altered cellular processes.
