Procedure

1. One week before you do your experiment, you have to test if the beans will actually germinate.

2. Take ten Pinto beans and a wet paper towel.

3. Lay the beans spread out on one half of the paper towel and fold the other half over the half with the beans.

4. Put the paper towel in a Ziploc bag and check back on them in 5-7 days. If they have roots coming out, they are good to use for your experiment.

5. To get the tap water, go to the sink and use water from there.

6. To get bottled water, go to the water cooler or use water from plastic bottles.

7. To get recycled water from the washing machine, after the first spin cycle of the washing machine, it fills up with water a second time.

8. After it fills up, open the washing machine and take the container and take water out.

9. Separate 90 pinto beans into three piles, 30 in each pile, one for tap water, one for recycled water, and one for bottled water.

10. Take out seed starter pots and put them where the plants will be able to get sunlight.

11. Fill each section in the seed starter pots around ¾ full and then put the seed halfway down in the dirt and cover the seed back up with dirt.

12. Give each plant one inch of water (recycled, bottled, or tap depending on which section you're watering) every other day.

13. Measure each plant with a ruler and write down the height of each plant (in cm).

14. As the plants grow taller they may start to bend over and will need support. To do this, take one of the wooden skewers and stick it in the ground next to the plant.

15. Wrap the plants around the skewer and tie an 8inch long piece of yarn around the stem of the plant.

16. And more dirt to the base of the plant and skewer to add more support.
