In this activity, learners design miniature cars. Learners can create a telephone car, soccer car, merry-go-round car, or any other theme car they can imagine.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

In this activity, learners will explore two-dimensional shapes that are found in three-dimensional shapes. Learners will explore geometry, design, color and tool use through this activity.

In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity, learners will explore acid-base reactions and create their own bubbly results.

In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

This activity (on pages 10-12 of the PDF) encourages learners to consider what makes living things different from non-living things.

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 will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this activity, learners build a seesaw powered by magnets.

In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.
