Fold a Crystal
Source Institutions
Rocks are made of minerals, and minerals often have crystal shapes. In this fun activity about geometry in nature, learners create their own crystal shapes out of paper.
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.
Box Ecology
Source Institutions
This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.
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.
Thinking in Three Dimensions
Source Institutions
In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.
Subtractive Paint Prints
Source Institutions
In this activity, learners of all ages will experiment with paint and printmaking.
Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.
Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.
Parabola Basketball
Source Institutions
In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.
Party Hat Symmetry
Source Institutions
In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.
Tessellations
Source Institutions
In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
Folding Matters
Source Institutions
In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.
Giant Museum: Create a Scale Model
Source Institutions
In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?
Spinning Blackboard
Source Institutions
Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.
Soaring Towers: Building with Recycled Materials
Source Institutions
In this activity, learners will build the highest tower they can out of recycled materials.
Kites
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.
Manufacturing Technologies: Making a Picture Frame
Source Institutions
Learners examine the manufacturing process while they make picture frames from cereal boxes.
Solidly Platonic
Source Institutions
In this activity, learners follow simple directions to explore and create platonic solids.
