Rationale

We choose this science topic because we think it is an efficient and rapidly growing

alternative energy source. From personal experiences we have continued to encounter more

and more organizations and buildings utilizing this alternative source of geothermal heat. One

of our group members has witnessed the cost effectiveness of a geothermal system in her

home, which intrigued us to research and learn more about this topic. In today’s society you

hear of continued depletion of natural resources so we feel alternative energy sources are key

to the continuation of the way we live.

Engineering relates to this topic because of the growing problem of limited energy

resources which needs to be solved for future generations. At some point a group of engineers

problem-solved and developed this system to take advantage of other natural resources found

in the Earth. Engineers have taken advantage of the Earth’s heat and turned it into a useful

technology to regulate the temperate of our homes and buildings.

This unit will benefit students because it introduces them to one of the world’s biggest

challenges of diminishing energy sources. The unit will educate the students of a process that

involves many science related topics that are linked to other subject areas including reading,

writing, mathematics, and engineering. The students will not only be informed of this new

process, but also challenged to analyze the advantages and disadvantages of geothermal

systems and traditional systems. In addition, students will learn to problem-solve and work

through a real world situation.

Logic Flow

Specific Concept: Geothermal Energy

Big Idea: Reflecting and analyzing alternative explanations and predictions can help form an opinion on current environmental issues.

Logic Flow: Energy cannot be created or destroyed, and can be transferred from one form to

another. Geothermal is a new and emerging alternative energy source. The geothermal system is a closed system transferring the Earth’s heat. Over time, geothermal energy is a cost effective heating and cooling system. Based on new knowledge, opinions are formed and used to persuade and inform

society.

Lesson 1: Basics of Energy

Overview: Students will use brainstorming activities like think-pair-share or in the form of a class brainstorm to come up with ideas on the topics of conservation of energy, forms of energy, and transfer of energy from one form to another. Students will be asked to brainstorm what is conservation of energy and the class will put the ideas together to form a definition. Students will then have a discussion on the different forms of energy and begin filling in their KWL chart with knowledge and what they want to learn focusing on the transfer of energy from one form to another.

Objective: - Students will discuss conservation of energy, forms of energy, and energy transfer

through the use of brainstorming activities.

Materials: - KWL Chart- Whiteboard- Computer- Projector

Anticipatory Set: The teacher will show a clip on energy by Bill Nye called, “Bill Nye The Science Guy on Energy” to review or introduce the basics of energy.

Procedural Steps:1. After the video the teacher will lead a class discussion on the basics of energy and

energy transfer referencing from the video.-What is Bill Nye trying to say in this video? How did you know that?-What new things did you learn about energy and energy transfer from Bill?-How does Bill Nye’s demonstration of energy transfer relate to what we already knew about it?

2. The teacher will then ask students to do a think-pair-share discussion about what conservation of energy means.

3. As a class, come up with a definition for conservation of energy. Make a list of all of the student’s ideas and then come up with an overall definition and write it on the board and add it to the KWL chart.

4. Have a class discussion on the different forms of energy. -Specifically kinetic, potential, and thermal (heat)

5. Fill out the K in the KWL chart with the information discussed in the lesson.

Lesson 3: A Geothermal System

Overview: The teacher will begin by generating discussion based on what was learned the previous day as a foundation for the day’s lesson. Then, the teacher will explain how a geothermal system works as a closed circuit transferring the Earth’s heat. As a class we will define a closed system. The teacher will divide the students into groups (4 groups of 5, for example- depending on availability of supplies) and hand out an instruction sheet to each group (see instruction sheet for supplies). Teacher will go over instructions with the class. Students will then cooperatively build the circuit and be able to feel the heat transfer that is similar to that of a geothermal energy system. After building the system, students will have to reflect on the project and answer questions about it (questions are with instructions). Students will continue to add their KWL charts.

Objectives: - Students will work cooperatively in groups to build and engineer a simulation of a

geothermal energy system with given supplies and instructions.- Students will use knowledge they gained from the simulation to answer the reflection

questions provided and explain how the simulation is like that of a geothermal system.

