## Measuring Voltage Using a Microcontroller (Lesson 1)

Students will apply Ohm’s Law. Students will use a multimeter to measure current, voltage, and resistance. Students will use a breadboard to set up a series circuit. Students will read circuit diagrams. Students will calculate times for an RC circuit to change state. Students will prove that resistors in series have an equivalent resistance equal to their individual sums. Students will program the Basic Stamp to measure voltage levels in a voltage divider and RC circuit.

In this lesson students will be introduced to series circuits, resistors, a photoresistor and a microcontroller. There’s a lot here, but it boils down to making a voltage divider circuit and measuring the voltage at different points. A second circuit includes an RC component. Teachers can edit this down to just a photoresistor if time and/or... View full description >>

14. Students will identify the causes and solutions to various complications that arise in the construction of circuits.

15. Students will use the design process to create a roof to hold an adequate number of solar modules to power an LED and a fan.

16. Students will understand how to make a geometric net (a 2D drawing that when folded creates a 3D shape) for designing a roof.

In Lesson 1, the lesson focuses on understanding how the angle and orientation affect the amount of energy that is generated through use of a solar cell. Paper azimuth finders, Keva Planks, and multimeters will be used in order for students to draw conclusions about the optimal placement of a solar cell. This lesson will prepare students for...

## Non-renewable Energy/Global Warming/Pollution (Lesson 3)

Students will explore why there is a need for energy efficiency and renewable energy. Students will determine how non-renewable and renewable energy are a part of our lives. Students will understand how the greenhouse effect and nonrenewable energy sources relate to climate change.

This lesson will introduce the students to worldwide problems that we have with energy. (91% of the energy we use is non-renewable, 9% of the energy we use is renewable). Students will explore the greenhouse effect as part of this lesson and relate this process to climate change. View full description >>

## Observing and Keeping Records (Lesson 7)

Students will review scientific observations methods learned earlier and the application of those methods for the solar energy unit. Students will practice observations and data recording. Students will explain the importance of selecting useful variables from which they can collect data. Students will be prepared to implement an experiment in the classroom that they can draw conclusions from.

Students will review basic scientific observation methods and the importance of keeping and reporting accurate observations. Teacher will discuss with students the different types of variables that they can

## Our Place in Space: Cosmic Rays

Students will learn how the sun affects their school by measuring the temperature at different locations around the building in the fall, winter, and spring. They will learn how to measure solar energy and look for trends in temperature and solar power over the year. These trends will then be used to investigate how energy reaches Earth from the Sun.

Using a map of school buildings, students will pick four areas to monitor over the year using wireless weather stations and the Solar Power Meter. In a following lesson, students will use an online

## Our Place in Space: Cosmic Ray Detector

• Students will discuss how energy from the sun is transmitted in a variety of forms that perform different amounts of work. • Students will identify multiple pieces of evidence that demonstrate energy being transmitted from the sun.

The students will be introduced to solar radiation with an activity centered on using a

## Our Place in Space: Tracking the Earth's Path Around the Sun

Students will be able describe how the Earth orbits the Sun and how the tilt of the planet creates the seasons by recording the ‘Sun’s path’ in our sky in the fall, winter, and spring.

During sessions in October, January, and April we will discuss observations about the weather during that season (temperature, length of day, precipitation) and explore how this relates to the Earth’s

## Our Sensational Sun (Lesson 3)

At the end of this lesson, students will have written numerous facts about the sun that they 1) already know, 2) want to know and 3) have learned.

The purpose of this lesson is to record information that the students learn about the sun on a chart. This chart will be used for the entire unit. It will serve as a good reference for guiding the lessons and providing information for student research. View full description >>
