We knew that this type of hands-on learning experience was just the thing that was needed to make boring unit studies not only educational but fun and exciting too! To help you get started with your Project Pack, we have included some of the most frequently asked questions we receive about our Project Packs. What is a Project Pack? A Project Pack contains both the activities and the lesson plans or research guide needed to complete the activities. Imagine your child not only learning about the life cycle of a butterfly, but also creating a cocoon of his or her own. Students don’t just read the story, Blueberry Sal by Robert McCloskey- they enjoy a “blue day” complete with a recipe for blueberry pancakes, making a “blue” collage, and don’t forget painting a “blue” picture! Why is this a better way to learn? How does this help me? Student learning improves when lessons incorporate hands-on projects or crafts. Children learn by doing. Project Packs put learning into their hands! The possibilities are endless when your student begins a lapbook with a Project Pack from In the Hands of a Child. There are no age or skill limits and any topic or subject can be worked into a Project Pack. When you purchase a Project Pack from In the Hands of a Child, all the work is done for you-the parent/teacher, but not for the student. In addition, Project Packs are easy to store, are an instant review tool, a scrapbook, and a ready-made portfolio of all your student’s studies. How do I make a Project Pack? A Project Pack is simply a file folder refolded into a shutter-style book. Open a file folder flat, fold each side into the middle and crease the fold neatly. There you have it! What supplies do I need? You need file folders, paper in different colors and weights*, your student’s favorite coloring tools, tape, glue, scissors, and a stapler. *For a more colorful and appealing Project Pack, it is suggested you print some of the reproducible graphics on colorful, multi-purpose paper. We recommend 24# weight or cardstock. 3|Page I have a Project Pack, NOW what? We hope you are delighted with your new purchase, we’d like to share a few tips with you that we’ve found beneficial to other customers. Here is a brief introduction to our product layout. Table of Contents Guide Core Concepts Graphics Folder Instructions Sample Pictures Each unit starts with a Table of Contents and is followed by a Research Guide. The Research Guide contains all of the lessons needed to complete the activities laid out in a chapter-like format. This format helps to build students’ listening, reading, and comprehension skills. Included in the Research Guide is a Bibliography, which also makes a great resource for finding information for any rabbit trails you may choose to follow during your study. Related books and websites are included in the Research Guide. Next, you will find a list of core concepts to be covered during the study, each of the concepts is represented by a graphic organizer or template. Each graphic organizer or template helps students take bite-sized pieces of information learned in the Research Guide to complete a hands-on activity to help retain that information. If you implement graded assignments in your curriculum, the list of concepts will be essential for you, the parent/teacher, to know what to test the student on. Under each concept you will find the folding instructions for each of the graphic organizers or templates. Each one has a corresponding activity number to make following along easy. Reproducible graphics for the graphic organizers and templates follow. You will want to make a copy of each graphic for each student completing the unit. An instruction sheet for folding file folders and photos of sample lapbooks are included in the back section of each Project Pack. If you and your students are visual learners, you will find the folder instructions and sample photos quite helpful. Project Packs from In the Hands of a Child make great stand-alone unit studies or can easily be added as a supplement to an existing curriculum. When using as a standalone product, we recommend completing 2 - 3 activities per session (30 - 45 minutes). Start by reading through 2 - 3 sections of the Research Guide and then complete the corresponding hands-on activities. The hands-on activities correlate to each section in the Research Guide. 4|Page Vocabulary and Timeline activities do not have to be completed in one day. Vocabulary words can be learned throughout the entire study. We recommend that your student learn a few new vocabulary words each day or learn them as they are written in the Research Guide (all words in bold are vocabulary words). We also recommend Timeline activities be completed a little each day. Choose the time periods you are going to add to your timeline as you read them in the Research Guide. If you are working with young children or a group of children, cut out all of the graphics a day or two before beginning the lapbook and store them in a zip-top bag. It is also helpful to have all materials organized before beginning. All of our early childhood Project Packs include a full supplies list on one of the very first pages! Your student’s completed Project Pack does not have to look like the photo featured at the end of the Pack. The photo is simply a reference to help you understand the folds and the process of putting the file folder together. If you run out of room or things do not fit, add another file folder or an extension! Allow children to take an active role in designing the layout of their project so that it becomes personal for them. The personalizing of their projects aids in the reinforcement of the study. Your students may choose to attach the various activities to their folders as each one is completed or wait until all activities are completed before attaching them to the file folder. If you choose to do the latter, simply store the activities in a zip-top bag, expandable file, or folder until you are ready to assemble them in the file folder.

