How does the amount of salt in water affect the growth rate of certain plants?
We predict that the plants that are watered with fresh water will grow faster. We think this because…
Brassica Seeds (Ms. Lemus)
Radish Seeds (Ms. Lemus)
Cucumber Seeds (Ms. Lemus)
Water (Sink at School)
Planting Containers (Store)
6. Water the other half of plants with salt water (use ¼ of a cup in water in each)
Measure height and circumference
Take a picture of each plant
9. Water the plants every other day
10. Repeat Steps 5-9 for 1 month or until our hypothesis is made clear
