1 The student conducts classroom and outdoor investigations following school and home safety procedures and environmentally appropriate practices.

  • A demonstrate safe practices as described in the Texas Safety Standards during classroom and outdoor investigations, including observing a schoolyard habitat; and

  • B make informed choices in the use and conservation of natural resources by recycling or reusing materials such as paper, aluminum cans, and plastics.

2 The student uses scientific inquiry methods during laboratory and outdoor investigations.

3 The student knows that information, critical thinking, scientific problem solving, and the contributions of scientists are used in making decisions.

  • A in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student;

  • B draw inferences and evaluate accuracy of product claims found in advertisements and labels such as for toys and food;

  • C represent the natural world using models such as volcanoes or Sun, Earth, and Moon system and identify their limitations, including size, properties, and materials; and

  • D connect grade-level appropriate science concepts with the history of science, science careers, and contributions of scientists.

4 The student knows how to use a variety of tools and methods to conduct science inquiry.

  • 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; and

  • B use safety equipment as appropriate, including safety goggles and gloves.

5 The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used.

6 The student knows that forces cause change and that energy exists in many forms.

7 The student knows that Earth consists of natural resources and its surface is constantly changing.

8 The student knows there are recognizable patterns in the natural world and among objects in the sky.

  • 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;

  • B describe and illustrate the Sun as a star composed of gases that provides light and heat energy for the water cycle;

  • C construct models that demonstrate the relationship of the Sun, Earth, and Moon, including orbits and positions; and

  • D identify the planets in Earth's solar system and their position in relation to the Sun.

9 The student knows that organisms have characteristics that help them survive and can describe patterns, cycles, systems, and relationships within the environments.

10 The student knows that organisms undergo similar life processes and have structures that help them survive within their environments.
