Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Explore forces and motion as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces. Graphs show forces, energy and work.

It is Euro-centric to refer to all the Philosophies of Asia as “Eastern” as it unfairly groups the quite various Philosophies that developed in West Asia (Zoroastrianism), South Asia (Buddhism, Jainism, Hinduism, Sikhism), and East Asia (Ch’an Buddhism, Taoism, Confucianism, Shintoism) into a single unit that implies they are quite similar. Other than their relative geographic proximity, the various philosophies are, in many ways, more different than those philosophies that have been developed in Europe and the other parts of the world. This first Unit explores some of the older philosophical
viewpoints that underlie much of the philosophy that has been developed in East Asia, particularly China and Japan. These are Taoism, Confucianism, and the philosophical underpinnings of the Shinto religions.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.

Explore pressure under and above water. See how pressure changes as you change fluids, gravity, container shapes, and volume.

Software Carpentry lesson on how to use the shell to navigate the filesystem and write simple loops and scripts. The Unix shell has been around longer than most of its users have been alive. It has survived so long because it’s a power tool that allows people to do complex things with just a few keystrokes. More importantly, it helps them combine existing programs in new ways and automate repetitive tasks so they aren’t typing the same things over and over again. Use of the shell is fundamental to using a wide range of other powerful tools and computing resources (including “high-performance computing” supercomputers). These lessons will start you on a path towards using these resources effectively.

Undergraduate Learning Assistants can be used to supplement the instructor and/or Teaching Assistant during recitations. They may help facilitate productive group work on tutorial activities designed to help students develop conceptual understanding and problem-solving skills. In this example, we describe the use of Learning Assistants to support tutorials within recitation in two introductory science courses physics and chemistry.

Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern.
