b Observe rocks using a magnifying glass and draw shapes and colors of the minerals.
c Sort rocks by appearance according to the three basic types: sedimentary, igneous and metamorphic (e.g., sedimentary–rounded-appearing mineral and rock particles that are cemented together, often in layers; igneous–with or without observable crystals that are not in layers or with or without air holes or glasslike; metamorphic –crystals/minerals, often in layers).
c Research locations where fossils are found in Utah and construct a simple fossil map.
2 Explain how fossils can be used to make inferences about past life, climate, geology, and environments.
a Explain why fossils are usually found in sedimentary rock.
b Based on the fossils found in various locations, infer how Utah environments have changed over time (e.g., trilobite fossils indicate that Millard County was once covered by a large shallow ocean; dinosaur fossils and coal indicate that Emery and Uintah County were once tropical and swampy).
c Research information on two scientific explanations for the extinction of dinosaurs and other prehistoric organisms.
d Formulate questions that can be answered using information gathered on the extinction of dinosaurs.
5 Students will understand the physical characteristics of Utah's wetlands, forests, and deserts and identify common organisms for each environment.
1 Describe the physical characteristics of Utah's wetlands, forests, and deserts.
a Compare the physical characteristics (e.g., precipitation, temperature, and surface terrain) of Utah's wetlands, forests, and deserts.
b Describe Utah's wetlands (e.g., river, lake, stream, and marsh areas where water is a major feature of the environment) forests (e.g., oak, pine, aspen, juniper areas where trees are a major feature of the environment), and deserts (e.g., areas where the lack of water provided an environment where plants needing little water are a major feature of the environment).
c Locate examples of areas that have characteristics of wetlands, forests, or deserts in Utah.
d Based upon information gathered, classify areas of Utah that are generally identified as wetlands, forests, or deserts.
e Create models of wetlands, forests, and deserts.
2 Describe the common plants and animals found in Utah environments and how these organisms have adapted to the environment in which they live.
a Identify common plants and animals that inhabit Utah's forests, wetlands, and deserts.
b Cite examples of physical features that allow particular plants and animals to live in specific environments (e.g., duck has webbed feet, cactus has waxy coating).
c Describe some of the interactions between animals and plants of a given environment (e.g., woodpecker eats insects that live on trees of a forest, brine shrimp of the Great Salt Lake eat algae and birds feed on brine shrimp).
