Third graders observe and reproduce the water cycle in their very own classroom. A simple, yet very effective, demonstration on how water evaporates is observed by the young scientists. They make observations and sketches in their...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

Students illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.

Students explore matter. They use a formula to measure the volume of matter.

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...

Students role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...

Students explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

Students practice spending money by completing math word sentences.  In this economics lesson, students utilize problem solving strategies to complete word problems written on the board involving making purchases with money....

Students simulate the Coriolis Effect to comprehend why winds in the Westerlies are prone to cyclonic and anti-cyclonic motion. They arrive at an explanation of processes that drive world wind patterns

Fifth graders complete a variety of activities surrounding European exploration of the New World. They research one explorer and write and present an essay or script in which they portray that explorer as he makes his final report to his...

Fourth graders play a game where they are trees gathering sun, water, and nutrients and CO2 represented by pieces of paper or poker chips. They record their collected requirements and graph how they grew as a forest.

Learners determine the differences between the crystallization of igneous and metamorphic rocks. They examine both liquid state and solid state crystallization.
