We know that for plants to go through photosynthesis they need water, carbon dioxide, and energy (sunlight). After they produce glucose and oxygen they go through cellular respiration. That requires glucose and oxygen. Cellular respiration produces carbon dioxide and ATP energy. Plants also contain cells and are most of the mass is made of water and carbon dioxide. Plant cells are the only cells that contain chloroplasts and cell walls.
Carbonated water is regular water with carbon dioxide gas that was dissolved into the water under pressure. Also known as carbonation. The bubbles are formed from the gas not dissolving. According to a study conducted at Colorado University Boulder, carbonated water makes plants grow faster and makes green plants grow greener. Sparkling water contains dissolved nutrients that are easily absorbed by the plants' root system.
Saltwater negatively affects plants by dehydrating them. Plants obtain water via their root system through osmosis. This osmosis is facilitated by cells around the hairs of the plant's roots that water passes through very easily. |
Research Question |
How do different liquids affect the growth rate of a plant? |
Predictions |
If we give plants carbonated water, then they will grow faster. |
Experimental Design |
Variables:
Independent Variable = Type of water
Dependent Variable = Plant growth
Variables to Control = Amount of sunlight
Materials: Containers for plants, different types of water, sunlight, seeds.
Procedure: Step 1 We are wrapping two seeds in a wet paper towel that has normal water on it
Step 2 We will put it in a container
Step 3 We will wrap two seeds in a different wet paper towel but this time there will be sparkling water on it
Step 4 After that we will put it in a container and see which one grows fast
Step 5 We will wrap two seeds in a different wet paper towel and this time it will be sugar water
Step 6 Then we will put it in a container and see which one grows fastest. |
