Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Tinkering with Tops
Source Institutions
In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.
Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.
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.
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.
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.
Rotating String Shapes
Source Institutions
In this group activity, learners make multi-sided polygons with string.
Bearings for Your Whirligig
Source Institutions
Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.
