Lemon Juice vs. Water

Problem- Can I use lemon juice to water my plants and grow the plant better then when I use water?

Background Knowledge-Most people water there plants with water. A lemon is a citrus fruit. The bean is from the leguminosae family. A bean is a seed.

Hypothesis- I predict the lemon juice will not make the bean plant grow better then water.

2 beans
lemon juice
graduated cylinder
2 cups
measuring cup

Method-Step 1. Go get your lab coat and goggles.
Step 2. Put your lab coat and goggles on.
Step 3. Get 2 beans and 2 cups.
Step 4. Put your name on both cups.
Step 5.Take your 2 beans and go weigh them.
Step 6. Then take your your 2 cups and put equally amounts of soil in them.
Step 7. Make a hole half way through the soil in both cups.(bout the width of your pinkie)
Step 8. Then, drop 1 bean in each hole, gently cover the bean with soil.
Step 9. Then, go get 10mL of water in a graduated cylinder.
Step 10. Pour the 10mL of water in one of the cups.
Step 11. Then, go get 10mL of lemon juice in a graduated cylinder.
Step 12. Pour the lemon juice in the other cup that has no water in it.
Step 13. Rinse the cylinders you used out and lay them out to dry.
Step 14. Write on the cups which one has the lemon juice and which one has the water in it.
Step 15. Lay your cups on the table Mr. Mayher has set up.

Collect Data- Made a graph

Conclusion- Since the plant watered with water grew more then the plant watered with lemon juice you could conclude that the citrus( or whatever else was in the lemon juice) can keep the bean plant from growing.

Questions to extend project-Could a bean plant watered with lemon juice grow faster than salt water? Can using manure make a bean plant grow faster than using regular soil?
