Soap Bubble Shapes
Source Institutions
Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.
Find the Fat
Source Institutions
Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.
Life Size: Line 'em up!
Source Institutions
In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.
Paper Tape Motion Timer
Source Institutions
In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).
Height Sight
Source Institutions
In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.
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.
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.
Reflections
Source Institutions
In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.
Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.
Cut-Fold-Staple
Source Institutions
In this activity, learners discover how to rotate a flat shape into the third dimension. Learners draw and cut out a shape that has at least one straight edge on an index card.
Angle Hunting
Source Institutions
In this activity, learners use a hand-made protractor to measure angles they find in playground equipment.
Falling Rhythm
Source Institutions
Listen to the beat of gravity. By taking two strings with weights tied to them at different, yet uniform intervals, you can hear the uniformity (and rhythm) of gravity's accelerating pull.
Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.
Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.
Fantastic Four: A Math Card Game
Source Institutions
This is a game that is sure to sharpen players' basic math skills. Players must use four randomly selected numbers to create an equation that equals a fifth number.
Life Size: What's in a microbe?
Source Institutions
In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.
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.
Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.
Beyond Dominoes: Polyominoes
Source Institutions
In this activity, learners add squares to paper dominoes to make polyominoes.
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.
