Can pH change the colors of the flowers around us?Plant Sciences
- Dr. Michael Frank
"Our project is testing how the color of a marigold’s (Tagetes erecta l.) petals changes based on the soil pH. We chose this project because it seemed like a good idea based on the criteria and it looked like an interesting project to carry out. Our overall conclusion was that as the pH of the soil got higher, the color of the petals got darker. Our project is important because it allows us to study plants in an intriguing way. It also helps us to make more scientific discoveries based on the levels of pH in plants and what it can affect throughout different species."
