Plant Growth

Students Ethan Wong and Taylor Church are studying plant growth. They are growing plants under various conditions to determine how it affects the plants. They are keeping temperatures and nutrients the same, but are varying the color of light and the air quality the plants are exposed to.

Ethan (left) and Taylor set up a chamber that will study air quality.

The control chamber using regular light and air. A control is necessary to see how changing the light and atmosphere makes the plants different from a "normal" plant.

The light chamber. Ethan and Taylor chose a reddish light because when we live on Mars, the sky will be approximately that color.