Materials: - KWL chart- Instruction Sheet- Fish pump- PCV clear plastic pipe- Ice bath of water and ice- Food coloring- Hair dryers

Anticipatory Set: Review what was learned yesterday. Ask questions like, “Tell me something new you learned yesterday when we were doing our crossword puzzle.” Have several people answer this question to see what the students learned. Ask questions based on what kinds of answers you get from the students. Make sure to brush on the parts of a geothermal energy system if no one brings it up, as this is what is going to be taught today. Add to the KWL chart as new information is shared.

Procedural Steps:1. Introduce activity. Tell what it is and show the parts that go into it. You do not need

to go through the steps, as they are on the instruction sheet and they can get practice with following directions.

11

2. Divide the class into groups.3. Pass out instruction sheet (attached in resources) and go over the questions at the

bottom. Direct students to answer these questions after they have put together their circuit.

4. Let students gather materials and get started on constructing the circuit. Help as needed.

5. When students are finished, they will need to fill out their worksheet as a group. 6. Have students turn them in to be graded.

Closure: Once all students have turned their papers in, go through the questions and discuss as a class. Talk about how the different parts of the tube felt warm or cold, and how this relates to a geothermal energy system. The hairdryers and ice bath are similar to the temperatures under the earth. The water carries the temperature from those and brings it elsewhere, often into households, schools, businesses, or other buildings to provide heating and cooling.

Assessment: Students will be assessed on the completion of their construction of the circuit in their groups. The group must correctly assemble the circuit to demonstrate understanding. This will be recorded on the overall unit checklist. The students will also be assessed on the accuracy and clarity of their reflection questions. Two points will be awarded for each question. One for completion, one for clarity and accuracy.

12

Lesson 4: Benefits of Geothermal

Overview: The teacher will lead a discussion about the placement of geothermal energy because it is a new and emerging heating and cooling system in homes because it is renewable resource and is cost effective. Students will then complete a cost effectiveness worksheet to visually see the cost comparison between a traditional system and the geothermal system. Students will work in groups and share strategies with the class and discuss the results. Students will complete their KWL charts for the unit.

Students will be introduced to their final unit project. They will be instructed to create a public service announcement (commercial-like) that could be used to persuade others to pursue alternative forms of energy, specifically a geothermal system. Student will need to include a basic overview of the energy type and beneficial reasons for choosing geothermal energy. Students will be placed in groups of three and asked to write a detailed script of what they will say and do for their public service announcement.

Objective: - Students will analyze a real-life geothermal system’s cost and figure the efficiency

through problem solving.

Materials: - KWL chart- Cost Effectiveness Worksheet- Projector- Computer

Anticipatory Set: Review what happened in class the day before with doing the circuits. Discuss the similarities between the circuit and a geothermal energy system. Add the things that were learned to the KWL chart. When done adding things, introduce the topic of the benefits of geothermal. Ask the class what some benefits might be and see what they come up with. Have a discussion based on what the class answers. Talk about cost effectiveness and share how a geothermal system is expensive to install, but costs less monthly. Ask the class which would then turn out to be a better deal?

Procedural Steps:1. Have the class pair up.2. Hand out the cost effectiveness worksheets and have the students work on it. Help as

needed.

13

3. When everyone is done, go over the answers to the problems. Have students share their solutions and how they got their answers on the board or on the projector.

4. Have the class turn their worksheets in. 5. Refer back to the KWL chart and finish it for the unit. Add what the students learned

from the cost effectiveness activity. 6. Introduce the PSA assignment, where the students will make a public service

announcement about geothermal energy. Show an example of a student made PSA found at http://www.youtube.com/watch?v=vcj1JivmlQs.

7. Hand out the rubric and instruction sheet (found in resources) for the assignment and divide the class into groups of 3-4. Explain to them what they are to do, which is write a script, use the flip cameras to record, and upload to iMovie and make their PSA.

8. If using the technology is new for the students, go over the rules for using the technology and also spend some time showing them how it works.

Closure: Give them work time to start putting together their scripts. Have them turn in their scripts when they are finished so that the teacher can look over them to be sure they understand the assignment and that everything is appropriate. Help as needed.

