Este documento presenta un sendero de interpretación sobre el ciclo de vida en la naturaleza. Explica que el suelo permite el desarrollo de plantas y animales al proveer nutrientes y soporte, y cómo las plantas ayudan a prevenir la erosión del suelo. También describe cómo los organismos vivos en el suelo descomponen las hojas caÃdas, reciclando sus nutrientes y manteniendo el ciclo.

This document summarizes a burn attempt using Nero to write an image file to DVD media. The burn was started using Disc-at-Once mode on DVD media but was aborted by the user after the recorder preparation and setup were completed. The log provides details on the software and hardware configuration, the image file being written, and playbacks the activities up until the user aborted the burn process.

This document contains instructions for an experiment to measure the time it takes for a varying number of students to complete a task of standing, clapping, and sitting. Students will take turns performing the task until all have participated, and the time to complete each round will be recorded. The number of students is the independent variable and time is the dependent variable. Data for groups of 3 to 24 students will be plotted on a graph and the best fit line drawn to analyze the correlation between more students and longer completion times.Budget project

This document provides instructions for creating a realistic monthly budget. It explains that a budget accounts for income versus expenses, with the goal of expenses being less than income. Common expenses are listed like housing, utilities, transportation, food, and savings, which should be at least 5% of income. Students will be assigned an occupation with a set income and must choose housing, a car, and estimate other expenses to track in a monthly budget worksheet. If expenses exceed income or savings is less than 5%, spending habits must be adjusted.Scale drawing table

This document provides instructions for creating a scale drawing of a piece of furniture. It notes that measurements should be provided in either boxes or inches, not both. As an example, a grey shelf that is 3 feet by 1 foot in real life would be drawn as either 3 boxes by 1 box or 0.75 inches by 0.25 inches on the scale drawing, since the scale factor is that 1 foot equals 1/4 inch or one box.Linear equation graphic

A linear equation is represented by y = mx + b, where m is the coefficient that determines the steepness of the graph line, b is the y-intercept or the point at which the line crosses the y-axis, and x and y are coordinate pairs that each represent a single point on the line.

This document provides instructions for a scale drawing project of a classroom floor plan. Students are asked to measure a classroom, determine an appropriate scale to fit the room on a piece of graph paper, and draw the outline of the room along with major furniture items using the scale. Students must include a scale bar, title, and colors to make the floor plan realistic. The project aims to provide floor plans of classrooms to facilitate school renovations.Scale drawing do nows

This document provides directions for creating a personal lifeline. Students must include their birth and at least 3 events that occurred before they were born, with each event listing the date as a fraction of years before or after the student's birth (assigned as 0). Events should have the month and year, the student's age at the event, and a brief description. Sample events include parents meeting, siblings being born, first teeth, words, bike riding, moves, vacations, or historical events. The lifeline may include one break and some photos.Polygons and quadrilaterals

Vertical angles are angles that are opposite each other when two lines intersect. Corresponding angles are angles that are in the same relative position to the point of intersection but on opposite sides of the intersecting lines. Alternate exterior angles are nonadjacent angles outside of the intersecting lines formed by a transversal crossing two parallel lines. Alternate interior angles are nonadjacent angles inside of the intersecting lines formed by a transversal crossing two parallel lines.Lesson 3 line and angle relationships

This document discusses different types of lines and their relationships. It defines parallel lines as two lines that lie in the same plane and do not intersect, intersecting lines as lines that cross paths at one point, and skew lines as lines that do not lie in the same plane and neither intersect nor are parallel. The document also notes that two points are needed to form a line and that two straight lines cannot intersect at more than one point.Angle relationships

The document defines basic geometry terms including point, line, plane, ray, line segment, and angle. A point is represented by a dot at a location without size. A line extends in two opposite directions and is named by two points. A plane extends forever like a tabletop. A ray has one endpoint and extends forever in one direction, while a line segment connects two endpoints on a line.Sample questions 2013
