Foundation Information:
Steels are categorized into five groups: About 90% of steels are carbon steels. Carbon steels make machines, automobile bodies, structural steel for buildings, ship hulls, bed springs, and bobby pins. Alloy steels have a specified composition and contain larger amounts of manganese, silicon, and copper than carbon steels. Alloy steels make automobile gears and axles, roller skates, and carving knives. Most recently created steel. HSLA steels contain less of the more expensive alloys in alloy steels making them significantly cheaper. HSLA steels are stronger in bending and compression than a carbon steel of the same weight. HSLA steels make or are used to make freight cars, numerous new structures in buildings. HSLA steels also leave more space in a building itself because it take less HSLA steels to do the job of a carbon or alloy steel. Stainless Steels contain chromium, nickel, and other alloying elements that keep them bright and rust resistant especially if the stainless steel is acted on by corrosive acids, gases, and moisture. Stainless Steels are made for extreme conditions such as very high or low weight and temperature. Often stainless steels are used for decorative purposes because they are so shiny. Stainless Steels make for pipes and tanks in petroleum refineries and chemical plants, jet planes, space capsules, surgical equipment, silverware, and can be used to patch or replace broken bones. Tool Steels are fabricated into many types of tools or into the cutting and shaping parts of power-driven machinery for various manufacturing operations. Tool Steels contain alloying elements that give them extra strength, hardness, and resistance to wear.
 * Wood:** When it is in non-lumber form, wood consist of cellular ducts or tubes. These ducts carry water and dissolved materials from the roots to the leaves and the ducts are arranged somewhat vertically in the trunk. Wood is classified as either softwood or hardwood. Hardwood is wood from broad-leaved trees and softwood is wood from coniferous trees. Coniferous means that a tree bears evergreen leaves and cones. However, the terms hardwood and softwood have nothing to do with the actual hardness of the wood. Almost all of the lumber in the U.S. is softwood. Toughness is a measure of strength against sudden and repeated stress. Oak trees have is very strong when it comes to bending and weak when it comes to compression. Redwood is the opposite, strong in compression and weak in bending.
 * Steel:** Steel is an alloy of carbon and iron and is sometimes mixed with other elements. Steel, in the past, was made by heating a mass of iron ore or charcoal in a forge or furnace having a forced draft. Before heat treatment, steel is made up of ferrite, pearlite, and cementite.
 * Siding:** Siding is the outer covering of a house and is meant to shed water and protect from the effects of weather. Siding may be formed of horizontal or vertical boards, shingles, or sheet materials. Siding can be made of wood, metal, plastic, or masonry (brick).

Write this in the form of a paragraph instead of a list. Ms. Miller

Procedure:
1. Set an equal sample for wood, steel, and siding according to weight, length, width, and height. 2. Set a sample on two tables with a gap in the middle that is also controlled length for each sample. 3. Make sure the amount of the sample is equally separated between the tables. 4. Get a weight of some kind that is the same length of the gap between the tables. 5. Set the weight perfectly on top of the sample. 6. After the weight and the sample are motionless, measure how much the sample bent by measuring the angle at the start of the gap to the lowest point of the parabola. 7. If the sample snaps, simply record the weight used to make that specific sample snap and record it as a snap. 8. Repeat with each sample changing the weight of the weight each time one records all three samples. 9. Record the angle the sample bent to according to the weight of the weight.

Need to be specific with instructions. Ms. Miller
