Puzzled Partners
Source Institutions
In this web-based activity, learners try to figure out who in an online chat room has their matching puzzle piece.
Engineering Ups and Downs
Source Institutions
In this activity, learners explore the engineering and principles behind working elevators.
Popsicle Bridge
Source Institutions
In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
Tourist Town: Dominating Sets
Source Institutions
In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one
Building Tall
Source Institutions
In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.
The Turing Test: Conversations with Computers
Source Institutions
This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.
The Ladder of Life
Source Institutions
In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.
Community Wind Project
Source Institutions
In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.
Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.
Spaghetti Bridge
Source Institutions
Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Photolithography
Source Institutions
In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.
Bridge Building
Source Institutions
This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.
Cryptographic Protocols: The Peruvian Coin Flip
Source Institutions
This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d
Trail Impact Study
Source Institutions
In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.
Exploring Fabrication: Gummy Capsules
Source Institutions
In this activity, learners make self-assembled polymer spheres.
Artificial Intelligence: The Intelligent Piece of Paper
Source Institutions
This activity explores what it means for a computer to be intelligent and introduces the topic of what a computer program is and how everything computers do simply involves following instructions writ
Ice Roads: Steiner Trees
Source Institutions
In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.
Hydraulic Car
Source Institutions
In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.
Hovercraft
Source Institutions
In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.
