Science discipline

Goal: Students learn natural techniques to reduce carbon dioxide emissions

Objectives: Students will.

  • Understand the symbiotic relationship between plants and animals
  • Use chemistry to determine the how plants can help dissipate carbon dioxide


Materials Needed (per lab group or one set per class for instructor demonstration):

  • Cricket
  • Vernier CO2 monitor or similar probe
  • Graphing calculator (TI 83 or similar) that interfaces with probe or computer with appropriate software for probe
  • Graphing calculator projection system or computer projection system if class demonstration
  • Any cords or adaptors that may be necessary depending on set-up
  • Small glass bottle with a one-hole stopper to insert probe through
  • Small plant that will fit into bottle
  • Sunlight or small lamp
  • Graph paper for each student
  • Student Response Sheet for each student
     

Time: Two 45-60 minute periods

Standards Met: M1, M2, M3, S1, S2, S4, S7

Procedure:

  • Load any software on computer or graphing calculator that came with the probe.
  • If a class demonstration, set-up projection systems.
  • Place the cricket in the small bottle and seal tightly with probe through stopper.
  • Run the graphing program that is supplied with the probe and observe the change in CO2 in the bottle for 30 minutes.  Have the students construct similar graphs on their graph papers.
  • Repeat the experiment with the small plant added to the bottle. Make sure that you supply the same lighting conditions for both tests.
  • Clean up your equipment according to your instructor's directions and answer the questions on your Student Response Sheet.

The Cricket and The Plant-Teacher Sheet

Introduction and Teacher Background: Carbon sequestration in terrestrial ecosystems is either the net removal of CO2 from the atmosphere or the prevention of CO2 net emissions from the terrestrial ecosystems into the atmosphere.

Enhancing the natural processes that remove CO
2 from the atmosphere is thought to be one of the most cost-effective means of reducing atmospheric levels of CO2, and forestation efforts and deforestation abatement efforts are already under way.

Techniques for Reducing Carbon Emissions

Forest lands.
The focus includes below ground carbon and long-term management and utilization of standing stocks, under story, ground cover, and litter.

Agricultural lands. The focus includes croplands, grasslands, and rangelands, with emphasis on increasing long-lived soil carbon. 

Biomass croplands. As a complement to ongoing efforts related to biofuels, the focus is on long-term increases in soil carbon.

Deserts and degraded lands. Restoration of degraded lands offers significant benefits and carbon sequestration potential in both below-and above ground systems.

Boreal wetlands and peat lands. The focus includes management of soil carbon pools and perhaps limited conversion to forest or grassland vegetation where ecologically acceptable.

Using a CO
2 monitor, students will measure the output of CO2 from a cricket in a closed environment. They will then repeat the experiment with the addition of a small plant.

The Cricket and the Plant - Student Sheet

Follow the steps below to complete the lab.

  1. Get the lab supplies.
  2. Place the cricket in the small bottle and seal tightly with probe through stopper.
  3. Run the graphing program that is supplied with the probe and observe the change in CO2 in the bottle for 30 minutes OR Construct graphs on graph papers, taking readings once every minute for 30 minutes.
  4. Add the small plant to your bottle.
  5. Repeat the experiment with the small plant added to the bottle. Make sure that you supply the same lighting conditions for both tests.
  6. Clean up your equipment according to your instructor's directions
  7. Answer the Questions for Thought on your Student Response Sheet.

Carbon Cycle

carboncycle

Background:
The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate (see diagram above). The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago produced carbon dioxide, which through photosynthesis, became part of a plant. When you eat that plant, the same carbon from the wood, which was burnt, can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately, the extent of its importance is rarely stressed enough. Without the proper functioning of the carbon cycle, every aspect of life could be changed dramatically.

Scientists believe that it's vital to understand how the carbon cycle works in order to see the danger of it not working. In this activity, we will examine a small part of the carbon cycle and explore how carbon atoms move through it.

Plants and animals interact to make up the basic cycles of nature. In the carbon cycle, plants absorb carbon dioxide from the atmosphere and use it, and combined with water they get from the soil, make the substances they need for growth. The process of photosynthesis incorporates the carbon atoms from carbon dioxide into sugars. Animals, such as the cricket, eat the plants and use the carbon to build their own tissues. These crickets then return carbon dioxide into the air when they breathe (the process of respiration), and when they die, since the carbon is returned to the soil during decomposition. The carbon atoms in soil may then be used in a new plant or small microorganisms. Ultimately, the same carbon atom can move through many organisms and even end in the same place where it began. Herein lies the fascination of the carbon cycle; the same atoms can be recycled for millennia!

  1. What accounted for the increase in CO2 during the first part of the experiment?  Explain your answer fully.




     
  2. Why didn't the CO2 increase in the second part of the experiment?




     
  3. You might call the small bottle in the second part of this experiment a "balanced" ecosystem in relation to O2 and CO2.  Draw an illustration below that show how these gases are exchanged in this system.




     
  4. Explain how planting more trees or limiting deforestation can decrease the amount of CO2 in our atmosphere.




     
  5. What can you do as an individual to limit the amount of CO2 in our atmosphere?

 

The Cricket and the Plant- Teacher Answer Key

  1. What accounted for the increase in CO2 (Carbon Dioxide) during the first part of the experiment?  Explain your answer fully. 

    The cricket, through respiration, produced carbon dioxide, which increased the amount of the gas in the container.
     
  2. During the second part of the experiment, what happened to the production of the CO2

    In the second part of the experiment, some of the carbon dioxide produced by the cricket was used by the plant during photosynthesis. Therefore, the total amount of carbon dioxide did not increase as much as it did in the first experiment.
     
  3. You might call the small bottle in the second part of this experiment a "balanced" ecosystem in relation to O2 (Oxygen) and CO2.  Draw an illustration below that shows how these gases are exchanged in this system.

  4. Explain how planting more trees or limiting deforestation can decrease the amount of CO2 in our atmosphere.

    Plants use carbon dioxide during photosynthesis, the more plant (trees), the more carbon dioxide that will be removed from the atmosphere.
     
  5. What can you do as an individual to limit the amount of CO2 in our atmosphere? 

    Stop exhaling (not serious). The production of energy releases large amounts of CO
    2 into the atmosphere.  As an individual, conserving energy would help limit the amount of CO2 in the atmosphere.
