||Plants can be trees, normal plants, and water plants. They carry seeds for the most part. They have leaves, bark, sap, and stems. Plants need Co2 which comes out as oxygen. Flowers have pollen which is pollinated by other insects such as bees which is the way that they reproduce.
I know that plants if they get too much sun it will dry up. Also, I know that plants can get too much h2o.
||Do different amounts of light affect the plants' growth? , One 1/2 covered, one full in sun, and one with so sun, and something with a lamp to see the difference of the plant.
||Our group thinks that the plants in the sun will grow quicker because we can move the plants into the procession we want and can make it grow the way we want. Also, the plant with the lowest amount of sun will grow the least because the plant needs the sun to grow.
||We are going to have 9 plants in total, 3 are alfalfa, 3 are pearl millet, and 3 are Rye grass. One of each of our plants is going to be in the sun all the way, 1/2 the way, and completely covered. We are going to see what plants will grow the best and what conditions. We hope to find which plant will grow the best in many different many ways. Our predictions were that The plant in the light will grow successfully and won’t have any problems. Our predictions are that the plant partially covered will still grow but it might aim itself more towards the sun eventually. We also predict that the embryo in the seed will react to the water and start to sprout but it will eventually die because it won’t be able to get sunlight. Our materials are Light, Boxes, 6 pots, 20 ryegrass seeds, 20 fern seeds, 20 pearl millet seeds, water, and masking tape. Our safety plans are to wash your hands after touching any part of the plant and not eat any part of a plant or seed used in the lab. Finally, our procedure is to first plant 2 of each of our plants, Ryegrass, Pearl millet, and Alfalfa with 10 seeds in each pot in potting soil. Nextly, to plant the Ryegrass we will divide the seed in half, rake the seed into the soil immediately, and then pour water on it immediately. Then, to plant the Pearl millet we need to make sure the soil is at least 65 degrees and the seed must be a ½ inch deep in the soil. To measure how deep the seed goes, we will dig and measure with a ruler how deep we dug. in addition, to plant Alfalfa we will put the seeds ½ an inch deep. Next, we’ll get a plant in the sunlight, a plant half covered by a box, and a plant fully covered by a box. In addition, over the days the plant is hopefully growing we will observe how the plant is growing. Then, When we get all our information we will check if our hypothesis was correct and document it. Furthermore, we will then state our conclusion about how the experiment went, some of the struggles we ran into during the experiment, etc. And finalize it. Finally, we will then make a poster stating our hypothesis, information, results, and conclusion.
||Our group experimented on which plant will grow the most in different amount of sun. Our group thinks that the plants in sun will grow quicker because we can move the plant into the procession we want and can make it grow the way we want. Also, the plant with the lowest amount of sun will grow the least because the plant needs the sun to grow. Are group found out are hypothesis was correct.
Some of the species of are data that showed are hypothesis was correct is the plants where turning yellow. ⅔ of the plants where yellow, and ⅔ of them were unhealthy, These plants where the plants in the no sun and ½ sun.
Are group thinks that the plants is the no and 1.2 sun are turning yellow and becoming unhealthy because the plants are not doing photosynthesis and not making chlorophyll and not making them green, so they are turning yellow and dying because they don't have sun for their cells. That's what we think the plants in no sun are growing the least, and the plants in the most sun are able to undergo photosynthesis and able to make chlorophyll and turning them green and making the plants have sugar for them to turn green and making them live and healthy.
We also think that the plants may have varied in growth and turned yellow because we did not water them considely. Some of the plants got 30 ml of water, well others got 50 ml of water. We also touched some of the plants when we were measuring them and they may have got the oils and other things and organisms from our hands on the plants. These different variants may have affected are experiment.
If we could do this project again, we would have a consistent amount of water in each plant, and have 3 plants for each plant. Like if we had a Rye grass plant in ½ covered. We would have 3 Ryegrass plants in the ½ covered instead of one. We would also have more than 3 plants in our experiment. We would do this because we can have more sources of data and we would be able to have more back ups if some would die. In the future we would like to see more different species of plants because we would like to see how different plants adapt to the no sun and ½ sun and how they would survive. Would they grow more? Would they die easier? That is the questions we would ask if we had different species of plants.
In conclusion. Are hypothesis was correct, we had data to show that are hypothesis was correct, and if did do this again, we would have made are amounts of water in each plant more confident, and would have more species of plants, and would have more plants for each species, like 3 plants in Rye grass in the ½ covered instead of 1. Besides are few flaws, are science experiment was a success and we learned a lot while doing this.
