2. Sunlight Vs. Grow Lab Light

3. Purpose Question: How long should we leave our grow lab lights on in order for our plants to get enough light to grow strong and healthy?

4. List four similarities and four differences between the sun and the grow lab.

5. Research: What is a Lux? A Lux is the measurement of actual light available at a given distance or how much it is illuminated. Illuminance is the intensity or how much something is illuminated and is not the amount of light produced by the light source. A Lux is a metric measurement, which measures square meters of illuminated surface area. Below are some examples of how many Lux are produced by different light sources. TV studios are lit at about 1,000 Lux A bright office has about 400 Lux of illumination At sunset and sunrise, ambient outdoor light is also about 400 Lux (if the sky is clear). moonlight represents about 1 Lux

6. Hypothesis: How many Lux do you think the following objects produce? (list your answers below) 1.Sun 2.Sunlight coming in through a window 3.Classroom light 4.Grow lab light.

7. Hypothesis: Based on your research how long should you we leave the lights on in our grow lab? Why do you think it should be that long?

8. Experiment: Testing different light sources to see how many Lux they produce. Materials: Light probe, sun, grow lab, classroom lights, sun through a window. Procedure: Follow the next few slides in order to complete the lab.

9. 1.First, take the light probe and point it at the classroom lights. 2.Then, click and let the probe run for 1 minute. 3.Last, click to stop the trail.

10. 1.First, point the probe at window which gets sun. 2.Then, click and let the probe run for 1 minute. 3.Last, click to stop the trail.

11. 1.First, go outside and point the probe at the sun. 2.Then, click and let the probe run for 1 minute. 3.Last, click to stop the trail.

12. 1.First, point the probe at the grow lab lights. 2.Then, click and let the probe run for 1 minute. 3.Last, click to stop the trail.

13. Analysis: Look at the data collected. 1.Place the four sources of light in order from most Lux to least amount of Lux. 2.How many more Lux does the sun through the window produce then the grow lab.

14. If your plants were in the window about how many hours of sunlight will your plants get? How did you come to that number?

15. Conclusion: Based on your research and observations how long should we keep our grow lab light on each day? Why did you pick that amount of time?
