SCI 115 Week 3 Light Spectrum and Plant Growth

  

Instructions:

· Go to the following Virtual Lab Website http://www.glencoe.com/sites/common_assets/science/virtual_labs/LS12/LS12.html

· 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 spectrum and the pigments in plants.

· Using the controls to run the experiment, collect data to fill in the tables for radish and lettuce. 

o Select a plant

o Select the color for each chamber

o Turn the light switch “On” to run the experiment

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 Calculate the average height of the plant for each color.

QUESTIONS TO ANSWER

3. Based on these observations, which color of light causes the greatest amount of plant growth?

4. Based on these observations, which color of light causes the least amount of plant growth? 

5. In a short paragraph, explain how these observations are consistent with the information presented in the short video? 

6. Given that white light contains all colors of the spectrum, what growth results would you expect under white light?

Written Assignment: Biology and Technology in the Real World

 

Addresses course outcomes 1-4:recognize and explain how the scientific method is used to solve problemsmake observations and discriminate between scientific and pseudoscientific explanationsweigh evidence and make decisions based on strengths and limitations of scientific knowledge and the scientific methoduse knowledge of biological principles, the scientific method, and appropriate technologies to ask relevant questions, develop hypotheses, design and conduct experiments, interpret results, and draw conclusions

1. Select one of the topics listed below.

 

2. Find at least three information sources related to the topic. 

 

3. Write a 750-1500 word paper, excluding references and title page. You must read the information sources that you find and summarize the information in your own words, addressing each of the questions and expectations for your chosen topic. Extensive quotes from the article are discouraged. Use APA style for citing references.

 

 Topics (select one)

a) Genetically modified organisms (GMOs).  What is the purpose genetic engineering of crop plants and domestic animals? Briefly explain how GMOs are created. What foods in your supermarket contain GMOs? Are foods that contain GMOs safe for human consumption? What types of regulations exist for these foods? Clearly explain your reasoning for each answer. 

 

b) Stem cells.  Your friend had a spinal cord injury after a bad car accident. The medical team has decided that he is a good candidate for a clinical trial using stem cell therapy. Your friend has not had a biology course since high school, so you decide to write him a letter sharing your knowledge of stem cells. Include in your letter a description of the biology of stem cells and how these cells are unique from other cells. Contrast the different types of stem cells, including pros and cons of each. Explain how stems cells are can be used to treat diseases and injury, with special focus on spinal cord injuries. Conclude with your own opinion. 

 

c) Fracking (hydraulic fracturing) and tar sands (oil sands).   With society’s dependence on nonrenewable fossil fuels, the oil & gas industry is turning to the use of hydraulic fracturing and tar (oil) sands to extract natural gas and oil respectively.  A friend asks you “What’s all this controversy in the news about fracking and tar sands?”  Briefly explain to your friend how hydraulic fracturing and tar (oil) sands are used to obtain these fossil fuels. Then, in more detail, describe the environmental problems that may result from these processes and why they are controversial. Issues that may be addressed involves, but are not limited to, water, air and soil pollution, effects on human health, effects on other species and natural ecosystems. Finally, give your opinions on possible solutions to these environmental problems, with your reasoning backed by the references that you studied.

SCI115: Biology

“Tarnita’s Termites, Pacific Lampreys, and Large Brains”

This week our discussion is focused on animal evolution. For your primary post, respond to one of the following three topics. Also, please reply to at least one fellow student on any topic.

Topic 1 : Population Distribution of Termites in a Savanna. Watch the video (1) describing Corina Tarnita’s research on the spacing of termite mounds in savanna ecosystems, and then address the following: (a) What were Tarnita’s findings about the spacing of termite mounds?  (b) What does Tarnita think is the main factor that governs the spatial distribution of the termite mounds?  (c) How do the termite mounds benefit other organisms on the savanna?  

Topic 2 :  Pacific Lampreys. Watch the video about Pacific Lampreys (2)*, then address the following: (a) Where do Pacific lampreys fall in the taxonomy of vertebrates?   (b) What challenges do Pacific lamprey populations face?  (c) Why are Native American tribes of the Northwest concerned about them? (Please note: take care not to confuse the Pacific lamprey (described in the video) with the Sea Lamprey, which is a completely different species that is considered an invasive species in the Great Lakes).  

Topic 3 [article]: Supporting the Energy Needs of a Large Brain. As discussed in the article by Zimmer (3)*, brain tissue is energetically expensive. For a species to evolve a large brain, it may need to make certain adjustments to ensure that enough energy is available to support brain function. Zimmer discusses various hypotheses about such adjustments in the human line of descent. Explain one of these adjustments.
