Light Intensity and Rate of Photosynthesis (Carol Cao)
Research Question and Hypothesis
Does light intensity affect the rate of photosynthesis in Elodea plants? Hypothesis: Yes, light intensity does affect the rate of photosynthesis. Too much light may cause plants to "burn out" while too little light will not provide enough light for optimal photosynthesis activity. Standards
Biology Standards
Students know usable energy is captured from sunlight by chloroplasts and is stored through the synthesis of sugar from carbon dioxide. Experimental Design
This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants. The rate of photosynthesis is determined by the number of bubbles formed by the Elodea plants. The
oxygen bubbles are a product of photosynthesis. Plants have shown to produce more bubbles when
placed closer to a light source than further away. The efficiency of photosynthesis can be measured
by the amount of oxygen bubbles formed during a given amount of time.
