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.

In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

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

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

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

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, learners model a population of deer and see how the number of deer changes over time.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.
