Biomass : energy from wood, garbage, and agricultural waste
This resource explores the non-renewable resource of Biomass. As a organic material, biomass stores sunlight in the form of chemical energy. Biomass fuels include wood, wood waste, straw, manure, sugar cane, and many other byproducts from a variety of agricultural processes. Other focal topics will include types of biomass and the carbon cycle. Copyright 2005 International Technology Education Association

In this activity, students will understand the following (1) gravity is the force of attraction that causes objects to fall toward the center of the earth, (2) air resistance, or air friction, can slow down the acceleration of a falling object, (3) the area 'fronting the wind' affects the amount of air resistance a falling object encounters, (4) terminal speed is the speed at which the downward pull of gravity is balanced by the equal and upward opposing force of air resistance for a falling obj

Three forces on a glider
A glider is a special kind of aircraft that has no engine. Paper airplanes are the most obvious example, but gliders come a wide range of sizes. Toy gliders, made of balsa wood or Styrofoam, are an excellent way for students to study the basics of aerodynamics. This resource discussed the historical applications of the glider design, its comparison to powered air vehicles, and its ability to generate lift.

The windmill (VM1)
This project requires designing blades for a windmill to be used in lifting weights. The activity involves assembly of the basic windmill as well as construction of, and adjustments to, the blades for optimum performance. Provides knowledge of static and dynamic friction, aerodynamics, and power calculations. Requires an understanding of horsepower and the difference between power and energy.

Measuring (Const)
The purpose of this lesson is to introduce students to measuring with both the Standard Ruler and the Metric Ruler. Six attached worksheets will give students practice on measuring. A PowerPoint slide show is provided to introduce the pieces of a ruler. Working with their partners, students will complete worksheets representing equal portions of the inch (i.e. 1/4 and 3/4, or 1/8, 3/8, 5/8, and 7/8). This lesson provides background information for teachers and instructional procedures. Copyright

Measurement fundamentals
This lesson is from a variety of online tutorials developed for the Virtual Machine Shop. This module explores the subject of measurement. Linear and angular measurement is discussed and the inch and metric systems of measurement are compared. The uniqueness of the machine shop fraction is reviewed and examples of pronunciation are given. Animations and sound clips are provided to enhance the user experience. Users will have access to library, menu, previous, and next links to navigate throughou

Geochemistry of Igneous Rocks
This website contains an abundance of data on the geochemistry of igneous rocks. The site provides very brief descriptions of many types of terrestrial and lunar igneous rocks, their regional distribution and classification, and examples of their geochemical trends and fingerprints. Graphs that plot the geochemical composition of both terrestrial and extraterrestrial igneous rocks are also featured. This site could be useful for upper level geology students doing independent research, as well as

General Classification of Igneous Rocks
These lecture notes are part of a series of lectures available on the geology department website at Tulane University. Topics covered include criteria for the classification of igneous rocks, field identification of minerals present in hand sample, thin section examination and chemical analysis. The general chemical classification covers silica content (silica saturation), aluminum saturation, and alkaline and subalkaline rocks. This resource is part of the Teaching Petrology collection. http://

External Symmetry of Crystals, 32 Crystal Classes
This site is a lecture by Dr. Stephen Nelson from Tulane University that explores the 32 possible combinations of symmetry operations that define the external symmetry of crystals. The lecture defines the six crystal systems (triclinic, monoclinic, orthorhombic, tetragonal, hexagonal, and isometric) and explains the derivation of the Hermann-Mauguin symbols (also called the international symbols) used to describe the crystal classes from the symmetry content. Tables and illustrations accompany t

A Classification of Metamorphic Rocks
This 24-slide PowerPoint presentation describes the classification of metamorphic rocks using texture and composition. Foliation, lineation, cleavage, schistosity, gneissose structure, hornfels, and granofels are discussed. Specific metamorphic rock types and modifying terms (porphyroblastic, spotted, augen, para-, ortho-) are defined and photographs of some are provided.
