Grade Three 2011-2012 Science Course of Study Observations of the Environment Earth and Space Science TOPIC: Earth’s Resources CONTENT STATEMENT Earth's nonliving resources have specific properties. CONCEPTS VOCABUALRY Soil is composed of pieces of rock, organic material, water and air and has characteristics that can be measured and observed. Rocks have unique characteristics that allow them to be sorted and classified. Rocks form in different ways. Air and water are nonliving resources. Characteristics Minerals Properties Field Guide Coarse Grained Fine Grained Luster Composition Organic Sediment Sedimentary Metamorphic Igneous PERFORMANCE SKILLS: Compare properties of rocks. Observe rocks and describe similarities and differences. Sort rocks according to the different properties. Describe the process that forms the three major groups of rocks. Discover that how a rock was formed affects some of its properties. Recognize that soil can have different texture, composition, or color depending on the environment in which it formed. Design an investigation to test specific properties of different types of soil, such as ability to absorb (hold) water, matching/designating soil color, the ability for water to pass through the soil, the filtering properties of soil.

CONCEPTS VOCABULARY Many of Earth’s resources can be used for the energy they contain. Renewable energy is an energy resource, such as wind, water or solar energy that is replenished within a short amount of time by natural processes. Nonrenewable energy is an energy resource, such as coal or oil that is a finite energy source that cannot be replenished in a short amount of time. Renewable Nonrenewable Energy Resources PERFORMANCE SKILLS: List the differences between renewable and nonrenewable energy. Be able to provide examples of each. -2- Grade Three 2011-2012 Science Course of Study Observations of the Environment Earth and Space Science TOPIC: Earth’s Resources CONTENT STATEMENT Some of Earth’s resources are limited. CONCEPTS VOCABULARY Some of Earth’s resources become limited due to overuse and/or contamination. Reducing resource use, decreasing waste and/or pollution, recycling and reusing can help conserve these resources. Conservation Reducing Reusing Recycling Contamination Pollution PERFORMANCE SKILLS: Research different types of recycling (paper, plastics, metals, glass) and make a table to document methods, effectiveness, recycling rates, benefits, and/or problems. Recognize that some of Earth’s resources are limited and need to be conserved. -3- Grade Three 2011-2012 Science Course of Study Observations of the Environment Life Science TOPIC: Behavior, Growth and Changes CONTENT STATEMENT Offspring resemble their parents and each other. CONCEPTS VOCABULARY Individual organisms inherit many traits from their parents indicating a reliable way to transfer information from one generation to the next. Some behavioral traits are learned through interactions with the environment and are not inherited. Organism Generation Traits Environment Inherited Physical Adaptations/Characteristics Hibernation Migration Mimicry Behavioral Adaptation/Characteristics PERFORMANCE SKILLS: Conduct a real-time observational study of a familial grouping of organisms. Use web cams to view animals in their natural habitat or simulated environments to observe and record physical characteristics of the animals as well as behavioral traits that are taught from parent to offspring. (Example: Falcon cams are used by the Ohio Department of Natural Resources and can be used for this study. http://ohiodnr.com/wildlife/dow/falcons/Default.aspx ) Identify physical characteristics using pictures. -4- Grade Three 2011-2012 Science Course of Study Observations of the Environment Life Science TOPIC: Behavior, Growth and Changes CONTENT STATEMENT Individuals of the same kind differ in their traits and sometimes the differences give individuals an advantage in surviving and reproducing. CONCEPTS VOCABULARY Animals have physical features that are associated with the environments where they live. Animals have certain physical or behavioral characteristics that improve their chances of surviving in particular environments. Individuals of the same kind have different characteristics that they have inherited. Sometimes these different characteristics give individuals an advantage in surviving and reproducing. Organism Generation Traits Environment Inherited Physical Adaptations/Characteristics Hibernation Migration Mimicry Behavioral Adaptation/Characteristics PERFORMANCE SKILLS: Identify physical characteristics that are inherited but serve a different function for each animal. (example: bird beaks) -5- Grade Three 2011-2012 Science Course of Study Observations of the Environment Life Science TOPIC: Interactions within Habitats CONTENT STATEMENT Living things cause changes on Earth. CONCEPTS VOCABULARY Living things function and interact with their physical environments. Living things cause changes in the environments where they live; the changes can be very noticeable or slightly noticeable, fast or slow. Erosion Environment Ecosystem Biome Climate PERFORMANCE SKILLS: Recognize scientifically accurate facts in stories about environmental change caused by living things. Develop a chart, table, graph to record changes in environmental factors (both living and nonliving) using data obtained from classroom investigations, or real world examples. -6- Grade Three 2011-2012 Science Course of Study Observations of the Environment Life Science TOPIC: Interactions within Habitats CONTENT STATEMENT Some kinds of individuals that once lived on Earth have completely disappeared, although they were something like others that are alive today. CONCEPTS VOCABULARY Living things that once lived on Earth no longer exist; their basic needs were no longer met. Extinct Paleontologist Fossils PERFORMANCE SKILLS: Name an organism that was once abundant that is now extinct. -7-
