Estimated time to complete: 30 minutes Part A Question Drag the tiles to the boxes to form correct pairs. A fossil can reveal many characteristics and properties of the original species. Match the following characteristics to the fossil of the once-living organism that best demonstrated the characteristic. Tiles was a predator crawled and burrowed walked on two legs was a stationary organism Pairs Part B The chart shows the evolution of animals and plants through several geologic time periods based on fossils that have been found. The time periods in the image are in descending order, with the newest time period at the top. The Cambrian period occurred approximately 500 million years ago, and we are currently in the Quaternary period. Based on the chart, describe the trends that can be observed in animal and plant fossils as they evolved over time. Use evidence from the chart to support your conclusions. 15px Space used (includes formatting): 0 / 15000 Part C The Archaeopteryx lithographica fossil shown in the image is the oldest-known fossil with feathers. The fossil shows evidence that the organism had teeth, wings with fingers and claws, and a backbone that extended into a tail. For these reasons, the Archaeopteryx lithographica is considered a transition fossil, meaning that it links and exhibits traits from two different ancestral groups. Use the chart in part B to identify the two animal groups that this fossil links together. Also explain how transition fossils provide evidence for evolution. 15px Space used (includes formatting): 0 / 15000 Part D The Grand Canyon is made of sedimentary rock that contains fossils up to 1 billion years old. The most commonly found fossils in the Grand Canyon are sea organisms (crinoids, brachiopods, and sponges). However, several upper layers of rock contain terrestrial, or landbased, fossils, such as dragonfly wing impressions and the footprints of scorpions, centipedes, and reptiles. What do these fossils tell us about the evolution of the geosphere at the Grand Canyon? 15px Space used (includes formatting): 0 / 15000 Part E In conclusion, briefly explain and give an example of how fossils provide evidence of evolution within the geosphere and the biosphere. Don’t forget to include transition fossils in your explanation. 15px Space used (includes formatting): 0 / 15000 Unit Activity Unit: Advanced Photography This Course Activity will help you meet these educational goals: • Content Knowledge—You will create an advertisement for a product featuring a model and produce architectural photographs using the appropriate f-stop and shutter speed. • 21st Century Skills—You will apply creativity and innovation, use critical thinking and problem-solving skills, and communicate effectively.

Save & Exit Status: NOT SUBMITTED Task Submit For Review Submit For Score Include selected files Files Comments Print Mineral Identification In this task, you will investigate minerals and classify them based on their properties. Estimated time to complete: 1 hour If you’re using an Edmentum lab kit, get out the bags labeled "Rocks and Minerals" and "Common Materials." The kit materials you'll need from these bags are italicized in the following list. In addition to the kit materials, you'll need to obtain water and a copper penny as the list indicates. If you aren’t using an Edmentum lab kit, please check with your teacher for help. You’ll need these materials: mineral kit (including apatite, calcite, fluorite, graphite, gypsum, magnetite, feldspar/microcline, pyrite, quartz, and talc) porcelain streak plate glass streak plate iron nail scale (with an accuracy of at least 0.1 g) graduated cylinder (100 ml, 250 ml, or any size in between) magnifying hand lens (optional) magnet water copper penny (dated 1982 or older) Part A Luster refers to the way that an object, such as a mineral, reflects light. The luster may be metallic or nonmetallic. A mineral with a metallic luster may look golden or silver. A mineral with a nonmetallic luster may look adamantine (transparent and sparkly like a diamond), pearly, vitreous (glassy), waxy, silky, resinous (like honey), or greasy. Nonmetallic minerals with little or no luster tend to have an earthy, dull look. Examine all the mineral samples in your kit one by one to determine if they have a metallic or a nonmetallic luster. Some minerals may be only partially lustrous. Hold them up to the light and look on all sides for an accurate observation. Classify each mineral as metallic or nonmetallic in the table. 10pt Metallic Luster Nonmetallic Luster Space used (includes formatting): 238 / 15000 Part B The hardness of a mineral is determined by how well it resists scratches. The Mohs scale of hardness is a resource that characterizes the scratch resistance of various minerals based on the ability of a harder material to scratch a softer material. The scale gives a relative comparison between minerals. A rating of 1 means the mineral is soft, and a rating of 10 means the mineral is hard. The object with the highest rating of 10 (diamond) can scratch all other objects on the scale. Here are ratings for some common objects on the Mohs scale of hardness: Object Used to Test Hardness Rating fingernail 2.0 copper penny 3.5 iron nail 4.5 glass 5.5 steel file 6.5 porcelain streak plate 7.0 diamond 10 Test the hardness of your 10 minerals and rank them. Scratch each mineral with some of the objects listed in the table, such as a copper penny or an iron nail. To determine the approximate hardness rating of each mineral, follow these steps: 1. Begin each mineral’s hardness test by scratching it with objects that have a lower Mohs rating, such as your fingernail. 2. Continue scratching with harder and harder objects until you make a scratch in the mineral. (Note: To preserve each mineral’s overall appearance, try to minimize the number of places that you scratch it.) 3. Determine the approximate hardness rating of the mineral. For example, if a mineral is scratched (or flaked) by an iron nail but not by a copper penny, its rating would be approximately 4. 4. Use this scratching method to test all of the minerals, one by one. Then rank them by their approximate hardness score. 5. If you notice that two minerals seem to have the same hardness, you can use them to scratch each other to determine which one is harder. Now, you’ll sequence the minerals according to their hardness, in order from least to greatest. Question Drag each label to the correct location. Using the legend, arrange the minerals that you tested according to their hardness. The hardness will increase from left to right. Mineral Letter quartz Q gypsum Gy calcite C magnetite M graphite Gr feldspar/microcline F apatite Q A Gy C M Gr F A Part C Minerals can be classified based on cleavage or fracture. These two properties refer to the way in which a mineral tends to break. Cleavage is an orderly breakage in well-defined planes. It means that the broken piece of mineral will have flat and smooth sides. Fracture is a random breakage. If a mineral breaks with rough, random, uneven surfaces, it is said to have fractured. Because each of your mineral samples have already been broken from another, larger piece of a mineral, you should be able to tell if it has cleavage or fractures by looking at its sides. Of your 10 minerals, identify three that experienced cleavage. 15px Space used (includes formatting): 0 / 15000 Part D Question Drag each label to the correct location. Geologists study a variety of other characteristics to identify minerals, such as texture, magnetism, streak plate markings, density, and specific gravity. Use the information you have already gathered, in addition to a few other properties of minerals , to identify the seven minerals in the chart below. If you need help using the graduated cylinder or scale, consult the lab instruments and measurements guide. If you do not have access to the seven minerals given, use this resource to complete the chart. quartz gypsum pyrite magnetite graphite fluorite talc Return the minerals to the Edmentum lab kit and wash your hands with soap and warm water.