At first glance, some might just skip over an activity because they feel it is too easy or too difficult for their student. We want you to use all the activities we provide…they are easily adaptable! For example, if you have a PK-3 student the vocabulary activities might be difficult for him or her to complete. Here are some tips to help you adapt the activities that require your student to write: 1. Have your student dictate vocabulary words and their meanings as you write them. 2. Have your child draw a picture instead of writing. 3. You write the word or sentence first so your student can see how it is written (many of our Project Packs also include activities with dotted lines for easy copy work). 4. Practice. Practice. Practice. In the car, on a walk, in the shopping cart! Practice saying the vocabulary words and what they mean. Before you know it, your preschooler will be telling others what those words mean! 5. Contact us. We would be happy to give you ideas for adapting specific units to a grade level. On the other hand, some of the activities may seem too easy for your student. Does your 5th grade student want to learn about butterflies, but the Project Pack seems too easy? Try it anyway; just change things up a bit to suit your student’s grade level and skills. Here are some tips to help you adapt the activities to make them a little more difficult: 1. In addition to writing down vocabulary words and their meanings, ask your student to use the word in a sentence; either verbally or written. 2. Give your student one hour (or reasonable time frame) to research the topic on his or her own either online or at the library. Give your student a set of questions and see what he or she can find without your guidance. 3. Encourage your student to expand on the topic or choose a related subject to learn about. 4. Take a look at some of our preschool units…there is a lot of clipart related to each topic included. Have an older student cut these out and write a story or play about the pictures. 5. Contact us. We would be happy to give you ideas for adapting specific units to a grade level. These are just few ways you can adapt a Project Pack to meet the needs of your student. Let your student be the judge if something is too easy or too difficult…you just might be surprised! 6|Page The Website links we have included in our guides are references we found that contain relevant information.

They are found in the ground or inside rocks. Metals are an important natural resource that people use to make many different products. They have been used since ancient times to make coins, jewelry, machines, tools, and more. Today we use metals to make products that range from aluminum and tin cans to steel skyscrapers Rocks that and space shuttles. Metals are so contain strong and malleable that no other metal are materials compare! Properties of Metal Metals have a unique combination of properties that make them useful for many things. called ores. The Periodic Table Common properties that most metals have include: · · · · · · · · Solid at room temperature (except mercury) Malleable Ductile Reactive Electrical conductors Thermal conductors Shiny appearance Heat resistant The word, "metal" comes from the Greek word "metallon," which means to excavate, extract from the ground, or to mine. Types of Metals The periodic table divides metal elements into many different types of metals. Metals can also be divided into two groups: pure metals and alloys. An element is any substance that contains only one kind of atom and cannot be broken down into simpler elements. The periodic table is a great way to organize all of the elements. Each element on the periodic table has a symbol, which is usually the first two letters of its name (often from the Latin name). On the top of each symbol is the atomic number, which tells you how many protons are in the atom's nucleus. Almost 75% of the elements on the periodic table are classified as metals. There is a stair-step line from Boron (B) to Polonium (Po) in the table. All the elements to the left of the line, except two, can be classified as metals. 18 | P a g e Pure Metals A pure metal is a metal that does not contain any other materials. There are over eighty kinds of pure metals. Pure metals include: · Iron (Fe): Iron is the most common metal found on Earth. It is extracted from hematite, siderite, and other iron ores and is commonly used to make cast iron and steel. The atomic number for iron is 26 and its chemical symbol is Fe, which is short for its Latin name ferrum. Iron also helps to keep our bodies healthy; it is part of hemoglobin. Part of the red blood cells, hemoglobin picks up oxygen from the lungs and carries it in the blood to every cell in the body. If the body does not get enough iron, it can suffer from an illness called anemia. People get iron from foods that they eat such as breads, cereals, pork, rice, and spinach. The first iron used to make tools and weapons came from meteorites that fell to the Earth from space. In early cultures the word for iron meant "metal from the sky." · Aluminum (Al): Aluminum, a silvery-colored metal, is the most common metal in the Earth's crust. It is a light metal that is extracted from bauxite. Aluminum and its alloys are lightweight and do not rust, making it useful for many things, including aircrafts, bicycles, containers, cookware, kitchen foil, and paints. The atomic number of aluminum is 13 and its chemical symbol is Al from the Latin alumen. Prior to the 1800s, pure aluminum was very expensive. In fact, it was valued more than gold or silver. Just one pound of aluminum could cost over $500. In 1889 Charles Hall developed and patented an inexpensive process to obtain pure aluminum, so by the late 1800s the cost of one Metal Ages Metal was discovered by ancient cultures and has changed people's lives ever since. The Metal Ages was a historical period of time when three main metals, copper, bronze, and iron, first came into use. Copper Age (c. 8000-6500 B.C.) The Copper Age was the time period when copper first came into common use. The first metal to be extracted from ore, copper was separated from the rock by a process called annealing. During the Copper Age, copper was used to make decorations, farming implements, and weapons. 