Teach Engineering: Under Pressure
Students learn about Pascal's law, an important concept behind the engineering of dam and lock systems, such as the one that Thirsty County wants Splash Engineering to design for the Birdseye River (an ongoing hypothetical engineering...
TeachEngineering
Teach Engineering: Your River's Health
Students perform a macroinvertebrate survey to gauge the health of a local river. They collect water samples and count macroinvertebrates to learn how the health of a river's ecosystem can be determined by its river insect population.

Teach Engineering: Fish Friendly Engineering
Students further their understanding of the salmon life cycle and the human structures and actions that aid in the migration of fish around hydroelectric dams by playing an animated PowerPoint game involving a fish that must climb a fish...
TeachEngineering
Teach Engineering: Witnessing Evaporation
The engineers at Splash Engineering (the students) have been commissioned by Thirsty County to conduct a study of evaporation and transpiration in their region. During one week, students observe and measure (by weight) the ongoing...
TeachEngineering
Teach Engineering: Dam Pass or Fail
Students conduct Internet research to investigate the purpose and current functioning status of some of the largest dams throughout the world. They investigate the success or failure of eight dams and complete a worksheet. While...

Teach Engineering: Saltwater Circuit
Students build a saltwater circuit, which is an electrical circuit that uses saltwater as part of the circuit. Students investigate the conductivity of saltwater, and develop an understanding of how the amount of salt in a solution...
TeachEngineering
Teach Engineering: Water Desalination Plant
Students use a thermal process approach to design, build and test a small-scale desalination plant that is capable of significantly removing the salt content from a saltwater solution. Students use a saltwater circuit to test the...
TeachEngineering
Teach Engineering: Wild Wind
Students will learn the difference between global, prevailing and local winds. In this activity, students will make a wind vane out of paper, a straw and a soda bottle and use it to measure wind direction over time. Finally, they will...

Teach Engineering: Engineering for the 3 Little Pigs
The purpose of this activity is to demonstrate the importance of rocks, soils and minerals in engineering and how using the right material for the right job is important. The students build three different sand castles and test them for...

Teach Engineering: Snow vs. Water
Engineers work in many fields associated with precipitation. Engineers study glaciers to better understand their dates of formation and current demise. They deal with issues of pollution transport and water yield, and they monitor...
TeachEngineering
Teach Engineering: One World Ocean
In this activity, students learn about ocean currents and the difference between salt and fresh water. They use colored ice cubes to see how cold and warm water mix and how this mixing causes currents. Also, students learn how surface...
TeachEngineering
Teach Engineering: Can You Catch the Water?
Students construct a three-dimensional model of a water catchment basin using everyday objects to create hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to...
TeachEngineering
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...
TeachEngineering
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...
