Photosynthesis Lab
Question/Purpose:
The Question or Purpose of our lab is to answer the question “How is the germination of a seed affected by sunlight?”
Experimental Hypothesis:
We believe these results will occur.
1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water.
2. The seeds that are have a proper amount of water (10 mL of H2O a day) will grow the best and achieve the greatest height, and overall best appearance.
3. The seeds that are flooded with water (Kept at 100 mL of H2O per day) will grow the fastest at the beginning because they have the most water which …show more content…
What we are going to test on.
Petri dishes- Transparent glass cylinder which holds 100 mL of liquid. Used for holding seeds.
Paper towels- Corse paper which was greyish in color. Used for putting seeds on and cleaning up messes.
Water- Transparent liquid with no taste, odour. Used for giving nutrients to the beans.
Window with sunlight- Big glass open space in which the sun can reach our beans. Used for giving the beans energy and assisting in photosynthesis.
Ruler- Transparent piece of plastic which has marks for measuring. Used for measuring how much are beans have grown.
Eye droppers- Transparent plastic which holds 10 mL of water, transparent piece of glass with a black top holds about 5 mL of water. Used for adding water to our beans.
Tweezers- Silver metal pair of pincers. Used for picking up the beans to look at and measure.
500 mL beaker- A large transparent container which holds 500 mL of water. Used for transporting water from the sink to our beans so we could add water.
10 mL beaker- A small transparent container with groves to show how much water is in it holds 10 mL of water. Used for adding water to our …show more content…
With our beans that had a little amount of water (1 mL), there was almost no change in what happened they looked the same with an appearance of little wrinkles. They smelt the same and at day 8 they started to mold a little bit. The beans that had the moderate amount of water (10 mL), the beans started slow but ended up doing the greatest. They are the beans that grew the sprouts and started to smell like beans. The beans that were flooded started out the best and had the best potential. The beans had large cracks and split open, they slimed and ended up becoming so moldy that they had to be destroyed. They never sprouted even though they became the biggest. If the lab were changed and we put less water in the flooding petri dish than perhaps the beans would never have become so moldy and would have lasted longer and actually sprouted. The experimental design could be changed by multiplying the water levels by five times instead of ten. If that were to happen I believe that the beans with the moderate amounts would not end up doing the best because they are still not getting enough water. Since the beans that were flooded would only be getting 50 mL they would have a chance to grow the
