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

  • A identify and demonstrate safe practices as described in the Texas Safety Standards during classroom and outdoor investigations, including wearing safety goggles, washing hands, and using materials appropriately;

  • B describe the importance of safe practices; and

  • C 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 The student develops abilities necessary to do scientific inquiry in classroom and outdoor investigations.

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

  • B plan and conduct descriptive investigations such as how organisms grow;

  • C collect data from observations using simple equipment such as hand lenses, primary balances, thermometers, and non-standard measurement tools;

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

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

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

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

  • A identify and explain a problem in his/her own words and propose a task and solution for the problem such as lack of water in a habitat;

  • B make predictions based on observable patterns; and

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

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

  • A collect, record, and compare information using tools, including computers, hand lenses, rulers, primary balances, plastic beakers, magnets, collecting nets, notebooks, and safety goggles; timing devices, including clocks and stopwatches; weather instruments such as thermometers, wind vanes, and rain gauges; and materials to support observations of habitats of organisms such as terrariums and aquariums; and

  • B measure and compare organisms and objects using non-standard units that approximate metric units.

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

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

  • A investigate the effects on an object by increasing or decreasing amounts of light, heat, and sound energy such as how the color of an object appears different in dimmer light or how heat melts butter;

  • B observe and identify how magnets are used in everyday life;

  • C trace the changes in the position of an object over time such as a cup rolling on the floor and a car rolling down a ramp; and

  • D compare patterns of movement of objects such as sliding, rolling, and spinning.

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

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

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

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

  • C explore the processes in the water cycle, including evaporation, condensation, and precipitation, as connected to weather conditions; and

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

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

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