In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

In this activity learners create patterns of hair beads.

In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity, learners create their own bird species using arts and crafts materials. The bird call recordings are not online so the introduction activity can't be done, but everything else can.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

In this activity, learners will learn how to knit using only their hands. Learners will explore patterns and fabrication as well as develop fine motor skills and patience through this activity.

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.

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.
