Growing a bean plant is a simple science experiment that can be accomplished with a very little preparation. Additional variables can be used to expand the experiment. Determine how much sunlight is optimal by placing plants in sun, partial sun and dark to grow and measure the growth needs. Test the optimal amount of water needed or the best depth to plant at by changing these variables in the experiment.
- Clear plastic cup
- Potting soil
- Bean seed (2 per cup)
Using a clear plastic glass will allow students to better observe the growth of the roots. Plant the seed close to the edge of the glass for better viewing of root development.
Fill the cup three-fourths full of potting soil. If the experiment is testing other variables such as sunlight, water or temperature, fill enough cups for each variable. Create one cup for a control.
Press beans into soil approximately 1 inch apart to a depth of 2 inches for the control cup. Additional cups can be planted according to the variables being tested.
Water thoroughly and place in a sunny spot. Monitor beans for growth.
