Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

One of the first biotechnology breakthroughs occurred in 1982 with the creation of synthetic insulin. Young scientists learn about DNA technology with a presentation and accompanying worksheet. It focuses on DNA extraction and...

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...

Show your class how engineers use graphs to understand large and complex systems. The resource provides the beginnings of graph theory by introducing the class to set theory, graphs, and degree distributions of a graph. 

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson in the series of seven. Individuals work on practice problems with this law and...

What better way to introduce the idea of a sequence than with robots! An educational activity explains the classic Fibonacci sequence before pupils build and program a robot to move. Additionally, the activity challenges individuals to...

How different can 3-D and 2-D really be? An engineering resource provides an explanation about the importance of two-dimensional technical drawings. Several samples show how to create multi-view drawings from pictorials and...

Watch red cabbage juice turn green. Pupils first watch a video that takes them through the process of creating red cabbage juice. They then add various solids and liquids to the juice and use the color change to determine whether the...

Which search engine is best? The last lab in a unit of five leads the class to investigate search engines. Working in groups, individuals read and discuss articles related to searching the Internet. Pupils develop suggestions that...

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Make fast food restaurants even faster. Groups consider trade-offs when maximizing efficiency in fast food restaurants. Restructuring schedules and floor plans, as well reassigning job duties, all fall under this directive.  

Mix up your lessons with a resource on mixed-media structures. Scholars design a structure out of paper, balloons, and string that will lift a pencil to the greatest height; they construct the structure at a later time. 

Learn how to find things quickly and efficiently on the Internet. The lesson teaches how search engines work and how to efficiently use them. It includes an activity where groups develop search queries to find sites using given criteria.

What do logarithms have to do with bone density? Scholars learn that the equation for bone density includes logarithms. The majority of the third lesson of seven is devoted to logarithms and their properties.

Experiment with 3-D glasses to learn about stereo images and virtual reality. Scholars look at various images to determine if green/red or red/cyan glasses are preferable. They determine distances between images using the 3-D glasses and...

Zero in on an interesting resource involving radar technology. Groups construct a radar sensing unit and learn to calibrate the system. Using the radar system and the Pythagorean Theorem, they calculate distances between objects.

The sky's the limit when learning about engineering. Future engineers conduct an activity to learn about forces associated with skyscrapers. They design and build a model of a skyscraper from basic household materials, then test their...

Biotechnology changes lives every day, but how did it all start? Learn about Cohen and Boyer's technique for recombinant DNA and the founding of this new scientific study. Then, scholars use the online interactive to discover how Hanahan...

Water, water, everywhere, but pollution is a major problem. Scholars design a filtration device or process that removes dirt and other particles from water. They use various household objects such as marbles, cotton balls, or coffee...

Shake, rattle, and learn! Future engineers build structures out of toothpicks or spaghetti sticks, using marshmallows as connectors. They then use a homemade shake table to test the sturdiness of their creations.

Two-axis rotations ... twice the fun as one-axis rotations! The last installment of a five-part module teaches scholars how to conduct two-axis rotations. They create isometric drawings before and after the rotations.

A little wind shouldn't hurt a building. Given three sheets of paper and six feet of tape, scholars create a structure that can withstand wind and hold up a weight. They conduct tests using a fan and decide on any improvements to make...

Take a swing at a fun activity. Pupils first watch a video that introduces the concept of elasticity in association with tennis rackets. They then design their own rackets and build them out of available materials.

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...
