Beat the Clock—Sorting Networks
Can multiple computers sort a list faster than one? Using a network drawn with chalk outside, groups move through the decision network to sort numbers. A series of extension questions come with the lesson and can be used in the same...
Teach Engineering
Start Networking!
Class members create their own social networks by collecting signatures before graphing the interactions with their fellow classmates. The degree distribution of the simulated social network is determined by calculating the degree of...

The Orange Game–Routing and Deadlock in Networks
How is data able to move in a congested network? Groups simulate moving data around a congested network by passing fruit around a circle, following specific rules, until everyone ends up with their own fruit. Extension activities...
Computer Science Unplugged
Tablets of Stone—Network Communication Protocols
Show your learners that the game of Telephone isn't the only way messages get mixed up. Pairs transform into the sender and receiver of a message sent in packets. At least one pupil is the messenger who either delivers, delays, or...
Computer Science Unplugged
Tourist Town—Dominating Sets
As an introduction to using a network to determine the fewest number of nodes that meet a given condition, small groups work together to determine the fewest number of ice cream vans, and their locations, to be able to serve the people...
Computer Science Unplugged
The Muddy City—Minimal Spanning Trees
What is the most efficient way to ensure everyone is connected? Individual pupils determine the least expensive route to pave roads in a fictional city. In doing so, they learn to find the minimal spanning tree for the situation. They...
Computer Science Unplugged
Ice Roads–Steiner Trees
As an introduction to Steiner Trees, class members are challenged to find the shortest paths to connect multiple points. The teacher introduces the problem by showing how to connect three points. Groups then go outside and construct a...

Energy Skate Park
Skate through a simulation on energy with an a activity that uses a computer simulation of a skater to reinforce the concept of conservation of energy. The resource guides pupils through scenarios using the computer simulation to...
National Nanotechnology Infrastructure Network
Hiding Behind the Mask
Microchips are a man-made wonder. Investigate the manufacturing wonder with a hands-on inquiry-based instructional activity. Scholars simulate the process of pattern transfer using photoresist. Their conclusion identifies how their...
Teach Engineering
Curb the Epidemic!
Class members use an applet on the Internet to simulate the spread of a disease. The simulation allows individuals to determine two nodes to vaccinate to limit the number of nodes infected. By running several simulations, scholars...
Curated OER
The Effect of Natural Selection on Genes, Traits and Individuals
Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Exploring Bone Mineral Density
Bone up on bone density. The second installment of the seven-part series has pupils read articles on two different websites to learn about bone density and its measurement, as well as X-rays and other imaging tools. A quiz assesses their...
Teach Engineering
Keepers of the Gate Journal and Brainstorm
The second segment of a seven-part series reviews the challenge of determining whether gargling with salt water helps a sore throat. Individuals journal what they know about the challenge and what they are trying to figure out to...
Teach Engineering
Windy Tunnel
Lift—it is about the wing's attack. Using a virtual wind tunnel, pupils investigate wing shape and angle of attack. Learners use worksheets to record their observations and to convert verbal relationships into mathematical equations in...
Teach Engineering
Stay in Shape
Using their knowledge of right triangles, pupils find out how far a ship is from a light house. Class members determine how far around the world a ship would be sailing at a constant speed.
