Materials and Methods

MATERIALS NEEDED

40    Bean Sprouts
4      Plastic Containers
----   Cotton wool
----   Clean Water
----   Dilute Sulfuric Acid
2      Sprayers *(one for water and one for the sulfuric acid)

METHODS

Plant 40 bean sprouts, 10 in each plastic container. Each pot should be 1 quarter filled with wet cotton wool. Make sure that the bean sprouts are equally spaced apart and put all the pots in a cool, airy, filled with sunlight area indoors.

Water the plants with normal, clean water for 5 days for germination to take place. After the 5 day period, measure the plants height, colour of leaves and the stem and whether the plant germinated or not and write them in the "Before" column. **Take a picture of the plants from bird’s eye view and use preview to label them about what pot number, what treatment given to them [water (H2O) / Sulfuric Acid (H2SO4) ] and plant number. Print out the edited picture and put it beside the same pot for easy reference.

Start to spray the plants in 2 of the plastic containers with the dilute sulfuric acid for 1 week. At the end of the week, observe and record the height, colour of leaves, colour of stem and whether the plant germinated or not and record it down. Use a ruler to measure the height of the plant from bottom of the stem up and also calculate the change in height of the plants from before to after.

*LABEL THEM CLEARLY
**DO NOT CHANGE TOUCH THE POT AFTER TAKING THE PICTURE AS IT WILL ALTER THE RESULTS OF THE EXPERIMENT.
