Día De Los Muertos K-12 Educator’S Guide
Día de los Muertos K-12 Educator’s Guide Produced by the University of New Mexico Latin American & Iberian Institute Latin American & Iberian Institute Because of the geographic location and unique cultural history of New Mexico, the University of New Mexico (UNM) has emphasized Latin American Studies since the early 1930s. In 1979, the Latin American & Iberian Institute (LAII) was founded to coordinate Latin American programs on campus. Designated a National Resource Center (NRC) by the U.S. Department of Education, the LAII offers academic degrees, supports research, provides development opportunities for faculty, and coordinates an outreach program that reaches diverse constituents. In addition to the Latin American Studies (LAS) degrees offered, the LAII supports Latin American studies in departments and professional schools across campus by awarding stu- dent fellowships and providing funds for faculty and curriculum development. The LAII’s mission is to create a stimulating environment for the production and dissemination of knowl- edge of Latin America and Iberia at UNM. We believe our goals are best pursued by efforts to build upon the insights of more than one academic discipline. In this respect, we offer interdisciplinary resources as part of our effort to work closely with the K-12 community to help integrate Latin American content mate- rials into New Mexico classrooms across grade levels and subject areas. We’re always glad to work with teachers to develop resources specific to their classrooms and students. To discuss this option, or for more comprehensive information about the LAII and its K-12 resources, contact: University of New Mexico Latin American & Iberian Institute 801 Yale Boulevard NE MSC02 1690 1 University of New Mexico Albuquerque, NM 87131 Phone: (505) 277-2961 Fax: (505) 277-5989 Email: [email protected] Web: http://laii.unm.edu *Images: Cover photograph of calavera provided courtesy of Reid Rosenberg, reprinted here under CC ©. -

PEER-REVIEWED REVIEW ARTICLE bioresources.com Understanding the Effect of Machine Technology and Cellulosic Fibers on Tissue Properties – A Review Tiago de Assis,a Lee W. Reisinger,b Lokendra Pal,a Joel Pawlak,a Hasan Jameel,a and Ronalds W. Gonzalez a,* Hygiene tissue paper properties are a function of fiber type, chemical additives, and machine technology. This review presents a comprehensive and systematic discussion about the effects of the type of fiber and machine technology on tissue properties. Advanced technologies, such as through-air drying, produce tissue with high bulk, softness, and absorbency. Conventional technologies, where wet pressing is used to partially dewater the paper web, produces tissue with higher density, lower absorbency, and softness. Different fiber types coming from various pulping and recycling processes are used for tissue manufacturing. Softwoods are mainly used as a source of reinforcement, while hardwoods provide softness and a velvet type surface feel. Non- wood biomass may have properties similar to hardwoods and/or softwoods, depending on the species. Mechanical pulps having stiffer fibers result in bulkier papers. Chemical pulps have flexible fibers resulting in better bonding ability and softness. Virgin fibers are more flexible and produce stronger and softer tissue. Recycled fibers are stiffer with lower bonding ability, yielding products that are weaker and less soft. Mild mechanical refining is used to improve limitations found in recycled fibers and to develop properties in virgin fibers. -
Making Paper from Trees
Making Paper from Trees Forest Service U.S. Department of Agriculture FS-2 MAKING PAPER FROM TREES Paper has been a key factor in the progress of civilization, especially during the past 100 years. Paper is indispensable in our daily life for many purposes. It conveys a fantastic variety and volume of messages and information of all kinds via its use in printing and writing-personal and business letters, newspapers, pamphlets, posters, magazines, mail order catalogs, telephone directories, comic books, school books, novels, etc. It is difficult to imagine the modern world without paper. Paper is used to wrap packages. It is also used to make containers for shipping goods ranging from food and drugs to clothing and machinery. We use it as wrappers or containers for milk, ice cream, bread, butter, meat, fruits, cereals, vegetables, potato chips, and candy; to carry our food and department store purchases home in; for paper towels, cellophane, paper handkerchiefs and sanitary tissues; for our notebooks, coloring books, blotting paper, memo pads, holiday greeting and other “special occasion’’ cards, playing cards, library index cards; for the toy hats, crepe paper decorations, paper napkins, paper cups, plates, spoons, and forks for our parties. Paper is used in building our homes and schools-in the form of roofing paper, and as paperboard- heavy, compressed product made from wood pulp-which is used for walls and partitions, and in such products as furniture. Paper is also used in linerboard, “cardboard,” and similar containers. Wood pulp is the principal fibrous raw material from which paper is made, and over half of the wood cut in this country winds up in some form of paper products. -

