Describe the experiments you performed. Alternatively, your teacher may have printed this document for you Site 2: Finally, students respond to a written prompt. Please visit these Virtual Lab Sites and complete the activities: Measuring the rate of photosynthesis in Elodea: Adjust the CO2 levels by clicking on the bottle.
You will count the number of bubbles at each level. The timer in the square box can be used to measure 30 seconds. The activity I am presenting is very wide open, and uses an inquiry instructional method.
Test each type of plant and use the ruler to measure the height. Which factors had a positive effect on the plant, which ones had a negative effect on the plant? What did you find out? At the end of the activity, the students present their findings to the class.
Your answer should be in a complete sentence. I am sure of the results and know my students will have data to analyze. Use data from the virtual labs to support your answer.
Make a hypothesis about which color in the visible spectrum causes the most plant growth and which causes the least plant growth. Determine the average amount of gas produced or plant height.
After the presentations, students form small groups to discuss the different topics presented. Propose hypotheses on how each of these variables effect the production of oxygen from a plant.
Collect data and write a summary of your findings that includes: Keep the light settings at white light you already tested colored light in the last experiment. Which abiotic factor s affect a plant? Remember, that when designing an experiment, you need to keep all variables constant except the one you are testing.
The purple slider can be used to change the light levels. The instructions are below: A Based on the light tests, as you increase the intensity of light, the rate of photosynthesis: My goal for this activity is to use the virtual labs ability to model what would happen if I had the time and place to do this lab in my classroom.
Use Question 1A to help you write this. I give them a set time to explore and collect data. Many of your tasks will be recorded in the journal which you will print out to turn in - there are 5 questions to answer in the journal, use complete, thoughtful sentences for each of these questions.
Glencoe Photosynthesis Lab "Which colors of the light spectrum are most important for plant growth? Create a data table use the ones above to help you and input values for at least 3 Temperatures. Which colors of the light spectrum are most important for plant growth?
Choose one variable and design and experiment that would test how this factor affects the rate of photosynthesis. I present the question to the students, and share with them the different virtual labs available to the students.
It will look similar. Collect data by changing the color of light. Find the optimal factors that cause the plant to grow the most. Take an average for each plant at each color. You already observed how light colors will affect the growth of a plant, in this simulation you can directly measure the rate of photosynthesis by counting the number of bubbles of oxygen that are released.Virtual Photosynthesis Lab.
Posted: Wednesday, December 10th, by Jeff Orlinsky. This month’s activity incorporates computer virtual labs into your curriculum.
I am not endorsing any company’s product; in fact you can find these labs via an Internet search. My goal for this activity is to use the virtual labs ability to model what. Keep your settings from 9c (25°C, light intensity of 20, increased CO2).a.
What were the bubbles per minute at this setting? _____ bpm b.
Now increase the temperature to 40°C. What were your bubbles per minute? In photosynthesis, plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds.
Critical to the process is chlorophyll, the primary photosynthetic pigment in chloroplasts. Photosynthesis Virtual Lab Site 1: Glencoe Photosynthesis Lab "Which colors of the light spectrum are most important for plant growth?" Site: ultimedescente.com (you can type "glencoe photosynthesis" into a google search to find this resource).
Study photosynthesis in a variety of conditions. Oxygen production is used to measure the rate of photosynthesis. Light intensity, carbon dioxide levels, temperature, and wavelength of light can all be varied.
Determine which conditions are ideal for photosynthesis, and understand how limiting factors affect oxygen production. Photosynthesis Virtual Lab.
