X-Rays and Plant Growth

X-Rays and Plant Growth | Science Fair Projects | STEM Projects
Ever wondered what happens when you expose green beans to X-rays? In this project, you'll find out if X-rays can stop green beans from growing.

Hypothesis

The hypothesis is that overexposure to X-rays will cause tissue damage and prevent green beans from germinating.

Method & Materials

You will expose green beans to X-rays and measure the height of the bean sprouts.
You will need an X-ray machine, 40 green beans, 4 pots, soil, a ruler, and water for the plants.

Results

The results showed that the green beans that were exposed to X-ray for 100 seconds did not germinate. However, the green beans that were given 1 second of X-ray exposure germinated and grew more quickly than the control beans without any radiation exposure.

Why do this project?

This science project is interesting because it shows how ionizing radiation can affect plant growth.

Also Consider

Experiment variations could include using radiation from an ultraviolet lamp or trying other plant seeds like tomato, chili or sunflower.
