This video segment explains centripetal force and illustrates how roller coasters rely on it to give you a thrilling ride.
This video segment adapted from NASA describes the basic characteristics of our star, the Sun.
Chemistry is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning.
Chemistry: Atoms First is a peer-reviewed, openly licensed introductory textbook produced through a collaborative publishing partnership between OpenStax and the University of Connecticut and UConn Undergraduate Student Government Association.
This title is an adaptation of the OpenStax Chemistry text and covers scope and sequence requirements of the two-semester general chemistry course. Reordered to fit an atoms first approach, this title introduces atomic and molecular structure much earlier than the traditional approach, delaying the introduction of more abstract material so students have time to acclimate to the study of chemistry. Chemistry: Atoms First also provides a basis for understanding the application of quantitative principles to the chemistry that underlies the entire course.
A work in progress, CK-12 Chemistry Teacher's Edition supports its Chemistry book covering: Matter; Atomic Structure; The Elements; Stoichiometry; Chemical Kinetics; Physical States of Matter; Thermodynamics; Nuclear and Organic Chemistry.
Using filter paper, students separate the dyes in Kool-Aid and food coloring and identify how many different compounds are used for the different colors. Students describe this process in terms of attraction of the molecules for water and paper.
This article continues an examination of each of the seven essential principles of climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured. Principle 2 covers the complex interactions among the components of the Earth system. The author discusses the scientific concepts underlying the interactions and expands the discussion with diagrams, photos, and online resources.
This interactive resource adapted from the National Park Service describes the different kinds of sediments that make up coastlines, with a focus on the variety in color, size, and sorting.
This video from NASA describes the detailed computer modeling used to predict that colliding neutron stars can produce gamma-ray bursts similar to those associated with black holes.
Watch the ZOOM cast find out how many balloons filled with air and then with water are required to support the weight of a cast member.
In this video segment, members of the ZOOM cast experiment by bending and folding sheets of paper into various shapes to see which shape will support the weight of a heavy book.
In this video segment from ZOOM, Hillary, from Randolph, MA, takes us on a tour of the columns in her neighborhood.

"Concept Development Studies in Chemistry" is an on-line textbook for an Introductory General Chemistry course. Each module develops a central concept in Chemistry from experimental observations and inductive reasoning. This approach complements an interactive or active learning teaching approach.
In this video segment adapted from ZOOM, two solar cookers are tested against a control to see which can cook a "s'more" faster.
This video from NASA features the Cosmic Origin Spectrograph (COS), which allows scientists to use spectrographic analysis to assess the composition of intergalactic material.
This interactive activity from ChemThink takes a closer look at a covalent bond--how it is formed and how the sharing of two electrons can keep atoms together.
In this interactive activity from the Building Big Web site, investigate dams in distress and decide if they should be repaired, removed, or left alone.
In this video segment adapted from ZOOM, cast members use a hair dryer to balance a ball in a stream of air, seemingly defying gravity.
In this video segment, the ZOOM cast is challenged to keep a ping pong ball in a funnel while the funnel is held upside down, seemingly defying gravity.
