Do different colors of light affect plants differently?
My experimental purpose was to determine if the color of light affects the amount of oxygen created through the process of photosynthesis by elodea, a type of aquatic plant.
What side of a plant's leaf takes in atmospheric gases?
Ten (10) students say the top of the leaf takes in gases because when rain and watering cans water plants it comes from above and hits the top of the plant leaves first. Ten (10) say the bottom of the leaf takes in gases because after observing the leaves from each plant the bottom of the leaves were more veiny and the skin of the bottom leaves seemed thinner. The top of the plant leaf had a t
Prove increased starch increases the process of photosynthesis in the green plant.
To measure the amount of starch left in a leaf of a geranium plant under the following conditions; carbon dioxide increased, decreased and neither increased or decreased.
The effect of Different Light Wavelengths on Photosynthesis
Light energy is the key to photosynthesis. A relatively narrow portion or the visible light spectrum is most active in photosynthesis. By performing experiments that selectively filter out different wavelengths of light you can learn about which wavelengths are most active in driving photosynthesis.
Aquatic plants and animals and the acidification of our oceans
This experiment was performed to ascertain the effect of aquatic plants on the acidity levels of our oceans. Carbon dioxide levels in our atmosphere have been on the rise mainly due to the burning of fossil fuel and deforestation. The results of this experiment will ascertain whether aquatic plants help to reduce the acidification of our oceans, via the process of photosynthesis.
What are the conditions necessary for seed germination?
The following experiments with plants can be used progressively through the plant units in the K-6 science curriculum. They are all based upon growing seeds in a sterilized baby food or Snapple ® jar filled with 3/4 inch of unflavored gelatin to which a few drops of liquid house plant fertilizer has been added for nutrients.
How does acid rain affect seed germination?
The purpose of this experiment was to determine the effect of acid on seed germination. I became interested in this idea because I know that acid rain is becoming a factor in pollution around the world. I know this from books I've studied and news articles Iíve read
What is photosynthesis and do plants need sunlight to photosynthesize?
Of all the organisms in the natural world, green plants are the only ones that manufacture their own food. This process is called photosynthesis and begins when light strikes the plant's leaves (both sunlight and artificial light can power this process). Cells in the plant's leaves, called chloroplasts, contain a green pigment called chlorophyll which interacts with sunlight to split the water
How does temperature affect the rate of growth of algae?
The purpose of this experiment was to determine the effect of a certain species of algae when they are growing at different temperatures.
Do plants grow faster when grown hydroponically instead of in soil?
The purpose of this experiment was to determine in which condition plant shoots grow roots best: the conditions were in chemical solution, tap water, and soil.
