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.

Incredible Shrinking Shapes
Source Institutions
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

Tiny Pants Photo Challenge
Source Institutions
In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

Greeting Card Boxes
Source Institutions
In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

Dye Like A Natural
Source Institutions
In this activity, learners stain fabrics--on purpose!

Soda Can Mirrors
Source Institutions
In this activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

The Four-Square Quilt
Source Institutions
In this activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

Making a Translation Tessellation
Source Institutions
In this activity, learners slide shapes to create unusual tiled patterns.

Simple Pop-Up Mechanisms
Source Institutions
In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

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.

Solidly Platonic
Source Institutions
In this activity, learners follow simple directions to explore and create platonic solids.

Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.

Three Circles of Pigments
Source Institutions
In this activity, learners overlap the three primary colors to see how all other colors are made.

Exploring Tessellations (Grades 6-8)
Source Institutions
In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

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.

Experimenting with Symmetry
Source Institutions
In this activity, learners use pattern blocks and mirrors to explore symmetry. Learners work in pairs and build mirror images of each other's designs.

Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

Secret Codon
Source Institutions
In this activity, "write" a secret message in genetic code as beads on a string.

Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

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.
