The hypothesis is that plants will grow faster in a carbon dioxide-rich environment.

You will make your own carbon dioxide by combining baking soda and vinegar, and measure the growth of plants in the two environments.

You will need potting soil, two two-liter soda bottles with the tops cut off, four peat cups with seeds already germinated, two shallow dishes or paper cups cut in half, baking soda, white vinegar, a scale, a graduated cylinder, a thermometer, and a ruler.

The experiment showed that plants grew faster in the carbon dioxide-rich environment than in the normal environment. The temperature was also higher in the carbon dioxide-rich environment.

This science project is interesting because it shows how plants can use carbon dioxide to grow faster, and how global warming can affect plant growth.

Variations of this experiment could include testing different amounts of carbon dioxide or different types of plants.

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!!
