## Becoming Green Energy Experts

Icon:

This Michigan State University/Lansing Boys and Girls Club partnership demonstrates the powerful result of giving youth the science background and tools they need to carry out investigations of their own design, and to communicate their knowledge in their own voice.

## Electricity | Science Trek

Icon:

In this video segment from IdahoPTV's Science Trek you follow electricity from its generation at a hydroelectric plant to your home, while learning some of the vocabulary about electricity. Discover some other sources of electricity, and why it is so dangerous.

Lessons in Matter and Energy, from WOSU Public Media, is a series of eight learning modules that demonstrate physical science concepts and phenomena. The series captures some of the most engaging demonstrations presented at the Center of Science and Industry (COSI) in Columbus. The demonstrations clarify essential properties of matter and the nature and transfer of energy. Accompanying each module is a Teacher’s Guide, on video, and a set of assessment tools which include suggested tasks to test comprehension, a scoring rubric and a student booklet. Lessons in Matter and Energy is intended to complement curricular resources in grades 4 to 8.

## Unit 4, Segment E: Kinetic Energy and Gravitational Potential Energy | Physics in Motion

Icon:

Gravitational potential energy and kinetic energy are defined and explained mathematically through multiple example problems.

## Unit 4, Segment H: Conservation of Energy | Physics in Motion

Icon:

We explore the inner workings of a hydroelectric dam as we learn about the law of conservation of energy. The difference between conservative and non-conservative forces is illustrated and we work through an example problem involving gravitational potential energy and kinetic energy.

## Unit 5, Segment E: Current Electricity | Physics in Motion

Icon:

Current electricity is defined as we explore the relationship between voltage, current, and resistance. Ohm's law is introduced as well as the equation relating electric force and electric field.

## Unit 5, Segment B: Static Electricity | Physics in Motion

Icon:

We explore static electricity as we learn about charging by friction, conduction, and induction.

## Unit 4, Segment D: Work | Physics in Motion

Icon:

Work and energy are explored in this segment as we look at the work done by various types of forces. We also investigate what it means for the work done by an object when displacement and force are oriented in a variety of different ways.

## Unit 5, Segment G: Series Circuits | Physics in Motion

Icon:

We learn about the properties of series circuits. We examine how to find the total voltage, current, and resistance of a series circuit and learn how to find these things across individual resistors within the circuit.

## Unit 5, Segment D: Electric Potential Energy and Electric Potential | Physics in Motion

Icon:

We differentiate between the concepts of electric potential energy and electric potential by exploring electric potential energy qualitatively, looking at a charge between two parallel plates, and solving for electric potential in an example problem.
