Despite being close neighbors, these two large islands in the Mediterranean have distinctly different cheese traditions. While sampling Corsica’s renowned Brocciu, a soft ewe’s milk cheese, Will is introduced to a traditional version ripened with maggots. After a short ferry ride and a drive into the beautiful mountains of Sardinia, he meets a rock star shepherd and discovers an ancient curd cheese matured in a goat’s stomach, before exploring authentic Pecorino Fiore Sardo, an exceptional cheese hand-made by shepherds then smoked over an open fire.

This upper Midwest state is famous for its ‘cheese heads’ and proudly declares itself America’s Dairyland because it produces more cheese than any other state in the USA. Since the 1950s, most of the original traditional cheese types have been replaced by bland and predictable mass-produced Swiss and Cheddar. Will visits several exciting new farmstead cheese producers, including Uplands Cheese Company, before meeting Willi Lehner at Bleu Mont Dairy to see how he ripens cheese in an underground cave. Finally, Will heads for the hills to look at Hidden Springs Creamery, where a new organic ewe’s milk cheese is being made with the help of local Amish farmers.

Two clear liquids are mixed together and the audience is told to watch closely... "Don't take your eyes off the liquid or you'll miss it!" Then, in a flash, the water changes to ink (or so they think!). Clock reactions like this never fail to capture the students attention, and the Iodine Clock Reaction is one of the most startling chemical demonstrations you'll ever see. How did that happen? is almost always the reaction, and when students ask How?, theyre ready to learn.

In this video produced for Teachers' Domain, learn about MIT professor Cathy Drennan's research into microorganisms that remove carbon dioxide, a greenhouse gas, from the atmosphere.

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.

Learn the basics of gas with this informative video. Gases are compressible, they diffuse and expand to occupy the volume of their container fully.

Chemical reactions may be either visible or seemingly transparent, and the rates of reaction are dependent on several different things. This video demonstrates how temperature can be both a critical determinant or outcome, and the use of catalysts in speeding up reactions.

Although some chemical reactions appear transparent to the eye, changes in temperature may be occurring. Both endothermic and exothermic reactions are demonstrated.

The amount of time required to observe reactions when mixing different reactants together can be influenced by either the concentration of elements in the reactant, or the starting temperature of the reactant.

Catalysts contribute to chemical reactions but are not used up in the reaction.

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.

The Cherokee Nation virtual field trip affords an in-depth look at the lives of the Cherokee Indians, from their first encounters with Europeans to events, such as the Gold Rush and the signing of the Indian Removal Act by Andrew Jackson, that led to their forced relocation to Indian Territory in 1838.

This problem includes a percent increase in one part with a percent decrease in the remaining and asks students to find the overall percent change. The problem may be solved using proportions or by reasoning through the computations or writing a set of equations.

Mission US is a role-playing game (RPG). In each mission you’ll step into the shoes of a young person during an important time period in US history. While your character and many of the characters in the game are fictional, they are based on the experiences of real people. (You will also encounter some actual historical figures and witness historical events in the game!) In this simularion, the year is 1866. You are Little Fox, a Northern Cheyenne boy. Can you help your tribe survive life on the Plains? Note: This game requires creating a free account login.
