1. Watch the video and answer the questions in Edpuzzle.
2. Real-World Ratio and Rate reasoning: How to power the skate park. a. Describe the way solar energy works in the video. How does the solar cell create- electricity and how does the battery help this process?
b. How many lights need solar power in the skate park?
c. How many solar panels are needed and how many batteries are needed to charge the lights?
d. Why does the CyberSquad need to find the area of the solar panels?
e. What is the length of each panel? What’s the width? What is the area and how did they figure it all out?
f. Once the CyberSquad has the area of an individual solar panel, how do they find the area they need for all the combined panels?
g. How do they find out if the area of the roof is the right side for the solar panels? Describe in your own words.
h. Why does Jackie say that the team needs to come up with a new idea for the solar panels?
i. What does she recommend they do and why?
j. What’s the area of the new solar panels? How they figure that out? What’s the math?
k. How many batteries did they need for that? Describe how they figured out the math.
l. How was area involved in this work?
If we were to put together a table to help show the relationship between some of these important pieces it might look like this.
You now have an opportunity to start designing your solar dream house. You will start with the roof, because that’s where the solar panels will be located to generate your solar power.
Each square centimeter of your graph paper will represent one square foot in real life. This is the scale we will use.
Design an interesting shape for the front side of your roof. Imagine it is flat on your "paper." Calculate the area of this side of your roof.
What will your roof look like? Use the Visualize It! to draw your roof. (Take a screenshot of the "Visualize it")
Now using the information from the Solar Power Table from a few pages back (you will need to click back to locate the information), figure out how many solar panels you can fit on your roof. Then figure out how long your roof can keep the lights on in the Cyber Skate Park with that same number of 50 lights and 1 hour of charging time.
Do this same calculation for ½ hour of charging time and then for only 15 minutes of charging time. Share your work with the larger class and compare answers and strategies.