19 | P a g e pound of aluminum was under $0.40. · Gold (Au): Gold is a yellow metal that is shiny and does not corrode. Most commonly used to make jewelry, it has been prized as a symbol of wealth since ancient time. Gold is also used in electronics, dentistry, and gold leafing. Pure gold is softer than other metals and is the most ductile. The chemical symbol for gold on the periodic table is Au, from its Latin name aurum. The atomic number for gold is 79. California Gold Rush Throughout history and around the world, the discovery of gold has produced "gold fever" and "gold rushes". When gold was discovered in California in 1849, the population exploded! The state’s motto became “Eureka!” which is Greek for “I’ve found it!” · Silver (Ag): Silver is a soft, shiny metal found and extracted from silver ores. It is the best conductor of electricity and does not corrode or rust. It can, however, tarnish easily. Used since ancient times, silver is used for jewelry, coins, silverware, and electronics. The chemical symbol for silver is Ag, which comes from its Latin name argentum. The atomic number for silver is 47. Prior to 1967, U.S. coins were made of silver. · Copper (Cu): Copper is a reddish-brown metal that is a good electrical conductor and ductile, so it is commonly used for making electrical wires Metal Ages, cont. Bronze Age (c. 3500 B.C.) The Bronze Age was a period of time when bronze was the main metal used. During this time period, people discovered that bronze could be created by combining copper and tin. Bronze was more durable and stronger than copper or tin alone and was commonly used to make containers, statues, tools, and weapons. Iron Age (c. 2000B.C.) During this time in history, ancient cultures discovered how to extract iron from its ore and combine it with carbon to make it better. Iron in its various forms was used for cooking utensils, tools, and weapons. 20 | P a g e and as a building material. The atomic number for copper is 29 and its chemical symbol is Cu, which comes from its Latin name cuprum. Until 1837, U.S. pennies were pure copper. After that, the U.S. government began using less copper per penny as the cost of copper rose. In 1943 a mistake caused some pennies to be 100% pure copper. Today the U.S. penny contains 2.5% copper and the rest is zinc metal. · Magnetic? Unlike many other metals, copper and silver are not magnetic. To determine if a coin is pure silver or copper, place a magnet near it. If the object is attracted to the magnet, it is not pure silver or copper. If the coin is not attracted to the magnet, it is real silver or copper and may be very valuable! Mercury (Hg): Mercury is a liquid metal that is extracted from cinnabar. Named after the planet Mercury, which moves differently from the other planets, the element mercury behaves differently from other metals. The only metal that is liquid at room temperature, it is mainly used in industrial processes, but has been used in thermometers, barometers, lighting, and in the dentistry field. The atomic number of mercury is 80 and its chemical symbol is Hg, which comes from its Latin name hydrargyrum. Mercury can be a very dangerous metal. The liquid can vaporize at room temperature, and when inhaled, causes mercury poisoning. Mercury is also dangerous when it is part of a compound. Dust and vapors from mercury compounds can cause kidney damage, nerve damage, and many severe symptoms throughout the body in people who are exposed to it. · Tin (Sn): Tin is a silvery-white metal. Unlike some metals, tin does not corrode. It is used to plate (coat) other metals to prevent corrosion, especially steel that is used in food-storage cans. Cans that are coated with tin do not corrode and spoil the food. Tin is also used to make toys and as an alloy for other metals. The chemical symbol for tin is Sn, which comes from its Latin name stannum. Tin’s atomic number is 50. How can you tell if a can is made of tin or aluminum? Use a magnet! If the can is attracted to the magnet, it is made of steel coated in tin. If the can is not attracted to the magnet, it is made of aluminum. 