This lesson will allow students to explore an important role of environmental engineers: cleaning the environment. Students will learn details about the Exxon Valdez oil spill, which was one of the most publicized and studied environmental tragedies in history. In the accompanying activity, they will try many “engineered” strategies to clean up their own manufactured oil spill and learn the difficulties of dealing with oil released into our waters.
Six Minutes of Terror
This lesson discusses how each component of a spacecraft is specifically designed so that a rover can land safely in six minutes. Also, students will learn how common, everyday materials and technology, like nylon, polyester and airbags, are used in space-age technology.
Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of
Pointing at Maximum Power for PV
Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power output. After collecting data, they calculate power for each resistance setting, creating a graph of current vs. voltage, and indentifying the maximum power point.
Cars: Engineering for Efficiency
Students learn how the aerodynamics and rolling resistance of a car affect its energy efficiency through designing and constructing model cars out of simple materials. As the little cars are raced down a tilted track (powered by gravity) and propelled off a ramp, students come to understand the need to maximize the energy efficiency of their cars. The most energy-efficient cars roll down the track the fastest and the most aerodynamic cars jump the farthest. Students also work with variables and
The Need for Shelter
In this lesson, the students will build a shelter in order to protect themselves from the rain. After the shelters are built, the class will perform durability and water proof testing on the shelters.
Particle Sensing: The Coulter Counter
Students are presented with a short lesson on the Coulter principle — an electronic method to detect microscopic particles and determine their concentration in fluid. Depending on the focus of study, students can investigate the industrial and medical applications of particle detection, the physics of fluid flow and electric current through the apparatus, or the chemistry of the electrolytes used in the apparatus.
It’s all In the Package
In this activity, students explore the concept of “reducing” solid waste and how it relates to product packaging and engineering advancements in packaging materials. Students read about and evaluate the highly publicized packaging decisions of two major U.S. corporations. They will evaluate different ways to package items in order to minimize the environmental impact, while considering issues such as cost, availability, product attractiveness, etc. Students will explore “hydrapulping” an
Backyard Weather Station
Students use their senses to describe what the weather is doing and predict what it might do next. After gaining a basic understanding of weather patterns, students act as state park engineers and design/build “backyard weather stations” to gather data to make actual weather forecasts.

Edd Presnell: Dulcimer Maker
Edd Presnell, a mountain craftsman and native of Watauga County, North Carolina, demonstrates and comments on the construction of a dulcimer. Presnell learned his craft from his father-in-law. Film includes a brief performance on a finished dulcimer by his wife, Nettie. This 16mm film is archived in the Thomas G. Burton and Jack Schrader collection in the Archives of Appalachia, East Tennesse State University.

Quick take on Pythagoras and his theorem
A topic once reserved for high school geometry, the Pythagorean theorem is now part and parcel of the middle school curriculum. These resources offer visual demonstrations that can make the abstract theorem more concrete for students and lead them in analyzing the mathematical relationships involved, as recommended by the Principles and Standards for School Mathematics. The last resource offers background information on Pythagoras himself.
Lines of best fit using least squares
Fit a line to the data in a scatter plot using your own judgment. Then compare the least squares line of best fit.
Library 2.0: A Journey of Metamorphosis
Libraries as we know them have changed over the years to become Learning Commons—less like rooms with books and more like learning spaces with a wide variety of resources.
Are You An Energy Efficient Consumer?
This activity engages students in learning about ways to become energy efficient consumers. Students examine how different countries and regions around the world use energy over time as reflected in night light levels. They then track their own energy use, identify ways to reduce their individual energy consumption, and explore how community choices impact the carbon footprint.
Indicators of Middle School Implementation: How Do Kentucky's Schools to Watch Measure Up?
Using responses of school personnel to a statewide survey, this study examined the perceived level of implementation of key tenets of the middle school concept as outlined by This We Believe: Successful Schools for Young Adolescents (National Middle School Association, 2003) in schools designated a Kentucky School to Watch as compared to nondesignated schools.,Volume 32, Number 6
Geologic Time: Eons, Eras, and Epochs
This resource guide from the Middle School Portal 2 project, written specifically for teachers, provides links to exemplary resources including background information, lessons, career information, and related national science education standards. This publication contains resources designed to do three things. The first is to complement teacher content knowledge and its relationship to the nature of geologic science. Geology is not a laboratory based science lending itself to traditional notions
Difference of Squares
This lesson uses a series of related arithmetic experiences to prompt students to generalize into more abstract ideas. In particular, students explore arithmetic statements leading to a result that is the factoring pattern for the difference of two squares. An excellent teaching idea on how to help students walk the bridge from arithmetic to algebra.
