Nelson+Group+3

Nelson Rural: Tanner,Trevor,David, Hayleigh Purpose:Is to find out if non-disstilled water will have a slower growth rate than disstilled water.

Hypotheses: We think that the disstilled water will have a faster growth period.

Materials: -4 of the same sized bottles that are trans-parent. -4 of the same plants -Scissors -Alot of distilled water - rocks -hot plates' -rubber tubbing

Procedure: We chose to use one plant in normal water that was taken from our river and we have another bucket and if we used soil it would mix with the water and not be able to see through the bottle.So we chose to use aquarium rocks in the bottom of the 2L bottle.

step 1: get water from river step 2: Then distill water step 3: Then add 1200ml of water making sure the plant is covered step 4: Repeat steps 1,2 and 3 in another bucket.



Analysis:(pictures are also part of this part.) In this experiment we found that when we put two plants in polluted river water. Just like our hypothesis, the two plants died. fungus fourmed and the plants smell horrible.

Conclusion: When we went and did our experiment seeing if a plant would grow better in distilled water or in normal river water.As we checked in on the plants from day to day we noticed that the plant started getting brown spots on it and after 2 weeks the plants died and turned into a mushy substance and when the plant was in the distilled water the plant day from day didnt get brown spots but in 2 weeks it died to.So from what we noticed and we conclude that plants grow better in distilled water than river water.