21 | P a g e · Lead (Pb): Lead is a soft, blue-white metal that tarnishes to a dull gray. It is highly durable, resistant to corrosion, malleable, ductile, and dense. Lead is used to make solder, fishing weights, sound absorbers, and X-ray shields. Lead compounds are used in paints, insecticides, and storage batteries. The chemical symbol for lead is Pb, which comes from its Latin name plumbum. The atomic number for lead is 82. How plumbers got their name In recent years, it has been discovered that a buildup of lead in the body can A plumber is someone be dangerous. Homes built before who installs and fixes 1978 may have been painted with paint water pipes. Ancient containing lead, and lead may have Romans used lead to been used in the plumbing. It is not make water pipes; the necessary to move out of your house if Latin name for lead is it contains lead, but there are plumbum: plumbers! precautions that homeowners should take. For example, homeowners can purchase a test kit to see if lead is present in their home and then take the necessary precautions to make sure everyone in the house-hold is safe from lead poisoning. Some metals are considered precious metals. Precious metals are more valuable than other metals because there is a limited supply and a great demand. They usually have a high luster and are less reactive than other metals. Precious metals are most often used to make jewelry, artwork, and coins. Precious metals include gold, silver, platinum, and palladium. Alloys Most metallic objects are not pure metals; they are made of alloys, which are stronger or easier to process. Also called metallic compounds, alloys are made by mixing a metal with one or more other elements. Alloys are made to increase a metal's strength, to change the color of a metal, or to make it more resistant to corrosion. There are many types of alloys, including: 22 | P a g e · Brass: Brass is a reddish brown to silvery yellow alloy. Made of copper and zinc, brass is easy to shape, can be polished to a shine, and is resistant to corrosion. It is stronger and harder than copper, but not as strong as steel. It is most commonly used to make decorative items, musical instruments, screws, and pipes. · Bronze: Bronze is an alloy mainly made up of copper, tin, and zinc. It is known for being resistant to corrosion and wear and is commonly used in statues, bells, medals, electrical connectors, ship propellers, and bearings. · Steel: One of the strongest types of alloys is steel. Steel is an alloy made from iron and carbon. It is used to make many different products, including automobiles, building frames, knives, machines, motors, trains, and wires. · Sterling Silver: Sterling silver is an alloy made of silver and copper. It is harder than pure silver and is commonly used to make jewelry. Alloys that are made with iron are called ferrous metals. Ferrous metals are the most commonly used metals. Where in the World is Metal? Different types of metals are found all over the world. Metal ore deposits are valuable and can strengthen the economy of the region in which they are found.

Mining for Metal Finding Metal Before metal ores can be mined, geologists have to find them. Geologists are able to find metal ore reserves by observing, surveying, and sampling. 23 | P a g e 1. Observing: Geologists observe regions by air or land to identify whether metal ore deposits may be present. 2. Surveying: If observations show that metal ore might be present, geologists then survey the area to test the rock properties there. 3. Sampling: Once a metal ore has been identified, geologists use drills to gather samples from the earth. The samples are tested to determine how much metal they contain and whether it would be a good place to mine for the metal. Mining Metal After metal has been found in a region, the process of extracting the metal begins. The extraction process is called mining. There are two main ways of mining for metal ore: · Underground Mining: Metal ore is usually found deep under the Earth's surface. To extract the metal ore, miners have to dig underground and use explosives to create shafts. Next, miners extract the metal ore and transport it up the shafts to the surface. · Open-Pit Mining: Open-pit mining is used to extract metal ores that are located closer to the surface. Also called strip mining, this process is less expensive than underground mining, but can be very damaging to the Earth. In this process, miners make cuts into the Earth and then use machines to extract the metal ore, leaving deep scars in the land. Refining Metal Ore Once a metal ore has been removed from the Earth, it is taken to a mill where it is goes through a process called smelting. This process separates the metal from the rocks, or ores, that contain them. The metal ore is then processed into a powder through a process called leaching. Next, the extracted metal is placed into a furnace and melted at a very high heat. The molten metal is then removed from the furnace and cast into the desired shape. Metal Terminology Common terms associated with metals are: · Cast: form a hard object by putting material into a mold · Extrusion: the shaping of a metal by forcing it through a die · Metallurgy: the study of metals · Smelting: melting or fusing an ore to obtain a metal · Tempering: treating a metal to strengthen it · Welding: joining metals together by heat and the addition of molten filler material 24 | P a g e Recycling Metal Metal is a valuable natural resource, but it takes so long for metal ores to form that we may run out of metals some day. In addition, mining for metal can be damaging to the Earth. The great thing about metal is that it can be melted down and reformed into new objects! It is very important to recycle metals so we do not need to take more from the Earth. Some helpful tips for recycling metals include: · · · · · · · Recycle old batteries Recycle old appliances Recycle used tin or aluminum cans Organize a can drive Purchase used home appliances in good condition instead of new ones Purchase items made of recycled metal Reuse metals by making jewelry or art Metal Crafts You can do your part to recycle metal and make some fun crafts while you are at it!
