Standards:

Academic Expectations –

2.2 Students identify, analyze, and use patterns such as cycles and trends to understand past and present events and predict possible future events.

2.3 Students identify and analyze systems and the ways their components work together or affect each other.

Program of Studies-

S-HS-LS-2 Students will investigate cell regulation, differentiation, and how the process of photosynthesis provides a vital connection between the Sun and energy needs of living systems.

S-HS-LS-8 Students will analyze energy flow through ecosystems.

S-HS-LS-11 Students will recognize that living systems require continuous input of energy.

S-HS-LS-12 Students will investigate photosynthesis, cellular respiration, and the energy relationships among them.

Core Content-

SC-H-3.1.5 Plant cells contain chloroplasts, the site of photosynthesis. Plants and many microorganisms (e.g., Euglena) use solar energy to combine molecules of carbon dioxide and water into complex, energy-rich organic compounds and release oxygen to the environment. This process of photosynthesis provides a vital link between the Sun and energy needs of living systems.

SC-H-3.5.2 Energy flows through ecosystems in one direction from photosynthetic organisms to herbivores to carnivores and decomposers.

SC-H-3.6.1 Living systems require a continuous input of energy to maintain their chemical and physical organization since the universal tendency is toward more disorganized states. The energy for life primarily derives from the Sun. Plants capture energy by absorbing light and using it to form strong (covalent) chemical bonds between the atoms of carbon-containing molecules. These molecules can be used to assemble larger molecules (e.g., DNA, proteins, sugars, fats). In addition, the energy stored in the bonds between the atoms can be used as sources of energy for life processes.

Culminating Performance

Read the attached article “Power Plants”. As an astronaut living on a space station on the moon, how can you help to create an atmosphere that would support life?

Write an open response that would indicate the changes necessary to help create an atmosphere that contains oxygen. Are there any flaws to this theory? Would this task be possible?

Culminating Performance Rubric:

4. The student shows the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They also SEE the flaws associated with this thinking because of the lack of CO2 and H2O and the lack of sufficient gravity in order to maintain an atmosphere. The student uses correct grammar throughout with logical scientific thinking skills.

3. The student shows the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They understand that simply planting green plants may not work but their ties to gravity & atmosphere are not evident. They may have a few grammatical errors but it does not take away from the reading.

2. The student shows the relationship between the need for plants to undergo photosynthesis in order to generate oxygen but they are not able to SEE that the lack of atmosphere and insufficient gravity will limit life on the moon. The student may have several grammatical errors.

1. The student has a lack of understanding concerning photosynthesis and oxygen production. They made an attempt to answer the question but their lack of understanding limits their ability to answer the question. They may have grammatical errors but those are not as relevant as the main focus of the paper.

PROCEDURES:

Beginning Review:

Review of the processes of cellular respiration and photosynthesis via the equations so they can visualize the formulas and that they are reversible. The class will check the homework crossword puzzle and review this for accuracy.

Anticipatory Set:

The following questions will be asked to the class, prompting a discussion:

What happens when oxygen is not available to the cells?

Do the cells die?

What about those organisms that do not require oxygen?

How do they make energy from food?

What are some organisms that you know are anaerobic? (bacteria, yeasts)

Concept Development:

The students will receive information via media projector and computer PowerPoint presentation. Students will receive information on Lactic Acid Fermentation and how the cells use this process when oxygen is depleted for short periods of time. They will build a connection on how this process affects the body. The topic will then move onto the topic of alcoholic fermentation and how yeasts use this process to get energy when oxygen is not available. The students will learn how this alcoholic fermentation is used to make bread rise and to make alcoholic drinks.

Guided Practice:

The teacher will lead the students in a discussion concerning lactic acid fermentation while a runner experiences a shortage of oxygen. Students can make connection to real-world applications with athletes and proper nutrition. Also there will be a discussion on how yeast is used in the production of alcoholic drinks and bread making. A possible higher order connection can be made to the microbiology involved in fermentation.

Independent Practice:

The students will conduct an experiment in which they create an anaerobic environment for yeasts to make alcohol. Indicators will be used to show the presence of alcohol and carbon dioxide production.

Ending Review:

The final results of this lab will take a few days to actually visualize. We will discuss the results that we expect to see. The class will conduct a review of this unit with a MINDJOGGERS activity.
