Uncountable times every day with the merest flick of a finger each one of us calls on electricity to do our bidding. What would your life be like without electricity? Students begin learning about electricity with an introduction to the most basic unit in ordinary matter, the atom. Once the components of an atom are addressed and understood, students move into the world of electricity. First, they explore static electricity, followed by basic current electricity concepts such as voltage, resistance and open/closed circuits. Next, they learn about that wonderful can full of chemicals the battery. Students may get a "charge" as they discover the difference between a conductor and an insulator. The unit concludes with lessons investigating simple circuits arranged "in series" and "in parallel," including the benefits and unique features associated with each. Through numerous hands-on activities, students move cereal and foam using charged combs, use balloons to explore electricity and charge polarization, build and use electroscopes to evaluate objects' charge intensities, construct simple switches using various materials in circuits that light bulbs, build and use simple conductivity testers to evaluate materials and solutions, build and experiment with simple series and parallel circuits, design and build their own series circuit flashlight, and draw circuits using symbols.

Students learn how water is used to generate electricity. They investigate water's potential-to-kinetic energy transformation in hands-on activities about falling water and waterwheels. During the activities, they take measurements, calculate averages and graph results. Students also learn the history of the waterwheel and how engineers use water turbines in hydroelectric power plants today. They discover the advantages and disadvantages of hydroelectric power. In a literacy activity, students learn and write about an innovative new hydro-electrical power generation technology.

Students solidify their understanding of the terms "circumference" and "rotation" through the use of LEGO MINDSTORMS(TM) NXT robotics components. They measure the circumference of robot wheels to determine how far the robot can travel during one rotation of an NXT motor. They sharpen their metric system measurement skills by precisely recording the length of a wheel's circumference in centimeters, as well as fractions of centimeters. Through this activity, students practice brainstorming ways to solve a problem when presented with a given scenario, improve their ability to measure and record lengths to different degrees of precision, and become familiar with common geometric terms (such as perimeter and rotation).

Students develop an understanding of the concepts of "push" and "pull" as they "save" stuffed animals from danger using LEGO MINDSTORMS(TM) NXT robots. After learning more about the concepts through a robot demonstration, students explore the concepts themselves in the context of saving stuffed animala from the table edges. They choose to either push or pull the animal to safety, depending on the orientation of the robot and toy. They see the consequences of their choices, learning the importance of understanding these force concepts and the differences between them.

With the challenge to program computers to mimic the human reaction after touching a hot object, students program LEGO® robots to "react" and move back quickly once their touch sensors bump into something. By relating human senses to electronic sensors used in robots, students see the similarities between the human brain and its engineering counterpart, the computer, and come to better understand the functioning of sensors in both applications. They apply an understanding of the human "stimulus-sensor-coordinator-effector-response" framework to logically understand human and robot actions.

In this lesson, students begin to focus on the torque associated with a current carrying loop in a magnetic field. Students are prompted with example problems and use diagrams to visualize the vector product. In addition, students learn to calculate the energy of this loop in the magnetic field. Several example problems are included and completed as a class. A homework assignment is also attached as a means of student assessment.

Students strengthen their communicate skills about measurements by learning the meaning of base units and derived units, including speed one of the most common derived units (distance/time). Working in groups, students measure the time for LEGO MINDSTORMS(TM) NXT robots to move a certain distance. The robots are started and stopped via touch sensors and programmed to display the distance traveled. Using their collected data, students complete a worksheet to calculate the robots' (mean/average) speeds at given motor powers.

Student pairs first act out the instructions a robot is given with one person providing instructions and the other person following the instructions. This activity helps students understand how robots are programmed and with what type of precision commands must be given. Then students program LEGO MINDSTORMS(TM) NXT taskbots to navigate a simple maze. The goal is to teach students that robot computers simply follow directions exactly as they are given, thus one must be very clear and logical with programming instructions.
