Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

How does water activity play a role in food spoilage? First, the learners think about which types of foods would be best to take on a backpacking trip based on the water activity of different foods. It then walks through why water...

Third graders study different bodies of water and how they fit into the water cycle. They explain that materials exist in different states (solid, liquid and gas) and change from one to another, that there are systems, order, and...

Students discover the horrible situation of water shortages that many people face by completing Peace Corps activities.  In this global health lesson, students analyze and discuss photographs of people in Africa struggling to find...

Find an answer to the age-old debate of whether life exists on Mars. Groups determine criteria to help look for signs of life on Mars. The activity has the class simulate testing Martian soil samples for signs of life before drawing...

Did you know when you mix the reactants sulfur, tungsten, and silver, you get the products SWAg? The simulation begins with making sandwiches, to show pupils reactants and products of something familiar. They then can make water,...

Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.

Trying to learn through diffusion rather than simply studying the material rarely works for scholars. This simulation helps make learning diffusion fun. Pupils add a drop of dye to water and observe the diffusion as the molecules bounce...

Fifth graders investigate concentrated and diluted solutions by conducting a taste test.  In this dilution lesson, 5th graders examine the concentration of different juices samples by tasting them and recording their observations....

Fifth graders conduct an investigation into water purification during a role play situation in an Amazon Rainforest. They design a scientific experiment for cleaning and filtering water.

Five individuals in the class are "infected" with cholera! The rest of the class serves as investigators to discover the source of the outbreak. They test drinking fountains around campus for contamination. You, of course, will secretly...

Students work as scientists to simulate testing on soil, plants, and water for foreign chemicals through this series of experiments.

Students participate in a mock fire escape plan in this lesson. They identify the reasons for remaining calm, closing doors, ad testing doors between rooms and the main exits. They also watch a experiment that demonstrates what fire...

Fourth graders conduct an experiment demonstrating the effects of water and air temperature on precipitation. They create graphs demonstrating their findings using Claris Works for Kids.

Young scholars test the pH of soil samples they collected from the field trip. In this chemistry lesson, students differentiate acids and bases. They write a lab report about the experiment.

Students identify five senses, and use their senses of touch, sight, hearing, smell, and taste to distinguish different objects, sounds, smells and tastes, and write their answers in the booklet.

Students investigate the environment by examining mineral characteristics.  In this mineral lesson, students perform scientific observations in groups in which they identify minerals found in everyday objects by using a...

Students dramatize a two act play in which scene one depicts the story of Lazzaro Spallanzani and the second act deal with Louis Pasteur and his refutation of spontaneous generation.

Learners participate in a demonstration in which they must attempt to suck liquid from varying containers with straws of varying sizes. They discuss the concept of coevolution and see why this activity illustrate the coevolution of...
