Giant Lens
Source Institutions
In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

Doghouse Design
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

Race Around the Black Hole
Source Institutions
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.

Musical Coat Hangers
Source Institutions
Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

Mirror Messages
Source Institutions
In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

Equatorial Sundial
Source Institutions
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

Ocean Echolocation
Source Institutions
Use echolocation to find others and experience how whales’ senses have adapted to suit their environment. In pairs, learners are blindfolded and use containers filled with marbles to find each other.

Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

Super Sleuths
Source Institutions
In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

Dough Creatures
Source Institutions
In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.
Transparent Gelatin
Source Institutions
In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

Three Circles of Pigments
Source Institutions
In this activity, learners overlap the three primary colors to see how all other colors are made.

Sun Prints
Source Institutions
This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

Color Contrast
Source Institutions
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

Opti-Top
Source Institutions
In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

Waves and Tides
Source Institutions
In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

Dance Pad Mania
Source Institutions
Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.

Nanoparticle Stained Glass
Source Institutions
In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

Observing the Moon
Source Institutions
Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

Science of Sunblock
Source Institutions
This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl
