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

  • A demonstrate safe practices and the use of safety equipment as described in the Texas Safety Standards during classroom and outdoor investigations; and

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

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

3 The student uses critical thinking and scientific problem solving to make informed 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 services and product claims found in advertisements and labels such as for toys, food, and sunscreen;

  • C represent the natural world using models such as rivers, stream tables, or fossils and identify their limitations, including accuracy and size; 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, materials, equipment, and models to conduct science inquiry.

  • A collect, record, and analyze information using tools, including calculators, microscopes, cameras, computers, hand lenses, metric rulers, Celsius thermometers, mirrors, spring scales, pan balances, triple beam balances, graduated cylinders, beakers, hot plates, meter sticks, compasses, magnets, collecting nets, and notebooks; 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 energy exists in many forms and can be observed in cycles, patterns, and systems.

7 The students know that Earth consists of useful resources and its surface is constantly changing.

8 The student knows that there are recognizable patterns in the natural world and among the Sun, Earth, and Moon system.

9 The student knows and understands that living organisms within an ecosystem interact with one another and with their environment.

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