Searchable mineral database by Amethyst Galleries, Inc.: Students can search for minerals by class or alphabetically.
Mineral identification and properties using photographs by Richard Harwood of Black Hawk College — students can identify minerals photographs based on mineral property choices. Descriptions of each mineral include physical properties, crystallography information, common uses, and chemical formulas as well as pictures.
Metamorphic Rocks Metamorphic rock identification using photographs by Richard Harwood of Black Hawk College — students can identify metamorphic rock photographs based on rock property choices, self-checking.
Metamorphic rock identification by Dave Jessey and Don Tarman through Cal State Pomona — students can use this site as a step-by-step tutorial to identify metamorphic rock samples.
Sedimentary Rocks Sedimentary rock identification using photographs by Richard Harwood of Black Hawk College — students can identify sedimentary rock photographs based on rock property choices, self-checking.Plate Tectonics Plate tectonics laboratory using plate motions 3 exercises by Richard Harwood of Black Hawk College — interactive maps showing movement relative movement of plates, are multiple choice and self-checking.Jules Verne Voyager - This is an interactive map developed by UNAVCO where students can add earthquakes, stress axes, volcanoes, or plate boundaries to the entire world or by country.Having learned earlier that all the atoms of an element are identical and are different from those of all other elements, students now come up against the idea that, on the contrary, atoms of the same element can differ in important ways. In this lesson, students will be asked to consider the case of when Frosty the Snowman met his demise began to melt.The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.
