In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners determine whether thermal energy can be used for work.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this experiment, learners float colored ice cubes in hot and cold water.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this activity, learners explore Charles' Law in a syringe.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.
