In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this arts and crafts activity about animals and animal characteristics, learners will design animal hats and role-play as animals.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.

This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

This is an activity exploring color and color mixing.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

In this activity, learners will use bubble wrap to print patterns on paper and experiment with mixing colors.