Assessment: Students will be assessed on the completion of the cost effective worksheet and strategies they used to solve the problems. The teacher will start an informal evaluation based on participation towards the group project. This will be recorded on the overall unit checklist found in the resource section as the student will receive a tally for participation for that day.

Lesson 5: Promote Geothermal

Overview: Students will continue to work on their scripts for their public service announcements. Time will be given for students to practice and record their scripts using flip cameras. Scripts should be reviewed by teacher before final recording. Students can then upload and edit their movies using IMovie to make a final product to be shared with family, community members, and administration.

Objectives: - Students will write a script containing an overview of geothermal as an energy transfer

system and the benefits of incorporating the alternative energy system.- Students will produce a public service announcement of their written script using Flip

cameras and imovie.

Materials: - KWL Chart- Flip Cameras- Computers

Anticipatory Set: The teacher will begin by reviewing the information on the KWL chart and then give directions to continue to work with your groups to complete your public service announcement with the necessary steps.

Procedural Steps:1. The teacher will provide a brief explanation of how to use Flip cameras to record and

upload to a computer, and then how to edit using iMovie by demonstrating an example. -Directions: Power button turns it on. Main button starts and stops recording. Zoom arrows zoom in and out.

2. Students will finalize their scripts and have them reviewed by the teacher.3. Students should practice their scripts and make any adjustments necessary based on

teacher feedback. 4. Students will record their scripts and upload their product to iMovie and edit adding

pictures and music to create their final product. -Directions: Plug Flip camera in to USB port. Open iMovie and drag imported video clips into the program. Put the clips in order and start editing using effects and tools.

5. The teacher should assist students in uploading and editing.6. The videos will then be uploaded to YouTube with teacher instructions so they can

easily be shared with family, administration, and community members.

15

-Directions: Teacher should create a YouTube channel for the class. Have students go to YouTube and sign in under class name. Click upload and choose the video file.

Closure: The teacher will share the videos with the class to sum up the unit on geothermal energy and encourage students to share this new information with others.

Assessment: Students will be informally assessed on their participation and ability to work in groups with a tally on the overall unit checklist. Formally students will be assessed on the scientific ideas and completeness of their script and their overall production and quality of persuasion.

16

Unit Learning Assessment PlanThe students will be assessed on the unit objectives through a final project of creating a

public service announcement summarizing all of the information they have learned throughout the unit about geothermal energy. The students will use the information they researched using technology throughout the unit to provide factual information in their presentation to make it a reliable source. The information in the presentation will show their understanding of geothermal as a type of energy and energy transfer system by starting their public service announcement with an overview of what geothermal energy is. The students will then use the information they have learned to add a persuasive ending to their public service announcement. This will be done using a Flip camera and iMovie in order to incorporate technology and be able to share their public service announcement with administration, parents, and the community. Overall, this project will be done in groups which will require students to work collaboratively to create a quality final product.

Follow the instructions. 1. Gather supplies.

Fish pump clear plastic tubing tub for ice water

cup of water food coloring 2 hair dyers

2. Add one or two drops of food coloring to the cup of water and mix it around so that the coloring is even.

3. Hook fish pump up to clear plastic tubing on one end. 4. Take the open end of the tube and place it into the cup of colored water. Turn your

pump on and let it begin to suck in some of the water. Place your fish pump in your tub for the ice water temporarily.

5. When the other end of the fish pump begins to spew water, take the end of the tube that is in the cup of water and put it on the end of the pump that is omitting water.

6. This will create your circuit. You may leave your fish pump on to ensure that it works properly before you set up the rest of your experiment.

7. When ready, fill your tub for ice water up with ice and water. Place part of your tubing in the water so that part of it goes in and the other part goes out. Do this close to the fish pump so that you still have more length of tubing to work with.

8. Then, with the rest of your tubing, set up two hairdryers close to the tube. Plug them so that they can be running. Make sure they are at the warmest setting.

9. For the last step, turn on your hair dryers and the fish pump. Answer the following questions.

Answer the following questions. One point for completion, one point for accuracy and clarity.1. Locate the spot of tubing that is just coming out of the ice bath, but is not directly in the
