TX.112.13.Science, Grade 2.
(2.1) Scientific investigation and reasoning. The student conducts classroom and outdoor investigations following home and school safety procedures. The student is expected to: 2.1 (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.
2.1 (B) Describe the importance of safe practices.
2.1 (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.
(2.10) Organisms and environments. The student knows that organisms resemble their parents and have structures and processes that help them survive within their environments. The student is expected to: 2.10 (A) Observe, record, and compare how the physical characteristics and behaviors of animals help them meet their basic needs such as fins help fish move and balance in the water.
2.10 (B) Observe, record, and compare how the physical characteristics of plants help them meet their basic needs such as stems carry water throughout the plant. Quiz, Flash Cards, Worksheet, Game & Study Guide Plants
2.10 (C) Investigate and record some of the unique stages that insects undergo during their life cycle.
(2.2) Scientific investigation and reasoning. The student develops abilities necessary to do scientific inquiry in classroom and outdoor investigations. The student is expected to: 2.2 (B) Plan and conduct descriptive investigations such as how organisms grow.
2.2 (C) Collect data from observations using simple equipment such as hand lenses, primary balances, thermometers, and non-standard measurement tools.
2.2 (E) Communicate observations and justify explanations using student-generated data from simple descriptive investigations.
2.2 (F) Compare results of investigations with what students and scientists know about the world.
(2.3) 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. The student is expected to: 2.3 (B) Make predictions based on observable patterns.
2.3 (C) Identify what a scientist is and explore what different scientists do.
(2.4) Scientific investigation and reasoning. The student uses age-appropriate tools and models to investigate the natural world. The student is expected to: 2.4 (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.

2.4 (B) Measure and compare organisms and objects using non-standard units that approximate metric units.
(2.5) Matter and energy. The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used. The student is expected to: 2.5 (A) Classify matter by physical properties, including shape, relative mass, relative temperature, texture, flexibility, and whether material is a solid or liquid.
2.5 (B) Compare changes in materials caused by heating and cooling.
(2.6) Force, motion, and energy. The student knows that forces cause change and energy exists in many forms. The student is expected to: 2.6 (B) Observe and identify how magnets are used in everyday life.

2.6 (D) Compare patterns of movement of objects such as sliding, rolling, and spinning.
(2.7) Earth and space. The student knows that the natural world includes earth materials. The student is expected to: 2.7 (A) Observe and describe rocks by size, texture, and color.
2.7 (B) Identify and compare the properties of natural sources of freshwater and saltwater.
2.7 (C) Distinguish between natural and manmade resources.
(2.8) Earth and space. The student knows that there are recognizable patterns in the natural world and among objects in the sky. The student is expected to: 2.8 (A) Measure, record, and graph weather information, including temperature, wind conditions, precipitation, and cloud coverage, in order to identify patterns in the data.

2.8 (D) Observe, describe, and record patterns of objects in the sky, including the appearance of the Moon.
(2.9) Organisms and environments. The student knows that living organisms have basic needs that must be met for them to survive within their environment. The student is expected to: 2.9 (A) Identify the basic needs of plants and animals. Quiz, Flash Cards, Worksheet, Game & Study Guide Animals
2.9 (C) Compare and give examples of the ways living organisms depend on each other and on their environments such as food chains within a garden, park, beach, lake, and wooded area. Quiz, Flash Cards, Worksheet, Game & Study Guide Food Chains
