Learners explore water's property of cohesion through two investigations.
In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.
This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.
In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.
Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.
In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.
In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.
In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.
Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.
In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.
Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.
Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.
In this physical activity, groups of learners act as blood cells traveling through the circulatory system.
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
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.
