||We all know that plants heavily depend on water and sunlight to survive. Last year we all learned that plants are responsible for photosynthesis which is the process of inhaling CO2 and then turning it into oxygen. In this class, we discovered that the mass of a plant comes from the carbon inhaled by the plant.
||Where exactly does the mass from the seeds come from? How do they inhale the carbon?
How does a gas make a seed heavier? Don't you think it was the water that the seeds get the mass from?
||we think that plant number 1 one will have more mass than the other two plants because its being placed in the sunlight and it is being watered. since the mass of the plant comes from the carbon outside, the plant that is placed inside a cabinet will hardly have any mass, and the plant that is not being watered we think it will dry out.
||Step 1: gather materials needed
Step 2: place a paper towel in each petri dish
Step 3: place one gram of seeds in each dish
Step 4:take dish one water it and place it by the window.
Step 5: take dish two and water it and place it on a dark cabinet.
Step 6: place dish 3 by the window.
Step 7: wait 1-2 weeks
Step 8:place dishes in drying oven
Step 9: weigh the mass
Step 10: record data
Step 11: show your results in a graph
