• Go to the following Virtual Lab Website http://www.glencoe.com/sites/common_assets/science...
• The virtual lab runs under Flash. You may need to enable your browser to run it.
• Watch the short video clip about the white light spectrumand the pigments in plants.
• Using the controls to run the experiment, collect data to fill in the tables for radish and lettuce.
o Select the plant which will be planted in all pots, 3 pots per chamber.
o Select the color for each chamber.
o Turn the light switch “On” to run the experiment for a simulated 30 days.
o Use your mouse to grab the ruler and measure the height of the tallest part of the plant to the nearest centimeter. The height of each plant counts as one observation.
o Record the data in the appropriate data table.
o When you have recorded all three observations for a particular plant grown under particular conditions, calculate the average height of the plant under those conditions. To calculate the average, find the sum of the three observations, and then divide by three.
