Quantum Dots and Colors
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 color...
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...

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...
Exploratorium
Oil Spot Photometer
Are these two light sources the same? Groups use a white card and a little cooking oil to create a photometer that allows for the comparison of two lights. The Inverse Square Law provides a way to calculate the actual difference in...

STEM Activities for Middle School Students
Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...
National Sailing Hall of Fame
Sailboat Design Requirements
Sailboat design requires more than a half-circle and triangle sketch. After viewing a slideshow presentation that outlines the requirements for sailboat design, learners draw a design, perform the needed calculations, and write a paper...
Exploratorium
Groovy Sounds
Make music. Class members construct a simple record player using a paper cone and a pin. The resource provides a description of what is happening and why listeners can hear the sounds through the cone.
Teach Engineering
Nanotechnology as a Whole
It's a small (nanotechnology) world after all! The first segment of a six-part series gives an overview of nanotechnology, its principles and applications, and shares some of the engineering applications of nanotechnology. A presentation...
Teach Engineering
Challenges of Laparoscopic Surgery
Get some laparoscopic training without the pain with an activity that challenges class members to find out what it is like to perform laparoscopic surgery. Teams perform three different tasks and quantify their performance. The activity...
Teach Engineering
Preconditioning Balloons: Viscoelastic Biomedical Experiments
What does stretching a balloon have to do with equilibrium? Groups explore preconditioning by stretching a balloon to a point of equilibrium. They then measure the amount of force required to stretch the balloon to the same point several...
Teach Engineering
Imagining DNA Structure
Let's get a closer look at DNA and other molecular structures. The first instructional activity in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The...
Drexel University
Learning Roomba Module 3: Controlling Movement
Look at it go. The resource, the third in a series of five using a Roomba, explains the different types of movements a Roomba makes, then challenges pupils to create computer codes that will cause the Roomba to travel specific paths.
PBS
Invisible Force
Investigate invisible forces. Young engineers design a setup that changes the direction of a steel ball using a magnetic force. The purpose of the setup is to model the gravitational pull of spacecraft by planetary bodies.
Teach Engineering
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
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...
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...
Teach Engineering
Algae: Tiny Plants with Big Energy Potential
My, what big energy potential you have! Scholars learn about the energy potential of using algae as a biofuel. A PowerPoint presentation first describes the structure of algae and then how researchers use algae as biofuel to produce energy.
Curated OER
Ecosystem Services - Water Purification
Students see that ecosystems provide services to people that are essential to life as we know it. Reporters (drops of water) could interview the trees and soil in the surrounding ecosystems for news stories on how they helped keep the...
Curated OER
Water Purification
Students use the example of natural water purification to show that healthy ecosystems provide services to people that are essential to life as we know it.
Curated OER
Rover Landing Design Challenge
Learners examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.
Curated OER
Study of Animals
Third graders use the internet to research about an animal. After watching a demonstration, they follow the same steps to gain access to the internet as their teacher and find a picture of their animal to print. They complete a worksheet...
