Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life.
How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
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 activity, to learn about the biological needs of mosses, students will grow and maintain their own moss terrarium. Through daily maintenance and observation, students will identify those factors necessary for the successful cultivation of moss.
Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.
This unit from the Guyana ICT in Education for Teachers Course provides training so that teachers are able to identify key characteristics of classroom practices and specify how these characteristics serve to implement policies. (TL.1.a)
Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.)
This is the second module in our OER Academy that will provide participants with an introduction to OER discovery. We have designed these modules to first spark the learner's interest in the topics covered and then dig deeper into the content through presentations, storytelling, and demonstrations of the tools. We will offer opportunities for learners to practice exploring the resources and tools, and reflect on how they might use them in their work.
This Open Educational Resource (OER) manual instructs educators on how to begin creating OERs. It includes an overview of OERs, their alignment with UNESCO Sustainable Development Goals, their definition, creation, discovery and evaluation, accessibility, licencing, hosting and production, metadata, and OER hosting and curation.
Open Pedagogy is a collection of open practices in the classroom made possible by replacing commercial textbooks with open educational resources. These emerging practices enabled by open content licensing (and an open mindset) involve students in making decisions about their own learning experiences and contributing directly to global knowledge to impact not only other students but generate renewable value outside of the classroom.
This is a recording of a webinar presented by three faculty members and two students who have participated in open pedagogy projects that were enabled through the adoption of open education resources and open practices. Learn how students working with instructional designers and librarians have begun to help faculty adopt, create and implement open content across their campus.
Delve into a microscopic world working with models that show how electron waves can tunnel through certain types of barriers. Learn about the novel devices and apparatuses that have been invented using this concept. Discover how tunneling makes it possible for computers to run faster and for scientists to look more deeply into the microscopic world.
Outlines faculty engagement in year two of “School Librarians Advancing STEM Learning," a 3-year project (2015-2017), supported by a grant from IMLS, with the goal to extend a proven collaborative model to reach pre-service and in-service school librarians--and their STEM teacher colleagues as well as faculty in teacher education programs--in accelerating school librarian instructional expertise and leadership.
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.
This web page is an interactive physics problem on vector addition. The page explains the concept of breaking a vector into components and adding them together, and works through an example problem. The attached Java applet visualizes the problem. This is part of a collection of similar simulation-based student activities.
The Web-based Inquiry Science Environment (WISE) is a free on-line science learning environment for students in grades 4-12. In WISE, students work on exciting inquiry projects on topics such as genetically modified foods, earthquake prediction, and the deformed frogs mystery. Students learn about and respond to contemporary scientific controversies through designing, debating, and critiquing solutions, all via the internet. Curriculum projects are complete and ready to use in the classroom. The projects are designed to meet standards and complement existing science curricula. The Teacher Area lets instructors explore new projects and grade students' work on the web, as well as to collaborate with other teachers and researchers.
Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern.
