We know that plants need soil, water, and light to grow. Also that to little light, water, or soil can kill them same if there is to much. |
Research Question |
How does different amounts of water affect plant growth? |
Predictions |
The dry plants will all die from dehydration because they will eventually use up all the moister that is in the soil. The wet plants will grow some but then some of the plants roots might drown from to much water and the moist one will have the most amount of plant growth because it has the perfect amount of water. |
Experimental Design |
We will take three water bottles cut them in half then put dirt in the top half then plant 7 seeds in each one bottle being dry, another being moist, and the last one being wet. |
Conclusion |
My hypothesis was if there is a perfect amount of water then the plants will grow the most., which was correct. The moist plant grew the most by 1.31 average. The dry plants ended up dead because for three days in a row they had an average of 0. The plants that were in the wet soil were growing good then at the end they started dying. the averages of the wet plants went down 0.14 from the third day to the fourth day. So yes my hypothesis was correct. |
