Do Detergents Affect Plant Growth? | Science Fair Projects | STEM Projects
In finding ways to recycle water, have you ever wondered if it's ok to water plants with detergent water? Let's do this experiment to find out! We'll use the same type of plant and three different types of detergent to see what happens.

Hypothesis

The hypothesis is that the detergent will affect plant growth and kill the plant.

Method & Materials

You will need four of the same plants in little pots, three different types of detergent, and an area with sufficient sunshine. You will water the first plant and let it stay, then mix half a cup of detergent with half a cup of water and pour the mixtures in each of the remaining three plants. Record your results after seven days.
You will need four of the same plants in little pots, three different types of detergent, and an area with sufficient sunshine.

Results

After testing for seven days, the experiment showed that the three plants that were watered with detergent water died. The plant that didn't have detergent in it lived and was in good condition. This observation stands out because it shows that detergent can be poisonous to plants.

Why do this project?

This science project is interesting because it shows how detergent can be poisonous to plants.

Also Consider

Experiment variations to consider include testing different types of detergent or different amounts of detergent.

It's interesting to think that something as simple as adding detergent can make a difference in the growth of plants! This student's project shows that detergents can help radish seeds grow into strong and healthy plants. It's exciting to think about what other experiments we can do to explore this finding further and discover why detergent affects plant growth!
