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;
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
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 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;
