Students are introduced to the wave nature of light. In groups, they discuss Young's experiment and how diffraction and interference demonstrate the wave nature of light. Using examples, they show constructive and destructive...

Students measure the electric potential of 9 volt batteries using oscilloscopes. They draw a diagram of the front panel of the oscilloscope, conduct the experiment, and create a graph of voltage versus the number of batteries.

The interactive NOVA Polar Lab uses 360 degrees videos, interviews with scientists, and mini-games to send students on an immersive quest to understand how the poles are key to understanding Earth's climate -- past, present, and future.

Control the temperature and observe the impact on the motion and interactions between particles. Compare the interactions between nonpolar molecules and between polar molecules to see how polarity affects the boiling point of substances...

Observe polarization of a molecule.

A lab experiment in a series of experiments that investigates climate and the cryosphere. In this lab, students predict what Earth's climate may be like in the future based on models. They also predict how warming temperature and melting...

Explore how polarity affects molecular shape and charge.

Observe how molecules with hydrophilic and hydrophobic regions move in a mixture of oil and water, and pay attention to changes in potential energy over time. Move and rotate the molecules to see how they interact with their surrounding...

Simulations that explore different attractive forces between polar and non polar molecules.

Generate all polar, all nonpolar, or random proteins and observe how the protein folds in response to these molecular properties. Explore how the potential energy of the system changes over time to draw conclusions about how proteins...

Mix polar and nonpolar molecules together and observe changes in potential energy.

This is a Java tutorial showing the simple voltaic (or galvanic) electrical cell, which is the most basic type of "wet" cell and demonstrates the fundamental chemistry behind batteries.

The discovery of radio waves, which was widely seen as confirmation of James Clerk Maxwell's electromagnetic theory and paved the way for numerous advances in communication technology, was made by German physicist Heinrich Hertz. In the...

In this lab activity, students use brine shrimp as a substitute for krill to investigate how changes in environmental factors affect behavioral responses of krill in the unique environment of Antarctica.

A lab activity that introduces chromatography using markers, plus water and acetone as the solvents. Young scholars will take measurements to compare the mobile and stationary phases of the inks, and find the polarity of the inks and...

Play a game where you explore three scenes in Antarctica and find different types of animals: south polar skua, crabeater seal, emperor penguin, ice fish, leopard seal, killer whale, krill, adelie penguin, and weddell seal. After you...

Select an oil or water environment for molecules and observe how they are affected by interactions with their environment and each other.

Discover how peptides fold into stable conformations.

Explore the change in potential energy when molecules are separated from each other or broken apart.

Media-rich lesson in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...

This interactive site introduces students to concepts related to asbestos and how geologists analyze asbestos in building materials. The site is divided into three components: the geology of asbestos, identifying asbestos in the lab, and...

Experiment with mixing liquids and observing the volume they take up.
