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...

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.

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...

Concentrate This! Sugar or Salt...
Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Seeing All Sides: Orthographic Drawing
How can your draw three-dimensional figures on paper? The lesson shows pupils how to draw orthographic projections of three-dimensional figures composed of cubes. After viewing a PowerPoint presentation, they practice this skill with...
Teach Engineering
New Perspectives: Two-Axis Rotation
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.
Teach Engineering
Energy Perspectives
The data says ... the resource is great to use. Using Microsoft Excel, pupils analyze data from the US Department of Energy in the fifth lesson of a 25-part Energy Systems and Solutions unit. Each group looks at a different data set and...

Edible Algae Models
Sometimes it's okay to eat your science experiment. A hands-on activity has pupils create models for algae to learn about its cellular structure. The best part of the experiment? The resulting juice-filled gels are edible—yum!

Evaluating Sensors and the Impacts of Physiological Stress: Designing a Wearable Device for Rescue Workers
A long-term project has scholars consider ways in which sensors help monitor physiological stress levels of rescue workers. They design and create a portable device for this purpose. Techies to the rescue!
Teach Engineering
The Energy Problem
Think you can solve the energy problem? You'll first need to know about current energy use. Analyzing a set of circle graphs lets scholars see where energy consumption is the greatest, both by sector and by household use. They develop a...
Teach Engineering
Energy Resources and Systems
We've talked a lot about energy, but where does energy come from? Pupils brainstorm different energy sources through a class discussion to kick off the 14th installment of a 25-part Energy Systems and Solutions unit. They then research...
Teach Engineering
Introduction to Circuits and Ohm's Law
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....

Enough Energy? Play the Renew-a-Bead Game
Pairs simulate the energy usage of different countries by drawing beads from a bag, which contain different beginning ratios of non-renewable and renewable energy resources. The activity concludes with a series of questions to tie the...

The Internet Is for Everyone
What is this thing called the Internet? A KWL activity elicits what the class knows about how the Internet works. Then pupils read a copy of a memo about the need to keep the Internet open and accessible by everyone.
