A share-a-thon is a place where teachers can voluntarily upload their files for other teachers to use. When a teacher submits a file, it is catalogued and placed into a database. To view more materials from the topic above or from different branches of science click here.
Rates Of Weathering
Students will design experiments to examine how changes in surface area and temperature affect a tablet of Alka-Seltzer.
Student will investigate the effects of size, shape and mass on the settling rates of objects. Plastic, glass, and clay beads.
Student will investigate the effects of size, shape and mass on the settling rates of objects. Lead, copper, steel, and aluminum.
Surface Area And Weathering Rates
Calculate the increase in surface area and check out how chewing candy influences rates of weathering.
The Journey's End
By the end of this exercise, the student will be able to describe how size, shape and density of sediment grains affects their rate of settling, describe the vertical arrangement of mixed material after being dumped in water.
The Gaia Theory
Use the data above to construct a graph of the changing percentage composition of Earth's atmosphere since the formation of the Earth.
Dichotomous Mineral Identification
You will use a dichotomous key for identification. Dichotomous keys are used for identification in a wide variety of subjects. You will need to use a different dichotomous key to identify minerals on the New lab portion of the regents (June 2005).
Igneous Rock Identification
Using your senses and the Scheme for Igneous Rock Identification found in your reference tables, you will be able to first classify then identify the environment of formation of a variety of different igneous rocks.
Metamorphic Rock Identification
Using your senses and the Scheme for Metamorphic Rock Identification, you will be able to first classify and identify the rocks and their environments of formation.
In this lab, you will follow the Mineral Identification Chart found in your reference tables (also provided here) to classify then identify a variety of different minerals.
