Actions

1 Scientific investigation and reasoning. The student conducts classroom and outdoor investigations following home and school safety procedures.

  • 1.A identify, describe, and demonstrate safe practices as outlined in Texas Education Agency-approved safety standards during classroom and outdoor investigations, including wearing safety goggles or chemical splash goggles, as appropriate, washing hands, and using materials appropriately; and

  • 1.B identify and demonstrate how to use, conserve, and dispose of natural resources and materials such as conserving water and reuse or recycling of paper, plastic, and metal.

2 Scientific investigation and reasoning. The student develops abilities necessary to do scientific inquiry in classroom and outdoor investigations.

  • 2.A ask questions about organisms, objects, and events during observations and investigations;

  • 2.B plan and conduct descriptive investigations;

  • 2.C collect data from observations using scientific tools;

  • 2.D record and organize data using pictures, numbers, and words;

  • 2.E communicate observations and justify explanations using student-generated data from simple descriptive investigations; and

  • 2.F compare results of investigations with what students and scientists know about the world.

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

  • 3.A identify and explain a problem and propose a task and solution for the problem;

  • 3.B make predictions based on observable patterns; and

  • 3.C identify what a scientist is and explore what different scientists do.

4 Scientific investigation and reasoning. The student uses age-appropriate tools and models to investigate the natural world.

5 Matter and energy. The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used.

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

7 Earth and space. The student knows that the natural world includes earth materials.

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

  • 8.A measure, record, and graph weather information, including temperature, wind conditions, precipitation, and cloud coverage, in order to identify patterns in the data;

  • 8.B identify the importance of weather and seasonal information to make choices in clothing, activities, and transportation; and

  • 8.C observe, describe, and record patterns of objects in the sky, including the appearance of the Moon.

9 Organisms and environments. The student knows that living organisms have basic needs that must be met for them to survive within their environment.

10 Organisms and environments. The student knows that organisms resemble their parents and have structures and processes that help them survive within their environments.
