This activity is an activity where students build a motor, learn motor operation and theory, interpret their understanding through troubleshooting, and develop a new, experimental question related to the motor. One follow-up activity would be coupling their motor to a fan blade or other axle to convert electrical energy to magnetic energy into mechanical motion for real world application.

To better understand electricity, students investigate the properties of materials based on their ability to dispel static electricity. They complete a lab worksheet, collect experimental data, and draw conclusions based on their observations and understanding of electricity. The activity provides hands-on learning experience to safely explore the concept of static electricity, learning what static electricity is and which materials best hold static charge. Students learn to identify materials that hold static charge as insulators and materials that dispel charge as conductors. The class applies the results from their material tests to real-world engineering by identifying the best of the given materials for moving current in a solar panel.

Students learn how the sun can be used for energy. They learn about passive solar heating, lighting and cooking, and active solar engineering technologies (such as photovoltaic arrays and concentrating mirrors) that generate electricity. Students investigate the thermal energy storage capacities of test materials. They learn about radiation and convection as they build a model solar water heater and determine how much it can heat water in a given amount of time. In another activity, students build and compare the performance of four solar cooker designs. In an associated literacy activity, students investigate how people live "off the grid" using solar power.

During a power failure, or when we go outside at night, we grab a flashlight so we can find our way. What happens inside a flashlight that makes the bulb light up? Why do we need a switch to turn on a flashlight? Have you ever noticed that for the flashlight to work you must orient the batteries a certain way as you insert them into the casing? Many people do not know that a flashlight is a simple series circuit. In this hands-on activity, students build this everyday household item and design their own operating series circuit flashlights.

Students are introduced to circuits through a teacher demonstration using a set of Christmas lights. Then students groups build simple circuits using batteries, wires and light bulbs. They examine how electricity is conducted through a light bulb using a battery as a power source. Students also observe the differences between series and parallel circuits by building each type.

Students learn how to set up pre-programmed microcontroller units like the Arduino LilyPad and use them to enhance a product’s functionality and personality. They do this by making plush toys in monster shapes (template provided) with microcontrollers and LEDs sewn into the felt fabric with conductive thread to make circuits. At activity end, each student will have created his or her own plush toy, complete with LEDs that illuminate in a specified sequence: random twinkle, blink, heartbeat and/or breathing.

Students are given an engineering challenge: A nearby hospital has just installed a new magnetic resonance imaging facility that has the capacity to make 3D images of the brain and other body parts by exposing patients to a strong magnetic field. The hospital wishes for its entire staff to have a clear understanding of the risks involved in working near a strong magnetic field and a basic understanding of why those risks occur. Your task is to develop a presentation or pamphlet explaining the risks, the physics behind those risks, and the safety precautions to be taken by all staff members. This 10-lesson/4-activity unit was designed to provide hands-on activities to teach end-of-year electricity and magnetism topics to a first-year accelerated or AP physics class. Students learn about and then apply the following science concepts to solve the challenge: magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's law and Faraday's law. This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn.

Students learn about engineering applications in artistic venues by designing and creating eye masks that each contain three LEDs. They explore parallel circuits with their LEDs, and sew with conductive thread to create light-up displays on their masks, gaining hands-on experience in using engineering technologies as well as custom product design and assembly.
