Teach Engineering: Things That Matter to Flocculants
Prior to reaching households, water is exposed to a variety of treatments designed to render it fit for human consumption and use. One of the first treatment steps is the removal of suspended solids using chemical additives called...

Teach Engineering: At the Doctor's
In this simulation of a doctor's office, students play the roles of physician, nurse, patients, and time-keeper, with the objective to improve the patient waiting time. They collect and graph data as part of their analysis. This serves...

Teach Engineering: Whose Field Line Is It, Anyway?
Students teams each use a bar magnet, sheet of paper and iron shavings to reveal the field lines as they travel around a magnet. They repeat the activity with an electromagnet made by wrapping thin wire around a nail and connecting...
TeachEngineering
Teach Engineering: The Good, the Bad and the Electromagnet
Using plastic straws, wire, batteries and iron nails, student teams build and test two versions of electromagnets-one with and one without an iron nail at its core. They test each magnet's ability pick up loose staples, which reveals the...

Teach Engineering: Microbes Know How to Work!
Students design systems that use microbes to break down a water pollutant (in this case, sugar). They explore how temperature affects the rate of pollutant decomposition.
TeachEngineering
Teach Engineering: Grow Your Own Algae!
Students discover how tiny microscopic plants can remove nutrients from polluted water. They also learn how to engineer a system to remove pollutants faster and faster by changing the environment for the algae.
TeachEngineering
Teach Engineering: Natural and Urban "Stormwater" Water Cycle Models
Students apply their understanding of the natural water cycle and the urban stormwater water cycle, as well as the processes involved in both cycles to hypothesize how the flow of water is affected by altering precipitation.

Teach Engineering: Just Breathe Green: Measuring Transpiration Rates
Through multi-trial experiments, students are able to see and measure something that is otherwise invisible to them- seeing plants transpire. This information will allow students to consider how a plant's unique characteristics (leaf...
TeachEngineering
Teach Engineering: Does Media Matter? Infiltration Rates and Storage Capacities
Students gain a basic understanding of the properties of media- soil, sand, compost, gravel- and how these materials affect the movement of water (infiltration/percolation) into and below the surface of the ground.
TeachEngineering
Teach Engineering: Making "Magic" Sidewalks of Pervious Pavement
Students use everyday building materials- sand, pea gravel, cement and water- to create and test pervious pavement. Groups are challenged to create their own pervious pavement mixes, experimenting with material ratios to evaluate how...

Teach Engineering: A Guide to Rain Garden Construction
Student groups create personal rain gardens planted with native species to provide a green infrastructure and low-impact development technology solution for areas with poor drainage that often flood during storm events.
TeachEngineering
Teach Engineering: Tension Racers!
Students see how different levels of surface tension affect water's ability to move. Teams "race" water droplets down tracks made of different materials, making measurements, collecting data, making calculations, graphing results and...
TeachEngineering
Teach Engineering: Get Your Charge Away From Me!
This activity is an easy way to demonstrate the fundamental properties of polar and non-polar molecules (such as water and oil), how they interact, and the affect surfactants (such as soap) have on their interactions. Students see the...
TeachEngineering
Teach Engineering: Down With the Clip!
Students see how surface tension can enable light objects (paper clips, peppercorns) to float on an island of oil in water, and subsequently sink when the surface tension of the oil/water interface is reduced by the addition of a...

Teach Engineering: Let's Get Dirty
In a very hands-on activity, students observe and feel the differences between two cleaning methods, with and without hand soap, using coffee grounds to represent "dirt."Most of the dirt and bacteria on our hands is encased in a thin...
TeachEngineering
Teach Engineering: Grading Congestion
Students construct a model roadway with congestion and apply their knowledge of level of service (LOS) to assign a grade to the road conditions. The roadway is simply a track outlined with cones or ropes with a few students walking...
TeachEngineering
Teach Engineering: How Dense Are You Lab
Students determine the mass and volume of soil samples and calculate the density of the soils. They use this information to determine the suitability of the soil to support a building foundation.
TeachEngineering
Teach Engineering: Designing a Medical Device
Students learn the engineering design process by following the steps, from problem identification to designing a device and evaluating its efficacy and areas for improvement. A quick story at the beginning of the activity sets up the...
TeachEngineering
Teach Engineering: Electrocardiograph Building
This activity will build upon the concepts taught in the lesson The Strongest Pump of All. The activity will pull together the concepts of bioelectricity, electrical circuits, and biology. It will allow the students the opportunity to...

Teach Engineering: Constructing Sonoran Desert Food Chains and Food Webs
Is the food chain shown above accurate? Does the first link depict a producer, the second link a herbivore, and the third link an omnivore / carnivore? Students must correctly determine whether a species is a producer or consumer, and...

Teach Engineering: Computer Simulation of the Sonoran Desert Community
The computer program's simulation of a Sonoran desert community should ultimately strengthen the student's comprehension of what is required for a natural ecosystem to sustain itself (remain in balance). This computer simulation program...
