Title – We Have the Power!
By – Elisa Latreille
Primary Subject – Science
Secondary Subjects – Computers / Internet
Grade Level – 3
- This lesson plan is centered on the concept of renewable energy. It is a science unit that includes lessons on wind and solar power, as well as basic electric circuitry. The lessons will also cover some Earth Science concepts, as we will explore the earth’s supply of natural resources and discuss the importance of renewable energy both now and in the future. We will examine our power consumption and explore the idea of using renewable energy to fill our electricity needs. The unit will culminate with group investigations and presentations of renewable energy plans for our school. The duration of the unit is 4 weeks
(20 days, one hour per day)
- Why should our students learn about renewable energy and energy conservation?
- Because their future depends on it. Nicole Sands of Greenpeace summarizes the hazards associated with our nation’s current energy trends:
Our excessive reliance on fossil fuels feeds not only excessive air pollution, destruction of pristine areas and global warming, it also increasingly contributes to economic and regional instability around the globe. Continued fossil fuel use also contributes to the effects of global warming seen in rising temperatures, altered weather patterns and unseasonable droughts, floods and fires. (The Green Ribbon Pledge website) .
- Students will be able to identify renewable and non-renewable energy sources.
- Students will build and test basic electrical circuits.
- Students will be able to explain the importance of using renewable energy.
- Students will apply their knowledge of power consumption and resource availability to address a local issue.
- Students will work in small groups to improve collaboration and cooperation skills.

- Human Knot. (10 min.)
Have groups of 8-10 students stand in a circle. They must close their eyes, and reach across the circle and grab the hand of someone across from them. They will then take their other hand and grab the hand of someone else (who is not next to them). The group will then attempt to untangle the “knot” without letting go of one another’s hands. Teams can compete against one another to see which team can untangle their knot the fastest.
- Paperclip Challenge (15 min.)
Working in teams of 4-5 students, each team will be handed a paper bag containing the following items: a piece of paper, 10 paperclips, a piece of string, and five circular stickers. Teams will have five minutes to make the longest object, without talking at all.
Afterwards, have students use a tape measure to measure their object. Graph results on board. Look at the longest, and shortest, and some in between. Discuss what was easy and what was hard about creating their object. How did they communicate? What would they have done differently?
- Group Discussion (10 min.)
As a whole class, talk about the importance of listening to others, offering suggestions, and being respectful of others’ ideas. Talk about how teams are able to succeed at a task when everyone works together. Discuss how everyone has different strengths, and how these strengths can be used to benefit the group. Most importantly, talk about the importance of respecting one’s peers and working together to achieve a common goal.
- Recognizing Strengths in Others (25 min.)
The students will receive a class list, and will write one positive thing about each of their classmates. The teacher will then compile a list (on his or her own time) for each student with their classmates’ comments to be distributed on Day 2.

The students will work together in their groups and create plans to reduce the school’s electricity consumption +/or get power from renewable sources. They will be responsible for creating the plan as well as a presentation. Hand out copies of the assignment and the grading rubrics.
- Assignment: Create a “Renewable Energy Plan” for our school. Use information that you have learned over the past two weeks and do some research (using the websites from Day 9 or other appropriate resources) to develop your plan. It can include solar modules, wind turbines, energy conservation tips, and/or any other ideas that you may have. Make sure you explain how much energy each source would provide for the school. (For wind or solar power, please choose from the options listed in Appendix 2.) Will it be enough to power the whole school? How much would it cost? Create a 3-5 minute PowerPoint presentation to share your plan and your data with the class, your parents, and other teachers. It might be helpful to assign a role for each team member to ensure that everything gets done.
- Grading Rubric or “Look For’s”
- Team Participation
- You will fill out evaluations on yourself as well as your teammates. These will be incorporated into your grade. As the teacher, I will also be monitoring your participation level and teamwork in the project.
- Clarity of Ideas
- Have you used what you have learned over the past two weeks to help guide your plan?
- Could your plan be implemented? What are the necessary steps?
- How much would it cost?
- What problems might arise? (examples: solar panels might get covered with snow, or the wind might not blow for a week)
- How would you address these problems?
- Is your plan complete?
- Oral presentation
- Did you speak clearly so that everyone can hear and understand you?
- Were you making eye contact with the audience?
- Visual Aids
- Does your PowerPoint presentation provide valuable information?
- Does it clearly show your ideas?
- Have you checked to make sure that spelling is correct?
- Does your presentation have at least 5 slides?
- Computer and internet resources will be available so the students can do some additional research (with supervision) that will help them with their project.
- Try to have Paras or adult volunteers available to help answer questions, aid in research, and offer guidance during these five days.
- Encourage students to “dress professionally” for their presentation. It often helps them feel more confident. Give other presentation tips as you see fit (Examples: make eye contact, don’t fidget, speak clearly) to help students prepare.
- Oral presentation
- Team Participation
- Day 19: Groups should be wrapping up their presentations and rehearsing.
- Day 20: Group Presentations.
- Invite other classes, school personnel, and parents to see the presentations.
