Spring Away!
The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value...

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...

Working with Watermills
Water is a powerful force; harness it through watermills. The task at hand is to create a simple watermill that functions in flowing water for at least three minutes. Scholars work together in teams to design and construct such a...

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.

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 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...
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
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...

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 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.

Understanding the Air through Data Analysis
Is there a correlation or causation relationship between air pollutants? Groups develop a hypothesis about the daily variation of air pollutants, specifically ozone and CO2. Using Excel to analyze the data, the groups evaluate their...

Thirsty for Gold
In the last portion of the six-part unit, teams perform an experiment with gold nanoparticles to determine which sport drink has the most electrolytes. The nanoparticles are used as chemical sensors and fluoresce in different wavelengths...

Induced EMF in a Coil Wire
Small groups investigate the interaction between a coil of wire and a magnet to create an electromagnetic field and observe the voltage they create. Through further interactions, they realize a conductor can be charged from the...

Tape Dispenser Challenge
Help your class get out of a sticky situation! Future engineers explore existing tape dispensers and then design a new system for dispensing tape. To put these systems to the test, they build and evaluate prototypes of their designs.

Product Dissection
Sometimes, taking things apart is more fun than putting things together. Groups of learners participate in a reverse engineering activity. They dissect a device of their choosing to see how it works—great hands-on learning from the...

Textbook Support Challenge
Textbooks are heavier than a sheet of paper, so how can paper hold up a textbook? Young engineers create a structure out of paper that can support a textbook. To add another wrinkle, they must stay within budget and time constraints.

Build a Roller Coaster
Let the good times roll as young thrill seekers build a roller coaster on school grounds. Future engineers design and build a roller coaster from flexible tubing. The roller coaster is for a marble, so there will be plenty of room to let...

Make Your Own Glue
You won't regret being stuck with this activity. By mixing a variety of household items, pupils create their own glue. They test the tensile strength of their glue and compare it to that of other adhesives.

Shaky Ground
You're on solid ground if you decide to use the resource. A simple activity has young engineers investigate the problem of liquefaction. A battery placed on dry sand will stay standing—but not if scholars add water to the cup.
