The hypothesis is that the roots of a germinated green bean will grow towards moisture.

You will need to fill 3 gardening pots with soil, plant 10 green beans in each pot, and water the pots daily for 5 days. Then, fill the porous cups in two of the pots with water and water the soil in the other pot for 10 days. After 10 days, remove the plants from the soil and observe how the roots have grown.

You will need 1 packet of green beans, 3 gardening pots, soil, a gardening spade, tap water, 3 porous cups, and a black marker pen.

The results showed that the roots in all 3 pots grew straight down, not towards the porous cup. This disproved the hypothesis that the roots of the germinated green bean will grow towards moisture.

This science project is interesting because it explores how plants respond to water in soil, and if they can sense where the water is located and start to grow towards it.

To vary the experiment, try using different types of seeds like corn seeds or soy beans. You could also repeat the experiment over a longer period of time to observe if the direction of root growth will change as the soil becomes drier.

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!!
