Advanced chemistry scholars read about gas chromatography as a means of separating mixtures into their components. Then they try the technique on fingernail polish remover. Detailed instructions are provided via a lab sheet for your...

Students rank a list of everyday risks to compare with classmates. They rate each risk on both its ability to be controlled and its observability in the environment. Results are graphed.

Your biology class plays the role of epidemiologist when a mysterious illness breaks out in Kildare, USA. Using interviews with doctors, patients, and local citizens, maps, the results from different materials sampling, they work to...

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

High schoolers compare the perceived and actual risks of getting skin cancer, while looking at ways to minimize these risks. They may have very little grasp of the severity of the threat of skin cancer or be unaware of the increase in...

Students examine potential contamination on the environment due to products and by-products of a new industrial process. Students conduct a lab that explores the economic differences between choices of pollution cleanup and prevention.

Learners identify possible sources of health risks, types of exposures, routes of exposure, and populations that could be affected after discussing water pollution and environmental health hazards. After discussion, students conduct a...

Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to...

Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

Students isolate and determine the amount of plasticizer in polyvinyl chloride. They use Infrared Spectroscopy (IR) or Fourier Transform Infrared Spectroscopy (FTIR) and gravimetric techniques in this experiment.

Second graders complete a survey as class answering the question: "Did you eat breakfast this morning?". They place a tally mark in the column that best represents their answer. They then discuss the results in the graph.

Students identify basic weather instruments and how they are used to record weather data. Students define several vocabulary terms as stated in lesson. Students use basic instruments to record weather data in their area. Students use the...

Students, after reading a novel, utilize geographic skills to map out the places described in the novel. They collect data, envision spatial features and then design a map to work off of to complete their assignment. Each student also...

What kid isn't interested in Cell phones? They are technical and to operate them you must read an informational text. Older elementary students read an informational text, match vocabulary words with their meanings, and create sentences...

Seventh graders discover who the Tejanas were and how they contributed to World War II. In this World War II lesson, 7th graders listen to their instructor discuss who the Tejanas were prior to researching the contributions of three of...

Learners use the on-line affine recurrence plotter to graph equations. They work on-line to create graphs of trout in a trout pond and savings account balances when interest is compounded over time. Links to the four one-day lessons are...

Assign each group of 3-4 upper elementary engineers to a different type of transportation fuel. A background information page is provided to get them started with researching their assigned fuel. Each group then produces an exhibit...

Contrasting between the "Haves" and the "Have-Nots" of 18th-19th century Europe, this presentation explores the social and technological implications of the Industrial Revolution. Inventions, social trends, and scientific breakthroughs...

Learners use an Internet tool to explore shapes and how they combine.  In this patterns instructional activity, students create quilting patterns using various shapes.  Learners recognize how the shapes fit together.

When multiplying two-digit numbers by one-digit numbers, use a guided set of problems like this one. There are three examples for young mathematicians to reference, and they solve 20 equations. They are required to regroup for some....
