Tic-Tac-Toe
Source Institutions
In this online version of the classic paper and pencil game, learners practice looking ahead to anticipate an opponent's move.
Rubber Band newton Scale
Source Institutions
In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).
Breaking the Code: Mayan Math
Source Institutions
This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.
Exploring Tessellations (Grades K-2)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.
Bean-Counter Evolution
Source Institutions
In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).
Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
Traveling Networks
Source Institutions
In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.
Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.
Rotating String Shapes
Source Institutions
In this group activity, learners make multi-sided polygons with string.
Peripheral Vision
Source Institutions
How far can you see out of the corner of your eye? Grab a partner and find out from the Exploratorium Science Snack.
Building Three-Dimensional (3D) Structures
Source Institutions
In this activity, learners practice drawing 3D structures in two dimensions. Learners draw cube stacks from five different points of view.
Balanced Budget Chemistry
Source Institutions
In this activity, learners balance chemical equations and discover the law of conservation of mass. Learners use coins to model molecules to balance the equations.
Skewers and Garden Poles
Source Institutions
In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
String Shapes
Source Institutions
In this activity, learners work together to make polygons (many-sided shapes) with string. Learners sit on the floor and hold onto a piece of string slid between their thumbs and index fingers.
Pocket Protractor
Source Institutions
In this activity, learners create angle-measuring devices--protractors--out of paper. Learners follow a series of steps to fold a square sheet of paper into a triangular Pocket Protractor.
