Water Quality and Temperature

Physical science scholars discover an array of heat sources. They experiment to connect radiation to heat. They begin to understand thermal equilibrium. Then, they test to see if mass affects the rate of temperature change. Choose a few,...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

Students investigate the climate changes occurring locally, regionally and globally over the last one hundred years. They brainstorm and predict whether the current year's weather was warmer or colder than last year then check the...

An extensive investigation of the Earth's climate changes awaits your environmental science classes. This top-notch presentation begins by looking at the history of Earth's climate and then predicts the impact on each major terrestrial...

Does increasing temperature increase the rate of a chemical reaction? Junior chemists examine the effects of temperature on reaction rate using an engaging interactive. Pupils select the temperature of the reaction vessel, then observe...

Students examine NASA satellite observations of surface temperature and investigate the seasonal changes of land and water temperature.

Students investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction...

While clouds may not make for the most enjoyable weather, they play an important role when it comes to regulating the temperature of the earth. Watch this video and learn how these giant masses of water droplets actually help to cool the...

Many scholars know weight is actually a measure of gravity, so what is temperature? The video explains that temperature is a measure of kinetic energy. It connects the concept of how water evaporates when heated with how water evaporates...

A one-degree change in the earth's climate does not seem like a problem, but the rate at which our climate is changing is frightening. Of all the recorded temperature changes, our planet is currently warmer than it has ever been. If the...
