Seventh graders research the origins of local electrical power and compare costs and methods of generation with other areas of the country or world.

Students investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for the...

Students experiment with states of matter with water and ice. In this states of matter lesson, students experiment to discover what happens to water as it freezes to become a solid, ice. They observe what happens when ice melts back to...

Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...

Students experiment with water and ice. In this states of matter lesson, students explore how water can change from a solid to a liquid and back again. They discuss and write about the results of the experiment in a science journal.

In this chemistry review worksheet, students review terms and concepts covered. Students practice metric conversions, factor labeling, temperature conversions, heat calculations, atomic structure, and gas laws. This worksheet has 3...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

A chemistry lesson presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

Students simulate the Earth's revolution around the sun using CEENBoT. In this earth science lesson students calculate the Earth's distance in AU and it's speed of revolution. They explain how the Earth's movement cause seasonal variation.

The Mars Global Surveyor spent two years creating a mineral map of the planet Mars using thermal emission spectrometry. To help young astronomers understand this remote sensing instrument, have them simulate how data is collected and...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...

Students identify and analyze what energy is and how they feel after moving around a lot. They identify other ways that they can acquire heat and if there is some sort of mechanism for storing energy. Finally, students construct their...

Students study solar energy.  For this renewable energy lesson students complete several lab activities using different controls and variables. 

Students investigate which metal is best to use as storage material in hydrogen cars. In this chemistry lesson, students differentiate endothermic and exothermic reactions. They write a reflection paragraph about what they learned in the...

Students work on problems in which they investigate conduction, convection, and radiation. They attempt to maintain the warmth in one can of soda while cooling the other as much as possible in a thirty minute period. They examine how...

Students experiment with a virtual solar cooker to discover the mathematical relationship among reflection, transmission and absorption. Then they actually build and test a solar cooker of their own invention.

Students investigate the properties of insulators by attempting to keep a cup of water from freezing, and once it is frozen, to keep it from melting. They conduct the experiment, record and analyze the results, and answer discussion...

Young scholars discover how a mini-solar panel is constructed by behaving like detectives. Students examine an actual solar panel, measure the solar panel's voltage and use drawings to describe what they observe before completing...

In this reflectivity instructional activity, students read about the absorption and reflectivity of light by different materials. Students solve 4 problems and determine the composition of given materials based on the amount of light...

Students calculate the amount of land required to produce the food eaten by an individual for one year. They compare the amount of land required to produce animal versus plant products. Students visualize the areas of land calculated.

Students observe how measurements are made with different instruments.  In this remote sensing instructional activity students investigate the physical state of surfaces including the surfaces of the solar system. 

Students learn examples of friction and drag, and suggest ways to reduce the impact of these forces. The equation that governs common frictional forces is introduced, and during a hands-on activity, students experimentally measure a...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...
