Quadratic Functions: Toothpicks and Transformations
Source Institutions
In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

Trees: Recorders of Climate Change
Source Institutions
In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

Breaking Beams
Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.

Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

Built in Stopwatch
Source Institutions
In this activity (3rd on the page), learners investigate circadian rhythms by examining how well people do with estimating time.

Solving Linear Equations: The Yo-Yo Problem
Source Institutions
In this math lesson, learners explore linear patterns, write a pattern in symbolic form, and solve linear equations using algebra tiles, symbolic manipulation, and a graphing calculator.

Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

Drawing Conclusions
Source Institutions
In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

Making Map Projections
Source Institutions
In this activity about cartography, learners work in teams to create two different map projections: a planar (or polar) and a cylindrical (or Mercator) projection.

Estimation
Source Institutions
In this online activity, learners will explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement.

Honeycomb Geometry
Source Institutions
In this activity, learners will build a honeycomb. Learners will investigate how the shape of the honeycomb develops. Activity includes step-by-step instructions and extension ideas.

Exponential Models: Rhinos and M&M’s ®
Source Institutions
In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

Sweetly Balanced Equations
Source Institutions
In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

Arithmetic
Source Institutions
In this online activity, learners will brush up on their multiplication, division, and factoring skills with this exciting game.

The Muddy City: Minimal Spanning Trees
Source Institutions
In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

Mirror-Tracing
Source Institutions
This mirror-tracing activity related to proprioception is a visual and motor test that involves learning a new motor skill.

Toilet Paper Solar System
Source Institutions
In this activity, learners build a scale model of the solar system using a roll of toilet paper.

Model Wind Tunnel
Source Institutions
In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.
