1 The student conducts classroom and outdoor investigations following home and school safety procedures.
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
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 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;
C collect data from observations using scientific tools;
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, 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
C demonstrate that things can be done to materials such as cutting, folding, sanding, and melting to change their physical properties; and
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.