CHANGES IN PRINT PAPER DURING THE 19TH CENTURY AJ Valente, ([email protected]), President, Paper Antiquities When the first paper mill in America, the Rittenhouse Mill, was built, Western European nations and city-states had been making paper from linen rags for nearly five hundred years. In a poem written about the Rittenhouse Mill in 1696 by John Holme it is said, “Kind friend, when they old shift is rent, Let it to the paper mill be sent.” Today we look back and can’t remember a time when paper wasn’t made from wood-pulp. Seems that somewhere along the way everything changed, and in that respect the 19th Century holds a unique place in history. The basic kinds of paper made during the 1800s were rag, straw, manila, and wood pulp. -
Paper Towel Strength and Absorbency
Paper Towel Strength and Absorbency Summary Think about the last time you spilled a drink. How did you clean it up? Most likely you grabbed the nearest roll of paper towels. Why didn’t you use a roll of toilet paper or why didn’t you grab a wad of notebook or computer paper? What is it about a paper towel that makes it so useful to clean up spilled liquids? It has to do with how the paper towels are made. Paper towels are made from the same types of plant fibers that other types of paper are made from. The difference between paper towels and other types of paper comes when the paper fibers are mixed with a special type of resin to make them strong when they are wet. That’s why paper towels don’t tear as easily as notebook paper or tissue paper when they are wet. Once the sheets are made they have shapes pressed into them to make them look quilted. These shapes form air pockets to attract water. That is why paper towels are so absorbent. Different brands of paper towels have different methods for manufacturing their paper towels. In this activity you will get to test different brands of paper towels for their strength and absorbency. In this activity we will: 1. Observe what qualities about paper towels give them the best strength and ability to absorb water. 2. Test four different brands of paper towels to see which is the strongest and most absorbent. Materials - four or more different brands of paper towels - a jar of pennies - bowl of water - teaspoon - eye dropper or turkey baster - two assistants - record sheet and pencil (see below) Preparation 1. -
Día De Los Muertos Teacher Workshop
Día de los Muertos Teacher Workshop Fall 2012 K-12 Curriculum Resource Guide developed and presented by the Stone Center for Latin American Studies, Tulane University THE DAY OF THE DEAD by Margarita Vargas-Betancourt I. Introduction • Mexicans believe that during the day of the dead, the dead come back to visit their beloved who still live. • It is a time of great festivity and reunion, rather than mournful lamentation. II. The roots A. European roots • Catholic celebration of All Saints • Medieval dances of death: staging of devils and angels fighting for the souls of the dead. Death is represented as a fearful lady (sandglass, scythe, cart) B. Pre-Columbian roots • Cyclic time: dry season/ rainy season, death/life • Agricultural celebrations: day of the dead coincides with the beginning of harvest • Aztec celebrations to the dead III. The offering: la ofrenda • Purpose: 1. To honor and welcome them. 2. To make them know that they have not been forgotten in death. 3. To remind them of the sweetness of life that they once enjoyed. • Elements: 1. It is done on a table that has a colorful tablecloth (purple, orange, white) 2. Photographs of the deceased are placed in a central location 3. Copan incense 4. Cempasuchil (yellow marigold flowers) and terciopelo (a purplish-dark pink flower that looks like velvet). 5. Water: it is believed that the souls arrive thirsty from their long trip, and that they drink the water from the glass that we offered them. Thus, it is believed that as the night progresses the level of water in a glass placed on the ofrenda sinks too quickly to be by evaporation. -
Corrugated Cardboard Magazines
Most of us use a paper product every day. That's because paper products make up about 71 million tons (or 29 percent) of the municipal waste stream, according to the Environmental Protection Agency (EPA). The good news is that more and more Americans are recycling paper. In fact, upwards of 63 percent (45 million tons) is recycled annually. When you break that number down by population, roughly 334 pounds of paper is recycled for every person in the United States. Corrugated Cardboard Currently, about 70 percent of cardboard-boxes shipped commercially are recovered for recycling. Many of the boxes are themselves made of recycled materials or lumber industry byproducts like sawdust and wood chips. When recycled, cardboard is used to make chipboard like cereal boxes, paperboard, paper towels, tissues and printing or writing paper. It's also made into more corrugated cardboard. How It's Recycled: 1. The cardboard is re-pulped and the fibers are separated and bleached. This is a chemical process involving hydrogen peroxide, sodium silicate, and sodium hydroxide. 2. The fibers are screened and cleaned to eliminate contaminants. 3. The fibers are washed to remove leftover ink. 4. Fibers are pressed and rolled into paper. 5. he rolls of paper are then converted into boxes or made into new products. Magazines Magazines are made from paper that's been buffed and coated to achieve a glossy appearance. Next, the paper is covered with a white clay that makes color photographs look more brilliant. The shiny appearance does not contaminate the paper at all. About 45 percent of sub-content-3 are being recycled today. -
