State The Problem: Does salt water effect plant growth
Gather Info: Salt water affects plants by dehydrating them. Salt water also affects plant by stunting there
growth. The affect that the salt water has on plants depends on how much salt water is in it.
Hypothesis: I think the salt water plant will die and the regular water will be just fine.
Experiment Steps:
1. you get 4 cups
2. you get the lima bean
3. you get the plastic wrap
4. you get the paper towel
5. After that you put some salt and water in one of the cups
6. Then you label the salt water cup
7. then you get another cup and put just regular tap in the cup
8. then you label the tap water cup
9. you get the two other cups and sit them down beside you, you will need them in a second
10. You get the lima bean and you wrap the lima bean in the paper towel ( tip: leave the lima bean a little bit out so it can get some sun)
11. then you wet the paper towel that has the lima bean in it
12. then you put the lima bean with the paper towel wrapped around it in a cup
13. Poor out the remaining water from the cup
14. after that you do the 10th, 11th and 12th step again with the last cup ( but you use tap water instead of saltwater)
15. Then you put the cups with the lima beans in them by your window seal so your bean can get sunlight to grow
16. Then check your lima beans every day to see the results
