Linear equations are all about form. The fifth part in a unit of nine works with the different equivalent forms of linear equations. Class members become familiar with each form by identifying key aspects, graphing, and converting...

It is not always easy to walk the straight and narrow. In the sixth portion of a nine-part unit, groups actively recreate a graph depicting motion. Individuals walk toward or away from a motion detector while trying to match a given...

The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value...

How can nanoparticles be used in the battle against skin cancer. Class members take on the question as they gather information about electromagnetic radiation, specifically ultraviolet radiation. Pupils learn about the mathematical...

Though UV radiation can damage skin, it isn't all bad. The third installment in a six-part series allows the class to study the structure and function of skin. They learn about the different types of skin cancer and the SPF rating...

Please, sir, can I have a few thousand dollars for my research? The last installment in a six-part instructional activity has the pupils develop a grant proposal. Class members apply their knowledge of skin cancer, ultraviolet radiation,...

It is best to know all about the skeletons in the closet. The third segment in a five-part series focuses on bone structure, development and growth, and functions. Class members connect what they learn to their study of...

So is that what you meant by rubber legs? The activity has pairs subject a chicken bone to vinegar and observe what happens over a period of days. Individuals then write up a lab report and document their observations and findings. 

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

"Life is more risk management, rather than exclusion of risks." -Walter Wriston. Scholars use provided mortality data to determine how likely it is a person will die from a particular cause. They compare the data to the perception of the...

The seventh segment in an eight-part unit promotes the idea of concentrating the sun to increase the power of a photovoltaic panel. Pupils learn about devices used such as reflectors or lenses.

Concentrate to determine the best reflector design. Pairs use the engineering design process to build a reflector to increase the current output of a photovotaic panel. Teams arrive at a final design and present it to the class along...

How temperature affects the efficiency of a solar panel is the focus of the third in a series of eight resources that presents how engineers are able to control the temperatures of photovoltaic panels. Class members find out how the...

The sun will continue to rise in the east and set in the west, no matter what. The first instructional activity in a series of eight introduces the class to solar angles. It makes connections between a person's latitude and the angle of...
