Photosynthesis Lab Report

Photosynthesis is the process by which plants and other organisms create energy. Light energy is converted into chemical energy that can be stored and used. CO2, water and light are converted into glucose and oxygen. The general chemical formula for this is, CO2 + H2O + light energy → Glucose + O2.
In this experiment, we will test the relationship between the rate of photosynthesis and the water consumed by the plant; we will be testing tap water–for a control, sugar water and salt water. If we test the rate of photosynthesis in sugar, salt and tap water, then sugar water will have the fastest rate because plants use sugar as fuel.
The experiment requires nine grams of baking soda, three grams of salt, three grams of sugar, liquid dish soap, spinach leaves, and water. The instruments needed are a plastic syringe, plastic cups, a stirring rod, a one-hole punch, a 100 mL beaker, a timer, and a scale. …show more content…
Use the scale to measure out one gram of baking soda. Mix the solution with the stirring rod. Then add a drop or two of dish soap. Second, use a one-hole punch to cut out 90 leaf disks out of baby spinach leaves. Try to avoid the stem areas and be sure that each cut out is a full circle. Take out the plunger from the plastic syringe and drop 10 leaf discs into the cylinder. Reinsert the plunger but make sure the leaf discs aren't damaged when you press
