Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.

Students identify the periodic table trends and predict material properties. They also design and conduct simple experiments and test material properties. Finally, students compare and contrast material properties and that chemical...

Students understand how mineral deposits are formed and why they are not evenly dispersed. They create and describe three different precipitates from four solutions simulating mineral ore deposit formation in sedimentary rock.

Eighth graders observe evidence of chemical reactions.  In this chemical reactions lesson students study chemical processes and complete a lab activity. 

Students explain the role of stratospheric ozone and predict at least three ways in which depleted ozone would change her/his lifestyle. They then describe the process by which chlorine or bromine compounds can break down ozone molecules.

Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.

Students predict the shape of molecules using VSEPR theory. In this chemistry instructional activity, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.

Students calculate the values of electron binding energies. In this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.

Students examine pollutants and investigate air pollution emitted by a car in a year.  For this air pollution lesson students complete an activity and make calculations. 

Students explore Jupiter's magnetosphere. In this Jupiter lesson plan, students examine a diagram of the magnetic field that surrounds Jupiter.

Students plot earthquake and volcano data using a Compass Rose Plotting. They explain the relationship between plate movement and connection. They draw conclusions that earthquakes and volcanoes occur in predictable locations.

Students engage in a lesson that is concerned with the concept of water chemistry. They conduct research using a variety of resources. Students also consider an experiment to observe how water has the abiility to exist as three different...

Students compare Jupiter and Earth. In this Earth and space studies lesson, students compare the composition of Earth and Jupiter and analyze how the composition affects the rate at which the planets spin.

Students examine carbon dioxide and determine the impact of greenhouse gases on the earths spheres.  In this pollution lesson students complete a lab activity to see the impact of gases on the environment, 

Fourth graders improve their understanding of Graham's Law by using properties of gases to evaluate the rate of effusion of two compounds as they vaporize. They engage in a lab which elevates their understanding of the properties of gases.

Students articulate an explanation of photosynthesis. They identify problems they have with comprehension of how a plant gains mass. Students describe a historical experiment.

A module with animations, explanations, and questions about the importance of electrons in the structure of an atom. Understand the definition and locations of electrons in the atom. Explore the role of electrons in bonding, polarity,...

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...
