Edible Rovers
The good thing about building this rover is you get to eat it afterwards. Pairs determine rover parts they want to include in their design based upon their cost and usefulness. The teams design their rovers, build them from edible...
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.
Khan Academy
Challenge: Mickey Mouse Ears
My, what big ears you have! Novice JavaScript programmers adjust Mickey's ears to be proportional with his face and any changes to it. The key is to use variable expressions so that the values used are dependent upon the variable that...
Khan Academy
Bonus Project: Custom Clothing
Clothing design, do you know any teenagers that are interested in that? How about mixing what they have learned about JavaScript programing and the creativity of designing a piece of clothing? This activity does just that. Practice the...
PBS
Heart to Heart
Study heart health and math in one activity. After measuring their resting heart rates by finding the pulse in their wrists, learners build a stethoscope to listen to their heart rate, and note the differences between the two methods.
Rainforest Alliance
Sounds of the Rainforest
Do you hear what I hear? Encourage scholars to use their listening skills and participate in a series of activities that demonstrate how the sense of hearing is crucial to the human and animal world. Activities guide learners on nature...

A Shot Under Pressure
You've got to pump it up! Using the equations for projectile motion and Bernoulli's Principle, class members calculate the water pressure in a water gun. The pupils collect data on the number of pumps and distance traveled in order to...
Teach Engineering
Tools and Equipment (Part 1)
Looking for the best inclined plane for the job? Groups calculate the theoretical mechanical advantage for four different inclined planes. They determine the actual mechanical advantage by measuring the amount of force needed for the...
Teach Engineering
Portable Wheelchair Ramp Challenge
Ramp up the engineering design process in your classroom with an activity that challenges teams to design, build, and test a small-scale portable wheelchair ramp. The class develops design requirements, and teams test their designs using...
Teach Engineering
Thinking Green!
Encourage your class to solve local environmental issues. Groups brainstorm environmental issues that are affecting the community, choose one they want to solve, and design a product or service to solve their chosen issue. They then...
Teach Engineering
Red Cabbage Chemistry
Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply.
Teach Engineering
Density Column Lab - Part 2
Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the liquids...
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
DNA Forensics and Color Pigments
Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.
Teach Engineering
Android App Development
Building an accelerometer app for your Android device. Groups develop an app that uses the accelerometer on an Android device. The purpose of the activity is to reinforce the programming design. The post activity assessment challenges...
Teach Engineering
Bridging to Polymers: Thermoset Lab
Investigate thermoset polymers through experimentation. In an effort to determine the strongest, most flexible mixture, groups conduct an experiment on different-ratio epoxy-amine polymers to finish the set of two lessons.
DiscoverE
Zip Line Challenge
Harness the awesome power of gravity. Scholars build a zip line to transport a ping-pong ball. The challenge is to get to the finish line in under four seconds. At that speed, individuals better be sure to strap on the harness!

Hidden Alarm
It's time to wake up! Young engineers build an electric circuit that will activate an alarm. The use of switches in the circuit is a must—because you don't want the alarm to keep beeping forever!
Teach Engineering
Human Power
How many humans does it take to power a light bulb? The 10th part of a 25-lesson Energy Systems and Solutions unit has learners conduct an experiment to calculate power. They then use the results to determine how many classmates they...
