(3.10) Organisms and environments. The student knows that organisms undergo similar life processes and have structures that help them survive within their environments. The student is expected to: 3.10 (A) Explore how structures and functions of plants and animals allow them to survive in a particular environment. Quiz, Flash Cards, Worksheet, Game & Study Guide Plants
3.10 (B) Explore that some characteristics of organisms are inherited such as the number of limbs on an animal or flower color and recognize that some behaviors are learned in response to living in a certain environment such as animals using tools to get food.
3.10 (C) Investigate and compare how animals and plants undergo a series of orderly changes in their diverse life cycles such as tomato plants, frogs, and lady bugs. Quiz, Flash Cards, Worksheet, Game & Study Guide Plants
(3.2) Scientific investigation and reasoning. The student uses scientific inquiry methods during laboratory and outdoor investigations. The student is expected to: 3.2 (A) Plan and implement descriptive investigations, including asking and answering questions, making inferences, and selecting and using equipment or technology needed, to solve a specific problem in the natural world.
3.2 (B) Collect data by observing and measuring using the metric system and recognize differences between observed and measured data.
3.2 (C) Construct maps, graphic organizers, simple tables, charts, and bar graphs using tools and current technology to organize, examine, and evaluate measured data.
3.2 (D) Analyze and interpret patterns in data to construct reasonable explanations based on evidence from investigations.
3.2 (F) Communicate valid conclusions supported by data in writing, by drawing pictures, and through verbal discussion.
(3.3) Scientific investigation and reasoning. The student knows that information, critical thinking, scientific problem solving, and the contributions of scientists are used in making decisions. The student is expected to: 3.3 (D) Connect grade-level appropriate science concepts with the history of science, science careers, and contributions of scientists.
(3.4) Scientific investigation and reasoning. The student knows how to use a variety of tools and methods to conduct science inquiry. The student is expected to: 3.4 (A) Collect, record, and analyze information using tools, including microscopes, cameras, computers, hand lenses, metric rulers, Celsius thermometers, wind vanes, rain gauges, pan balances, graduated cylinders, beakers, spring scales, hot plates, meter sticks, compasses, magnets, collecting nets, notebooks, sound recorders, and Sun, Earth, and Moon system models; timing devices, including clocks and stopwatches; and materials to support observation of habitats of organisms such as terrariums and aquariums.

3.4 (B) Use safety equipment as appropriate, including safety goggles and gloves.
(3.5) Matter and energy. The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used. The student is expected to: 3.5 (A) Measure, test, and record physical properties of matter, including temperature, mass, magnetism, and the ability to sink or float. Quiz, Flash Cards, Worksheet, Game & Study Guide Matter
3.5 (B) Describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container. Quiz, Flash Cards, Worksheet, Game & Study Guide Matter
3.5 (C) Predict, observe, and record changes in the state of matter caused by heating or cooling.
3.5 (D) Explore and recognize that a mixture is created when two materials are combined such as gravel and sand and metal and plastic paper clips. Quiz, Flash Cards, Worksheet, Game & Study Guide Matter
(3.6) Force, motion, and energy. The student knows that forces cause change and that energy exists in many forms. The student is expected to: 3.6 (A) Explore different forms of energy, including mechanical, light, sound, and heat/thermal in everyday life.

3.6 (B) Demonstrate and observe how position and motion can be changed by pushing and pulling objects to show work being done such as swings, balls, pulleys, and wagons.
3.6 (C) Observe forces such as magnetism and gravity acting on objects.
(3.7) Earth and space. The student knows that Earth consists of natural resources and its surface is constantly changing. The student is expected to: 3.7 (A) Explore and record how soils are formed by weathering of rock and the decomposition of plant and animal remains.
3.7 (B) Investigate rapid changes in Earth's surface such as volcanic eruptions, earthquakes, and landslides.
3.7 (C) Identify and compare different landforms, including mountains, hills, valleys, and plains.
3.7 (D) Explore the characteristics of natural resources that make them useful in products and materials such as clothing and furniture and how resources may be conserved.
(3.8) Earth and space. The student knows there are recognizable patterns in the natural world and among objects in the sky. The student is expected to: 3.8 (A) Observe, measure, record, and compare day-to-day weather changes in different locations at the same time that include air temperature, wind direction, and precipitation.
