Overview:
On this webpage you will find OER Chemistry textbooks along with supplemental materials and a few lecture videos.
The purpose of these discipline-specific pages is to display content that might be of interest to faculty who are considering adopting open educational resources for use in their classes. This list of content is by no means exhaustive. The nature of open educational resources is very collaborative and it is in that spirit that we encourage any comments about the content featured on this page or recommendations of content that are not already listed here.
Scientific data and tools should, as much as possible, be free as in beer and free as in freedom. The vast majority of science today is paid for by taxpayer-funded grants; at the same time, the incredible successes of science are strong evidence for the benefit of collaboration in knowledgable pursuits. Within the scientific academy, sharing of expertise, data, tools, etc. is prolific, but only recently with the rise of the Open Access movement has this sharing come to embrace the public. Even though most research data is never shared, both the public and even scientists in their own fields are often unaware of just much data, tools, and other resources are made freely available for analysis! This list is a small attempt at bringing light to data repositories and computational science tools that are often siloed according to each scientific discipline, in the hopes of spurring along both public and professional contributions to science.
This Force and motion Roller Coaster activity was done with my 5th grade class and they enjoyed it. It took longer than a normal science period but was a fun end of the year activity to help students stay engaged to their learning.

College Physics is organized such that topics are introduced conceptually with a steady progression to precise definitions and analytical applications. The analytical aspect (problem solving) is tied back to the conceptual before moving on to another topic. Each introductory chapter, for example, opens with an engaging photograph relevant to the subject of the chapter and interesting applications that are easy for most students to visualize.
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"A new addition to the International Space Station marks the beginning of exciting new explorations of exotic matter. This is BECCAL, the Bose-Einstein Condensate and Cold Atom Laboratory. A joint venture between NASA and the German Aerospace Center, BECCAL will enable scientists across the globe to eliminate one pesky force that plagues earthbound experiments: gravity. A Bose-Einstein condensate is a state of matter formed by cooling a gas of extremely low density to just above absolute zero. Systems like this enable scientists to study aspects of quantum mechanics on a relatively big scale, and could hold the key to bridging quantum mechanics to general relativity. Methods for generating Bose-Einstein condensates vary according to how they trap atoms, using either optics or magnets to do the trick. But typical experiments are hampered by the force of gravity. In a standard setup, gravity deforms optical and magnetic traps..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Students use their senses to describe what the weather is doing and predict what it might do next. After gaining a basic understanding of weather patterns, students act as state park engineers and design/build "backyard weather stations" to gather data to make actual weather forecasts.
Students are introduced to the concept of engineering biological organisms and studying their growth to be able to identify periods of fast and slow growth. They learn that bacteria are found everywhere, including on the surfaces of our hands. Student groups study three different conditions under which bacteria are found and compare the growth of the individual bacteria from each source. In addition to monitoring the quantity of bacteria from differ conditions, they record the growth of bacteria over time, which is an excellent tool to study binary fission and the reproduction of unicellular organisms.
In this experiment, two chemicals that can be found around the house will be mixed within a plastic baggie, and several chemical changes will be observed.
In this video, NOAA's Deke Arndt, Chief of the Climate Monitoring Branch at the National Climatic Data Center, recaps the temperature and precipitation data for the continental US in summer 2012. It describes how these conditions have led to drought and reduced crop yields.
This lecture/activity on force will further a students' understanding of forces on an object, as well as the difference between a balanced and unbalanced forces.
How do we find out whether the forces acting on an object are balanced or unbalanced? Learn in this video from the "Forces and Motion" chapter of the Virtual School GCSE / K12 Physics.

Play with objects on a teeter totter to learn about balance. Test what you've learned by trying the Balance Challenge game.
This webpage from Exploratorium provides an activity that demonstrates the Bernoulli principle with readily available materials. In this activity a table tennis ball is levitated in a stream of air from a vacuum cleaner. The site provides an explanation of what happens, asks questions about the activity, and also describes applications to flight. This activity is part of Exploratorium's Science Snacks series.
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!
In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it. Learners discover it is easier to balance a wooden dowel on the tip of their fingers when a lump of clay is near the top of the stick. Use this activity to introduce learners to rotational inertia.
