Does Gravity Affect Plant Growth?

Easy
Does Gravity Affect Plant Growth? | Science Fair Projects | STEM Projects
Gravity affects the direction in which plants grow. To find out, we'll set up an experiment to see how the force of gravity affects the direction of plant growth.

Hypothesis

The hypothesis is that gravity affects the direction in which plants grow.

Method & Materials

You will set up a house plant on its side, soak some pinto beans, and place them on a spinning record player.
You will need a house plant, a few books, pinto beans, a glass, aluminum foil, paper towels, and a record player capable of 78 RPM speeds.

Results

The results showed that the roots of the beans on the spinning record player grew away from the center of the record player. This suggests that the force of the spinning record player on the root mimicked gravity, so the roots grew outwards away from the center of the record player.

Why do this project?

This science project is interesting because it shows how plants respond to the force of gravity.

Also Consider

Experiment variations to consider include testing different types of plants and different speeds of the record player.
