Teach Engineering: Break the Tension
Students learn about and experiment with the concept of surface tension. How can a paper clip "float" on top of water? How can a paper boat be powered by soap in water? How do water striders "walk" on top of water? Why do engineers care...

Teach Engineering: Carve That Mountain
In this activity, students further investigate major landforms (e.g., mountains, rivers, plains, hills, oceans and plateaus). They build a three-dimensional model of a landscape depicting several of these landforms. Once they have built...

Teach Engineering: Static Cling
This hands-on activity explores the concept of static electricity. Students attract an O-shaped piece of cereal to a charged comb and watch the cereal jump away when it touches the comb. Students also observe Styrofoam pellets pulling...
TeachEngineering
Teach Engineering: Charge It!
Students use a balloon to perform several simple experiments to explore static electricity and charge polarization.
TeachEngineering
Teach Engineering: Build a Charge Detector
In this hands-on activity, students explore the electrical force that takes place between two objects. Each student builds an electroscope and uses the device to draw conclusions about objects' charge intensity. Students also determine...
TeachEngineering
Teach Engineering: Two Cell Battery
In this hands-on activity, students build their own two-cell battery. They also determine which electrolyte solution is best suited for making a battery.
TeachEngineering
Teach Engineering: Will It Conduct?
Students build their own simple conductivity tester and explore whether given solid materials and solutions are good conductors of electricity.
TeachEngineering
Teach Engineering: Switcheroo
In this hands-on activity, students construct a simple switch and determine what objects and what types of materials can be used to close a switch in a circuit and light a light bulb.
TeachEngineering
Teach Engineering: Light Your Way
When there is 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...

Teach Engineering: Bulbs & Batteries Side by Side
We are surrounded everyday by circuits that utilize "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are made of many simpler parallel and series circuits. In this hands-on activity, students build...
TeachEngineering
Teach Engineering: Stations of Light
Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a...
TeachEngineering
Teach Engineering: Potato Power
Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand...
TeachEngineering
Teach Engineering: Conductivity
Students make a simple conductivity tester using a battery and light bulb. They learn the difference between conductors and insulators of electrical energy as they test a variety of materials for their ability to conduct electricity.
TeachEngineering
Teach Engineering: The Grid
The class forms a "Presidential Task Force" for a week, empowered by the president to find answers and make recommendations concerning the future of the national power grid. Task force members conduct daily debriefings with their...
TeachEngineering
Teach Engineering: Make Your Own Temperature Scale
Students learn about the difference between temperature and thermal energy. They build a thermometer using simple materials and develop their own scale for measuring temperature. They compare their thermometer to a commercial...
TeachEngineering
Teach Engineering: Windmill of Your Mind: Distributed Energy Goes to School
Students research the feasibility of installing a wind-turbine distributed energy (DE) system for their school. They write a proposal (actually, the executive summary of a proposal) to the school principal based on their findings and...
TeachEngineering
Teach Engineering: Falling Water
Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment...
TeachEngineering
Teach Engineering: Waterwheel Work
Students learn the history of the waterwheel and common uses for water turbines today. They explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. They investigate the transformations of...

Teach Engineering: Capturing the Sun's Warmth
In the exploration of ways to use solar energy, students investigate the thermal energy storage capacities of different test materials to determine which to use in passive solar building design.
TeachEngineering
Teach Engineering: You're in Hot Water
To explore different ways of using solar energy, students build a model solar water heater and determine how much it can heat water in a given amount of time. Solar water heaters work by solar radiation and convection.
TeachEngineering
Teach Engineering: Cooking With the Sun
Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and...
TeachEngineering
Teach Engineering: Power to the People
Students read and evaluate descriptions of how people live "off the grid" using solar power and come to understand better the degree to which that lifestyle is or is not truly independent of technological, economic and cultural...
