The Exploratorium

Cold Metal
Source Institutions
In this activity, learners discover that our hands are not reliable thermometers.

Make Your Own Telescope
Source Institutions
Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.

Carbon Configurations
Source Institutions
In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.

Pupil
Source Institutions
In this activity, learners explore their eye pupils and how they change.

Walking Polygons
Source Institutions
In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.

Spherical Reflections
Source Institutions
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.

Incredible Shrinking Shapes
Source Institutions
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

Electroplating
Source Institutions
In this electrochemistry activity, learners will explore two examples of electroplating.

Bicycle-Wheel Gyro
Source Institutions
In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.

Take It From The Top: How Does This Stack Up?
Source Institutions
In this activity, learners explore center of gravity, or balance point, of stacked blocks.
