When you have to flow, you have to flow. The instructional activity 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...

The second segment of a seven-part series reviews the challenge of determining whether gargling with salt water helps a sore throat. Individuals journal what they know about the challenge and what they are trying to figure out to...

It is plane to see that simple machines help reduce the force needed to perform a task.  This resource introduces three of the simple machines--the inclined plane, the wedge, and the screw, and  the formulas in order to be able...

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

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Log some practice with logarithms. A PowerPoint presentation provides a tutorial on the change of base formula involving natural logarithms and solving exponential equations with logarithms in the fourth installment of a seven-part...

What kind of design challenges are there in building structures to support rocket engines? The unit takes design teams through the process of building the lightest possible thrust support structure that can withstand the necessary forces...

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...

From 3-D cities to building bridges, young engineers engage in innovative STEM challenges that promote brainstorming and collaboration. Learners take on the roles of different types of engineers as well as become familiar...

Helmets not included! Scholars brainstorm adjustments and sensors to football helmets in an engineering design project to help prevent injuries, such as concussions and spinal injuries.

Engineering design projects serve as great opportunities for collaborative problem solving. In this case, students work in small groups designing, building, and eventually testing a structure that meets a teacher-specified objective. It...

Information on the biomedical use of nanotechnology, specifically in the detection and treatment of cancer, is the focus of a lesson that seems like it is out of a science fiction novel. Pupils learn about electrophoresis, which is used...

Help young researchers find credible sources online. Modeling with a Google search for information about Shakespeare’s Macbeth, use a computer projector or Smart Board to show class members how weak the top three search results are....

Elements, to the rescue! Scholars first review the periodic table, and then learn about the first 20 elements and their properties and uses in the fourth of six lessons in the Mixtures and Solutions unit. Applying their newfound...

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...

"By the hair on your chinny-chin-chin, I'll huff and I'll puff and I'll blow your house in," says the big, bad wolf! Engineering hopefuls are challenged to design and construct a hurricane-proof building from simple office and craft...

Navigate the ups and downs of learning about energy. Future engineers consider how potential and kinetic energy apply to roller coasters. They design a roller coaster of their own and then use computer design software to showcase their...

Even magicians can't make energy disappear. In a discussion-based activity, young scientists learn about energy forms and conversions. They see how energy is neither created nor destroyed; it just changes forms. This is the 11th...

If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

Take a very basic understanding of circuits and develop a strong understanding of the parts and function of a circuit. This activity is developed to be an independent exploration of circuits from the basics to series and parallel models....

Is your building a smart building? Pupils learn what makes a building smart and about the internet of things. After viewing several videos on the topic, they conduct an activity collecting data from sensors and brainstorm ways to improve...
