High schoolers investigate the wavelengths of spectra lines for common atoms. In this atomic emission spectra lesson plan, students use a transformer and diffraction grating to observe the emission spectra of various atoms. They find the...

Students construct models of hydrocarbon molecules using candy and toothpicks. In this hydrocarbons lesson plan, students are given a sheet with the molecular formulas of hydrocarbons. As a group, they construct each molecule using...

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Students create a model of the birth of a star and demonstrate the stages of the star's lifecycle.  In this star lifecycle instructional activity, students mix flour and water in a jar to model the birth of a star, then role-play...

Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

Students construct models of the way water molecules arrange themselves in three physical states - solid, liquid, and gas. They explain the molecular behavior of ice, water, and water vapor.

Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

Students study hydrocarbon gases and chemical equations. In this hydrocarbon gases lesson, students work in groups complete a molecular formula worksheet and review alkane prefixes. Students complete molecular models, balance chemical...

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Pupils examine their eating habits and experience analyzing data and drawing conclusions. They construct models of the molecular backbone of saturated and unsaturated fats. In addition, they examine the labels of their food, record the...

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 participate in an angular solution of hydrogen activity. Using this activity, students also illustrate eigenvalue problems applied in mathematics. They explore Schrodinger's equation and particle wave duality.

Learners develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Learners work in teams and each...

Students decompose glucose and write an equation for the reaction. In this decomposition reaction lesson plan, students burn a sample of glucose and test the products for water using cobalt chloride paper. They write a balanced equation...

Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Students cuminate their study of molecular structure and bonding with this activity.

Students analyze a variety of cooking oils to determine the amount and types of fats included in each.

Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...
