Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

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 build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

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.

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.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

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

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.
