Hot Equator, Cold Poles
Source Institutions
In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.
Glaciers
Source Institutions
In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.
Cookie Mining
Source Institutions
In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to
Subtractive Paint Prints
Source Institutions
In this activity, learners of all ages will experiment with paint and printmaking.
Morphing Butterfly
Source Institutions
In this activity, learners explore how nanosized structures can create brilliant color.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.
Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
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.
Magical Möbius
Source Institutions
In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.
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.
My Solar System
Source Institutions
In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.
Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Why Does the Moon Have Phases?
Source Institutions
In this activity, learners use a simple 3D model to discover why the Moon has phases.
Create Your Own Decoupage
Source Institutions
In this activity, learners will experiment with textures, shapes, and materials and create their own unique masterpieces.
"Baseketball": A Physicist Party Trick
Source Institutions
This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.
Magnification vs. Resolution: Can you see the flag on the Moon?
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Weight in Space
Source Institutions
In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.
