The video resource "Aromatics and Cyclic Compounds - Crash Course Chemistry #42" is included in the "Chemistry" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Arsenic is element number 33. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

The resource, "C-ROADS Overview Reference" included in "Lesson 2 Modeling Exercise with C-LEARN" is a part of "Unit 10 Mock Summit and Portfolio Capstone Finale" included in Energy & Sustainability ES - Course 4

We discuss the special properties of aspirin and make a sample of it.

Stakeholders of the Morro Bay National Estuary Program in California worked with resources from the EPA's Climate Ready Estuaries program to identify their climate risks. Their results helped them prioritize actions for building resilience.

An interactive map based on four decades of satellite images helps residents, resource managers, and stewards of the land anticipate and plan for coastal change.

Because of its radioactivity and short half life, Astatine is an element few chemists come into contact with. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

The video resource "Asteroids: Crash Course Astronomy #20" is included in the "Astronomy" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Astronomy is designed to meet the scope and sequence requirements of one- or two-semester introductory astronomy courses. The book begins with relevant scientific fundamentals and progresses through an exploration of the solar system, stars, galaxies, and cosmology. The Astronomy textbook builds student understanding through the use of relevant analogies, clear and non-technical explanations, and rich illustrations. Mathematics is included in a flexible manner to meet the needs of individual instructors.

The video resource "Astrophysics and Cosmology: Crash Course Physics #46" is included in the "Statistics" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Paul Andersen explains how the atmosphere surrounds the planet. The state of the atmosphere is climate and is affected by unequal heating, the Coriolis Effect, and the ocean. Convection cells and ENSO are discussed in detail.

This course explores the physical processes that control Earth's atmosphere, ocean, and climate. Quantitative methods for constructing mass and energy budgets. Topics include clouds, rain, severe storms, regional climate, the ozone layer, air pollution, ocean currents and productivity, the seasons, El Ni–o, the history of Earth's climate, global warming, energy, and water resources.

The resource "Atom Properties" is included in the Physics Fundamentals topic of the EICC Engineering Techology Simulations resource series. This series is segment of a Department of Labor grant awarded to the Eastern Iowa Community Colleges (EICC) of Clinton, Muscatine, and Scott.

The video resource "Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22" is included in the "Chemistry" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

In this video Paul Andersen explains how the atomic model has changed over time. A model is simply a theoretical construct of phenomenon and so when we receive new data we may have to refine our model. Ionization energy data resulted in the formation of a quantum model that more accurately reflected the atom.

Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but the neutrons are different. Some isotopes are radioactive and may decay over time. The rate of decay is the half-life and can be used to measure decay or time.

Neutron Stars are some of the strangest things in the Universe. Not quite massive enough to become black holes they are basically atoms as big as mountains with properties so extreme it's mind-blowing. And if you get too close to a neutron star you are in big trouble. The video "Atoms As Big As Mountains -Neutron Stars Explained" is a resource included in the Physics topic made available from the Kurzgesagt open educational resource series.

The resource "Atoms, Electrons, Photons, and Light" is included in the Physics Fundamentals topic of the EICC Engineering Techology Simulations resource series. This series is segment of a Department of Labor grant awarded to the Eastern Iowa Community Colleges (EICC) of Clinton, Muscatine, and Scott.
