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.
4.A collect, record, and compare information using tools, including computers, hand lenses, rulers, plastic beakers, magnets, collecting nets, notebooks, and safety goggles or chemical splash goggles, as appropriate; timing devices; 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
5.C demonstrate that things can be done to materials such as cutting, folding, sanding, and melting to change their physical properties; and
5.D combine materials that when put together can do things that they cannot do by themselves such as building a tower or a bridge and justify the selection of those materials based on their physical properties.
6 Force, motion, and energy. The student knows that forces cause change and energy exists in many forms.
6.A investigate the effects on objects 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;
