Unformatted text preview: Name:____________________________________________ Date:__________ Journal Questions 1. Make a hypothesis about which color in the visible spectrum causes the most plant growth and which color in the visible spectrum causes the least plant growth? if the red light shins on the plant then it will grow because the chlorophyll absorbs red wave lengths, if green light shines on the plat it will not grow as much because the chlorophyll reflects green. 2. How did you test your hypothesis? Which variables did you control in your experiment and which variable did you change in order to compare your growth results? i tested my hypothesis by using different lights on different plants. in the experiment we make the amount of light stay the same but changed the plants be did the experiment on to compare the results. 3. Analyze the results of your experiment. Did your data support your hypothesis? Explain. If you conducted tests with more than one type of seed, explain any differences or similarities you found among types of seeds. the data i got from the experiment showed that blue worked the best but it was also correct because i said that the green would not work as good as the others 4. What conclusions can you draw about which color in the visible spectrum causes the most plant growth? the plant can also absorb blue light and that is why it work so well. 5. Given that white light contains all colors of the spectrum, what growth results would you expect under white light? white light will work the best because it will absorb red orange yellow blue and purple light. so the plant will grow faster.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
