Photosynthesis Virtual Lab - Biology

Follow the Procedure to complete the Lab

Procedure:
1. Click the Video button. Watch the animation to learn how light is made up of many wavelengths.
2. Make a hypothesis about which part of the light spectrum causes the most plant growth and which part of the light spectrum causes the least plant growth. Assume that all conditions (soil content, moisture availability, and seed viability) are the same for each seed as it grows. The only variable is the color of the light. State your hypothesis in the Journal.
3. Test your hypothesis by choosing different plant seeds and observing how the plants grow under different colors of light.
4. Choose the type of seed that you want to test and click its seed packet.
5. Click the arrows on the color display to select a color light filter for each set of three plants.
6. Start the experiment by clicking the light switch to the On position.
7. Observe the plant growth.
8. Click the ruler and drag it to each plant to measure the height. Use the calculator to average the heights of the three plants under each color light filter. Record your calculations in the Table.
9. Click the Reset button. Repeat the experiment using a different color light filter and the same type of seed. Click Graph to see the results of your experiment.
10. After all color filters have been tested on one type of seed, conduct the experiment again with another type of seed to verify your conclusions. Complete the Journal questions.
