- Recognize that water, rocks, soil, and living organisms are found on the earth's surface.
- Understand that air is a mixture of gases that is all around us and that wind is moving air.
- Describe the weather changes from day to day and over the seasons.
- Recognize that the sun supplies heat and light to the earth and is necessary for life.
- Identify some events around us that have repeating patterns, including the seasons of the year, day and night.
- Recognize that animals (including humans) and plants are living things that grow, reproduce, and need food, air, and water.
- Differentiate between living and nonliving things. Group both living and nonliving things according to the characteristics that they share.
- Recognize that plants and animals have life cycles, and that life cycles vary for different living things.
- Describe ways in which many plants and animals closely resemble their parents in observed appearance.
- Recognize that fossils provide us with information about living things that inhabited the earth years ago.
- Recognize that people and other animals interact with the environment through their senses of sight, hearing, touch, smell, and taste.
- Recognize changes in appearance that animals and plants go through as the seasons change.
- Identify the ways in which an organism's habitat provides for its basic needs (plants require air, water, nutrients, and light; animals require food, water, air, and shelter).
- Sort objects by observable properties such as size, shape, color, weight, and texture.
- Identify objects and materials as solid, liquid, or gas. Recognize that solids have a definite shape and that liquids and gases take the shape of their container.
- Describe the various ways that objects can move, such as in a straight line, zigzag, back-and-forth, round and round, fast, and slow.
- Demonstrate that the way to change the motion of an object is to apply a force (give it a push or a pull). The greater the force, the greater the change in the motion of the object.
- Recognize that under some conditions, objects can be balanced.
- Identify and describe characteristics of natural materials (e.g., wood, cotton, fur, wool) and human-made materials (e.g., plastic, Styrofoam).
- Identify and explain some possible uses for natural materials (e.g., wood, cotton, fur, wool) and human-made materials (e.g., plastic, Styrofoam).
- Identify and describe the safe and proper use of tools and materials (e.g., glue, scissors, tape, ruler, paper, toothpicks, straws, spools) to construct simple structures.
- Identify tools and simple machines used for a specific purpose, e.g., ramp, wheel, pulley, lever.
- Describe how human beings use parts of the body as tools (e.g., teeth for cutting, hands for grasping and catching), and compare their use with the ways in which animals use those parts of their bodies.
