Design Step 3: Brainstorm Possible Solutions
Our young scientists have now specifically identified a problem, and this step helps them think of possible solutions. An outline, including guidelines, for brainstorming helps scholars stay on the right path. The resource includes...

Optimizing Pencils in a Tray
What do you call a story about a broken pencil? Pointless. Scholars may not be telling stories when using the resource, but they are solving optimization problems involving the maximum number of pencils that can fit on a tray. They...
Teach Engineering
Statistical Analysis of Flexible Circuits
Scholars connect statistical analysis with flexible electric circuits. They first learn about flexible circuits and their applications through a PowerPoint presentation and then consider how the fabrication process for these circuits...
Teach Engineering
Fun Look at Material Science
Introduce materials science with a class demonstration. After showing a PowerPoint presentation on materials and their properties, instructors provide a ceramic tile, a Popsicle stick, a paper clip, and a plastic bag as examples of...
Teach Engineering
Battle of the Beams
Make the strongest beam possible using taffy? Groups mold a taffy-water mixture into a beam and a reinforcing material of their choice. To finish the final installment of a two-part series, participants test its strength by adding...
Teach Engineering
Close Encounters of the Polymer Kind
A PowerPoint presents features of polymers and two of its categories (thermoplastics and thermosets). Instructors conduct demonstrations to illustrate the Weissenberg Effect and the Barus & Kaye Effects of polymers in the first of...
DiscoverE
Paper Tower
Read all about it! Challenge your class to build taller and stronger. Newspapers provide the means to build towers in a simple activity. Scholars try to build as tall a tower as possible with just two sheets of newspaper.
Teach Engineering
Corn for Fuel?!
Can corn power the world? Young scientists learn about how corn and other plants can provide renewable biofuels in the second of nine lessons. They set up an experiment to investigate how different variables affect plant growth. All of...
Teach Engineering
Sudsy Cells
Let's hope that your soap is doing what it's supposed to! The second of six installments in the Cells unit has scholars perform an experiment cultivating bacteria in Petri dishes. They test soaps and detergents to see which is most...

What Floats Your Boat?
Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...
Teach Engineering
Are We Alone?
Find an answer to the age-old debate of whether life exists on Mars. Groups determine criteria to help look for signs of life on Mars. The activity has the class simulate testing Martian soil samples for signs of life before drawing...
Curated OER
Strong as the Weakest Link
Students recognize that compression and tension forces are important considerations in building structures. They construct their own building structure using marshmellows and spaghetti to see which structure can hold the most weight.
Teach Engineering
Physics Tug of War
Slide books with a little assistance from Newton. Using books, groups create a demonstration of Newton's Second Law of motion. Pupils compare the distance traveled by one and two books when they apply a force to them.
Teach Engineering
The Great Gravity Escape
Groups simulate an orbit using a piece of string and a water balloon. Individuals spin in a circular path and calculate the balloon's velocity when the clothes pin can no longer hold onto the balloon.
Teach Engineering
Life Cycles
Breathe some life into product design. Pupils learn about the stages of product creation, use, and disposal—sometimes called a cradle-to-grave assessment. They see how this cycle relates to the life cycle of organisms.
Teach Engineering
Bridging the Gaps
The London Bridge should not have fallen down. And here's why. After a brief history of bridges and the three main types, class members are introduce to the concepts of tension and compression, the two main forces acting upon bridges.

Energy Forms, States and Conversions
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...
Teach Engineering
Energy Conversions
What energy conversions occur in the operation of a device? Small groups investigate devices and the energy conversions that occur. The groups create energy flow diagrams with added conversion processes for each of the devices...

Working with Wind Energy
Teams design and build a windmill, under budget, that can lift an object. The groups evaluate and reflect on their own design, then on those produced by other teams. The goal is to determine which design is the most...
Teach Engineering
Wetting and Contact Angle
Explore terminology related to water droplets. The sixth installment of a nine-part series teaches young scientists about wetting and contact angles between water droplets and surfaces. It also distinguishes between hydrophobic and...
Teach Engineering
Investigating Contact Angle
Discover the properties of water-loving and water-hating surfaces. In the seventh installment of a nine-part series, scholars explore hydrophilic and hydrophobic surfaces by conducting an experiment. They observe surface coatings,...
Teach Engineering
Bubbles and Biosensors
Bubbles aren't just for children. In the third installment of a seven-part series, teenagers use bubble solution to create bubbles and observe patterns of refraction on the bubble surfaces. Application of this concept to thin films in...
