Science 2019

Project by group dmsgrayspring2019

Explore All plants have cells, in the cells they have chloroplast, which perform photosynthes. They need photosynthesis to survive. Plants start as seeds underground. When they are under ground they do not have access to everything they need to perform photosynthesis. To make there food or glucose they need sunlight, carbon dioxide, and water. While under ground they go through the process of germination the reach sunlight.
Research Question How does the amount of water given to a corn seed effect how long it takes to germinate?
Predictions If you increase the amount of water given to a corn seed then the amount of time it takes to germinate will also increase because seeds need water to live and grow so the more water it has the faster it will grow.
Experimental Design First assemble 3 growth chambers (bottles base) Have bottle one with no water, bottle two with a little water, and bottle three with a lot of water. Next check to see if any plants have germinated. Record data.
Conclusion In a seeds first stage of life it uses its stored food to live. But the seed has to germinate so it can grow and go through photosynthesis to live. A seed needs 3 things to germinate, water, warm temperature, and good soil. If water is a necessity for seeds to germinate then if seeds get enough it will germinate faster. This is what I expected.
