01

Take a closer look

Green plants use light energy to build energy-rich substances from water and carbon dioxide. A comparison becomes more informative when we change one condition while keeping the others the same.

02

Now try it

  1. Plan a comparison of two similar plants under different lighting. Keep water, temperature and observation time as similar as possible.
  2. Create a table for daily observations. Record measurements separately from assumptions.

03

Think it through

Why should both plants receive the same amount of water?

See a suggested answer

Otherwise a difference might be caused by water rather than light. Keeping conditions the same helps investigate the effect of light.
