Water+Amounts

__The Problem:__ How do plants respond to the amount water given to them? __The task__ : The rate of plant growth is affected by how the plants needs are being met. Plants need the following in order to grow: air, nutrients, water, light, and space. How will plant growth change if you alter the conditions it grows in? 1. Choose a variable to investigate. 2. Determine your manipulated, responding, and controlled variables for your experiment. 3. Plant 4-5 of the same kind of seed in different containers. Use a couple of the trials as your ‘control’ group (under normal conditions) and a couple of trials as your ‘manipulated’ group. 4. Observe the plants over a period of weeks. Record your observations every 2nd day. __Hypothesis:__ I think that the plant with the most water will develop the best because it is getting more resources.
 * __Plant Investigation__ **

__Materials:__ __6 pots, 4 seeds, soil, water, and a measuring cup.__ __Variables:__ a. Manipulated: The amount of water b. Responding: __plant height__ c. Controlled: __same soil,__ __Shasta seeds, type of water, same type or pot, same sunlight.__ Procedure: 1. Put soil in plastic cup fill ¾. 2. Dig hole in soil of 2.5 cm deep 3. Put seed in hole 4. Cover up seed in soil 5. Do same for 5 more plastic cups 6. Measure water and pour in. 7. Put on same windowsill so that the plants get the right amount of sunlight. __Observations/Logbook:__ Day 1: Date: None of our plants germinated Plants were watered. None of them sprouted.

Day 3: Date: __None of our plants germinated.__ __Plants were watered.__

Day 5: Date: Plant germinated growing rate shown below Our control plant is 3 cm tall. Our plant are now starting to grow very rapidly. It is getting bigger very fast. We expect that our plant is probably going to have a growth spurt late because everyone else's has germinated and grew very tall.

Day 7: Date: __Our control plant is 11 cm tall__ __Our control plant grew 8 cm in 2 days and is growing steadily and very fast. It is still in the early stages of the life cycle.__

Day 9: Date: Over fall break our plants have died. We have to replant them and restart the process.

Trial 2. Day 1: We replanted the plants and watered them. Our hypothesis is kept the same for the second trial. No plants have germinated, they were watered.

Day 3: Still no plants have germinated, they were watered.

Day 5: The 15ml plant is poking through the dirt, it is 0.3 cm tall. I noticed the 20ml in our first trial was the first to grow, not the 15ml. All the other plants still haven't germinated.

Day 7: The 15ml plant is now 1 cm, still no other plants have germinated. Our hypothesis is incorrect so far for the second trial.

Day 9: The plants are growing rapidly the 15ml plant is now 16 cm tall and some leafs have sprouted. The 20 ml plant is now 12 cm tall and some of the leaves are just sprouting.

Day 12: The plants are still in their growth spurt and are growing very, very rapidly. The 15 ml plant is now 28 cm tall and the 20 ml plant is 25 cm tall. I think that the 15 ml plant is getting to much water and 20 ml is to much water for a bean plant.
