Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation!

Lecture notes on limitations of the value at risk model, and conditinal value at risk models for financial risk management

Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them.

Content Area Literacy courses have long been a requirement in teacher education programs for pre-service teachers for the secondary level and, sometimes, for the elementary level. The 2020 World-class Instructional Design and Assessment (WIDA) Framework takes a genre approach that aligns well with the traditional Content Area Literacy courses in teacher preparation programs. WIDA argues for an educational approach that fosters (a) equity of opportunity and access, (b) integration of content and language, (c) collaboration among stakeholders, and (d) a functional approach to language development. This textbook examines the elements that make up the Simple View of Reading with adjustments made for the increasing Multilingual student population. Then, the text focuses on the Key Uses of Language (KLUs) developed by WIDA with examples of how these are employed in different Content Areas. The final chapters focus on the unique needs and benefits of Multilingual students within U.S. classrooms.

This curriculum, developed as the final project for the Creative Commons for Academic Librarians Certificate course, is designed for students in introductory Library and Information Science courses. The unit offers a broad overview of fundamental concepts in copyright, fair use, and open licensing. The materials include readings, multimedia resources, discussion questions, and practical assignments. The curriculum addresses real-world challenges faced by librarians, explores the nuances of open licenses, and guides students through hands-on activities, fostering a deeper understanding of copyright issues in the digital age.

Visualize the electrostatic force that two charges exert on each other. Observe how changing the sign and magnitude of the charges and the distance between them affects the electrostatic force.

In this lesson, students create a compass and apply their reasoning about magnetism to how compasses work to help us navigate around the globe while utilizing the Earth’s magnetic field.

With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.

The DISCOVER-AQ curriculum integrates real-word research with real-life learning to answer the question: What are the causes and effects of air quality issues and how do they affect human health and the environment?

In this lesson, students measure and compare the rate of a falling object (a penny) at different heights to learn about statistical error.

Simulate the original experiment that proved that electrons can behave as waves. Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability.

This video explains design of the Arecibo Message transmitted in the 1970s by SETI pioneers.

Why do objects like wood float in water? Does it depend on size? Create a custom object to explore the effects of mass and volume on density. Can you discover the relationship? Use the scale to measure the mass of an object, then hold the object under water to measure its volume. Can you identify all the mystery objects?

In this lesson, students will work in small groups to develop an idea to increase community resilience, utilizing Design Thinking.

Explore tunneling splitting in double well potentials. This classic problem describes many physical systems, including covalent bonds, Josephson junctions, and two-state systems such as spin 1/2 particles and ammonia molecules.

This jigsaw activity introduces students with Arctic weather data using a role-playing activity that has students read and interpret graphs while considering the optimal time to plan a research mission to the Arctic.
