Mr. Breed and his students create review and lab experiment podcasts in preparation for the New York State Regents exams in Earth science and chemistry.
Mr. Breed provides a comprehensive review of Chapter 16 in the textbook, which covers the chemistry of solutions. He describes various types of solutions and how they form. Mr. Breed also describes performing calculations involving molarity, molality, percent by mass and volume, dilutions, and boiling point elevation or freezing point depression.
In this episode of CheMatters, Mr. Breed describes some of the unique properties water possesses. He explains how solutions form and some of the various types of homogeneous and heterogeneous mixtures.

Mr. Breed discusses weathering, erosion, and deposition in the sixth episode of Let's Get Down to Earth... Science. In this podcast, Mr. Breed describes physical and chemical weathering and gives examples of each type. He also discusses various agents of erosion and how their action influences deposition of sediments. New music courtesy of the Podsafe Music Network is included. http://music.podshow.com
Mr. Breed provides a comprehensive review of Chapters 13 and 14 in the textbook, which covers the Kinetic Molecular Theory and how it describes the properties of solids, liquids, and gases. He then discusses using Charle's, Boyle's, and the Guy-Lussac Law. He also gives an example of how to use the Combined Gas Law on the New York State Chemistry Reference Tables.
Mr. Breed discusses Earth's history in the fifth episode of Let's Get Down to Earth... Science. In this podcast, Mr. Breed describes what fossils are and the various processes by which they form and are preserved for us to find. He also discusses the importance of fossils in understanding Earth's past. He then goes on to describe how various geologic principles can be used to determine the relative ages of rock layers and events in geologic cross-sections. Techniques for determining the absolute ages of rock samples are described and the idea of radioisotopes and half-lives are discussed. A brief summary of the geologic time periods in Earth's history wraps up this episode. Keep studying! The regents is just around the corner!
