The Effect of Water Hardness on Seed Germination
Medium

Do you want to know if watering plants with soft water helps seeds germinate faster? In this science project, you'll find out by testing the germination of seeds in hard, tap, and soft water.
Hypothesis
The hypothesis is that watering plants with soft water will help seeds germinate more quickly.
Method & Materials
You will label three beakers as "Hard", "Tap", and "Soft". Place 20 seeds in each beaker, and fill each beaker with 200ml of water. The "Hard" beaker will have 5mg of calcium added, and the "Soft" beaker will have 10ml of water softener added.
You will need 1 packet of black-eyed Susan seeds, 3 large beakers, 3 balls of cotton, 10ml of water softener, 5mg of calcium, tap water, 1 measuring cylinder, and 1 black marker pen.
Results
The results showed that the rate of seed germination was almost the same for all types of water used. This disproves the hypothesis that watering plants with soft water will help seeds germinate more quickly.
Why do this project?
This science project is interesting because it tests the effect of water hardness on seed germination, which is an important factor in plant growth.
Also Consider
Variations of this science project could include testing different types of plants, or testing the seeds in different environments such as under the sun, in a shaded area, or indoors.
