Class members learn how to estimate the total costs involved to design and build a bridge by including design, material, equipment, and labor costs. The activity includes a discussion about the trade-off between cost and aesthetics.

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

Here is an activity that merges technology with life skills as individuals use Google Earth to explore the differences between coordinate systems and map projections. The self-guided worksheet is the fourth segment in a nine-part unit....

Individuals create a GIS data layer in Google Earth that displays information about where one might find seven different cryptids. The class members research to find data on cryptid sightings they can include in their data...

A research position becomes a modeling job. The introductory lesson in a series of nine presents the challenge of analyzing a set of bivariate data. The class brainstorms what the data may represent. Pupils must decide what is needed to...

It's not so straightforward — lines can model a variety of applications. Pupils experience linear relationships within the context of science, including Hooke's and Ohm's Laws. Class members got a taste of motion and speed from the...

Osteoporosis and family — notice the connection between the two. Pairs develop a brochure to educate the public about osteoporosis in the last portion of the six-part series. The teams draw on the information learned throughout the...

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

Elasticity and viscosity. Help your class understand the similarities and differences with an introduction to viscous fluids. After describing four types of fluid behaviors: shear thinning, shear thickening, Bringham plastic,...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

 The class must determine the magnetic properties of different materials, including aluminum and steel by sorting through materials using a magnet. Groups make a prediction on whether a material is magnetic and then perform...

Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...

Introduce your class to the idea of magnetic fields around electrical wires with an activity that provides the information about the direction of a magnetic field around a wire carrying an electric current.

Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is...

Take two pills and call me in the morning. The first instructional activity in a short unit of four introduces class members to delivery methods of medicines. The instruction introduces the question of which delivery method is best to...

Plop, plop, fizz, fizz, oh that one is the fastest. The teacher demonstration is the second part of a four-part series. The class observes how different pill types dissolve in simulated stomach acid. They determine which one dissolves...

When you have to flow, you have to flow. The lesson introduces class members to microfluidic devices and their uses in medicine. They watch a short video on how the diameter affects the rate of flow. The worksheet has individuals...

Can you beat the odds of cancer? In the first installment of a seven-part series, future biomedical engineers consider how to detect and diagnose cancer. An article on biosensors provides useful information toward this goal.

The second installment of a seven-part series focuses on the refraction of light and how it affects the colors we see. Learners consider how this concept connects to biosensors for cancer detection.

The plot thickens to get a functional understanding. After a short review of plotting points on the coordinate plane, class members learn the difference between functions and relations in the second lesson in a series of nine. They...

Let's get the herd to follow the rules. The activity associated with the second lesson in the unit introduces the class to the definition of a function. Individuals must gather in groups of zebras and rhinos defined by the general...

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...

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.
