Copy Cats
Source Institutions
In this math activity, learners use what they know about shapes to copy a friend's hidden picture. Learners create a design out of pattern blocks and then hide their picture behind a screen.

Beach Buckets
Source Institutions
In this activity, learners explore a bucket of sand and beach objects.

Delivery Capsules
Source Institutions
Learners make self-assembled polymer spheres as a model for the lipid nanoparticles found in COVID-19 mRNA vaccines.

Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

Lava Lamps
Source Institutions
Learners observe working lava lamps to understand how they work (included in PDF link).

Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

Why do Hurricanes go Counterclockwise in the Northern Hemisphere?
Source Institutions
In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.
Pósteres Sobre el Espacio y Matemáticas
Source Institutions
Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en línea, en libros de consulta, y en calendarios y almanaques.

Flat Flashlight
Source Institutions
In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.

Oily Ice
Source Institutions
In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

Rubber Band Thermodynamics
Source Institutions
In this demonstration, learners explore the thermal properties of rubber. Learners investigate whether a rubber band contracts or expands when heated.

Lagging Sound
Source Institutions
In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

Ambiguous Cube
Source Institutions
In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.

Familiar Fossils
In this activity, learners explore different types of fossils by making their out of dough and objects from around the house.

Thumbs Away!
Source Institutions
Learners discover how important their thumbs are by attempting various tasks without them. After tying up their thumbs, learners attempt to legibly write their names or play catch with a tennis ball.

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

Great Openings: Slots, 35 Sense, and Hole In One
Source Institutions
These three short activities challenge groups to fit objects through paper and index cards: "Slots" presents the challenge for one learner to figure out which objects fit through a hole cut by another

Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

Make a Museum Collection at Home
Source Institutions
In this activity, learners will create their own museum collection using their favorite toys, drawings, or collection.
