The hypothesis is that increased carbon dioxide levels will have a positive effect on plant growth.

You will germinate seeds in moist potting soil, create a chemical reaction to produce carbon dioxide, monitor the progress of the plant growth, water vapor, and temperature for one week, and compare the effects of CO2 to the control group.

You will need two large soda bottles with the top removed, two peat cups, a small cup or dish, several crop seeds, potting soil, 10 grams of baking soda, 20 ml of vinegar, and a thermometer.

The experiment showed that increased carbon dioxide levels had a positive effect on plant growth. The most notable observation was that the plants in the CO2 system grew faster than the plants in the control group.

This science project is interesting and unique because it shows how increased carbon dioxide levels can affect plant growth, and how this can contribute to global warming.

Consider experimenting with Elodea in a closed system such as a soda bottle with water. Try blowing into the container through a straw and compare the results to a sealed system.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
