Observing the Land Over the Seasons

Generate entertainment by assisting students in creating multiple chemical changes during the course of small experiments integrated into one packed lesson. Individuals observe examples of chemical changes as they occur and gather data...

Engage the class like never before as pupils learn to differentiate between multiple physical and chemical changes by conducting a list of small experiments, most often with household materials. They make observations and discuss the...

Students are able to observe chemcial and physical changes while producing a brilliant formation of foam. They are able to experience the use of an indicator in the reaction. Students record information based on their observations.

Embark on a year long investigation of the seasons with this 10-lesson earth science unit. After being introduced to different types of weather and the tools used to measure it, young scientists perform fun hands-on activities that teach...

Is there more to evaporation than just less liquid? Show young scientists the energy transformation that occurs during a phase change through a series of simple experiments. Lab partners place drops of water, ethanol, and ethoxyethane on...

Take part in a fun experiment and hold an impromptu bouncing contest with your class. Young scientists heat and cool balls before bouncing them to determine whether temperature changes affect how they bounce. The set of STEM lesson plans...

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...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

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...

Provides extensive evidence of the many ways scientists have observed and recorded climate change on a rapid, global scale. Lists different events observed, such as receding ice sheets and evidence in rocks, and presents graphs, images,...
