Warm-Up: Sun's Power (5 minutes)

"Good morning/afternoon everyone! Let's start with a quick warm-up. Take a moment to think about the sun. Besides giving us light and warmth, how do you think we use the sun's energy in our daily lives? Or, where have you seen solar energy being used? Turn and talk to a partner for about a minute to share your ideas."

(Allow students to discuss. Bring the class back together.)

"Fantastic ideas! We see solar energy in everything from calculators to streetlights, and even in some homes. Today, we're going to dive into how we can actually use the sun to power things, specifically thinking about our own classroom!"

Introduction to Solar Power (10 minutes)

(Transition to Solar Power Mini-Station Slides - Slide 1: Sunshine to Circuits)

"Look at this image. Imagine our classroom running on sunshine. What does that idea spark in your mind? What would it look like, how would it work, and why might it be a really good idea?"

(Allow for a few student responses.)

"Great. Now, let's get into the science of it."

(Transition to Solar Power Mini-Station Slides - Slide 2: What is Solar Power?)

"At its core, solar power is simply harnessing energy from the sun. The key devices for this are solar panels, also known as photovoltaic cells. Has anyone heard that term 'photovoltaic' before? What do you think 'photo' and 'voltaic' might refer to?"

(Guide students to connect 'photo' with light and 'voltaic' with electricity.)

"Exactly! 'Photo' means light, and 'voltaic' refers to voltage or electricity. So, photovoltaic cells convert light directly into electricity. When sunlight hits the panel, it excites electrons within the material, causing them to move and create an electric current. It's like tiny solar-powered pinball machines happening millions of times over!"

"Now, a solar panel alone isn't enough to power our classroom. We need a few other important pieces. Think of it like a team working together. The solar panels are the star players, but they need support.

First, the solar panels convert sunlight into direct current, or DC electricity. Most of our devices, however, use alternating current, or AC electricity. So, we need an inverter to change that DC power into AC power. It's like a translator for electricity.

Sometimes, the sun isn't shining, or we produce more electricity than we immediately need. That's where a battery comes in. It's optional, but super useful for storing excess energy. If we have a battery, we also need a charge controller to make sure the battery doesn't overcharge, which can damage it. And, of course, we need safe wiring and mounting to put everything together.

Any questions about these components? Which one do you think is the most crucial, and why?"

(Address student questions and facilitate a brief discussion on component importance.)

(Transition to Solar Power Mini-Station Slides - Slide 4: Your Classroom Mini-Station)

"So, if we had a mini-solar power station right here, what could it power in our classroom? Think about what we use daily. What are the benefits of using solar power for these things?"

(Encourage students to list items and discuss the benefits like clean energy, cost savings, and learning opportunities.)

Classroom Solar Challenge Discussion (10 minutes)

(Transition to Solar Power Mini-Station Slides - Slide 5: The Classroom Solar Challenge)

"Alright, now for the challenge! I want you to imagine you are a team of engineers tasked with designing a classroom-sized solar power station. In small groups, discuss the following questions:

• What are our classroom's main energy needs? (e.g., lights, projectors, charging devices)
• Where would be the best place to put the solar panels to get the most sun?
• What challenges might you face in setting this up? (e.g., cost, space, weather)
• How would you overcome these challenges or make your mini-station as efficient as possible?

You'll have about 7 minutes for your discussion, and then we'll share some of your brilliant ideas with the whole class."

(Divide students into groups. Circulate to provide guidance and answer questions. After 7 minutes, bring the class back.)

"Let's hear some of your amazing ideas! What were some of the key energy needs you identified? Where would your panels go? And what was a big challenge you discussed, and how would you tackle it?"

(Facilitate a brief share-out, ensuring a few groups contribute.)

Cool-Down: Solar Reflection (5 minutes)

(Transition to Solar Power Mini-Station Slides - Slide 6: Powering Our Future)

"Excellent work everyone. As we wrap up, remember that solar energy is a powerful tool for creating a more sustainable future. Even small steps, like imagining and discussing a classroom mini-station, can make a big difference in how we think about energy.

For our cool-down, please take out a piece of paper or open a document on your device. I want you to write down one key takeaway you learned today about solar power and its potential impact, either in our classroom or in the world."

(Collect responses or allow students to keep them for personal reflection.)

"Thank you, class! You've been brilliant engineers and thinkers today. See you next time!"
