In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this activity, learners will experiment with textures, shapes, and materials and create their own unique masterpieces.

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.

In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

In this activity, learners take their own pulse and explore how heart rate is affected by various activities.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this activity, learners overlap the three primary colors to see how all other colors are made.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

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.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this activity, learners will explore how and why weight distribution works.

In this activity, learners work in teams to simulate the process used by Global Positioning Systems (GPS) to determine the location of a fallen meteorite in Antarctica.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners make their own binary code bracelets by translating their initials into 0s and 1s represented by beads of 2 different colors.

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.
