Last year, we investigated the growth of lettuce seeds with different nutrients added to the soil. We noticed that the plants with added chicken manure barely grew. We hypothesized that the plants couldn’t break down the nutrients. As a result, this year we decided to put the nutrients in water to make them easier to break down. In our investigation, we tested to find out how different nutrients in water would affect the growth of lettuce seeds.

  1. A really good question. Your explanation of your method was really helpful. I hope you will come back with more studies of this important question
