Explore, describe in greater detail, and explain changes in objects and materials using their senses (for example, change in color, shape, texture, form, temperature) during play and collaborative investigations.

Observe and describe the way objects' speed and direction change and explore the effect of their own actions (for example, pushing, pulling, rolling, dropping) on making objects move or stop during play and collaborative investigations.

Make and test predictions about how objects change direction, speed, or the distance they go and, based on their observations, explain why objects start, stop, or change direction or speed during play and collaborative investigations.

Demonstrate awareness, with adult support, that things (living and nonliving) need sources of energy to function.

Demonstrate awareness, with adult support, of the different sources of energy that things (living and nonliving) need and describe the changes they observe as a result of these sources of energy.

Identify and describe characteristics of a variety of animals and plants, including appearance (inside and outside) and behavior, and demonstrate an emerging ability to categorize them.

Identify and describe characteristics of a greater variety of animals and plants and demonstrate an increased ability to categorize them.

Indicate emerging knowledge of bodily processes (for example, eating, sleeping, breathing, walking) in humans and other animals.

Indicate greater knowledge of bodily processes (for example, eating, sleeping, breathing, walking) in humans and other animals through more detailed observations and descriptions.

Expect animate objects (people and animals) to self-initiate movement and to have different insides and biological processes that make them behave differently from inanimate objects.

Indicate knowledge of the difference between living and nonliving things and recognize that only living things (people, animals, plants) undergo biological changes such as growth, illness, healing, and dying.

Name and describe similarities and differences they observe between grown animals, including humans, and their young ones.

Express their expectation that young animals and plants will reflect similar characteristics to grown animals and plants of the same kind.

Identify the habitats of people and familiar animals and plants and communicate their understanding that living things have different habitats.

Recognize that living things have different habitats suited to their unique needs.

Observe and explore growth and changes in humans, animals, and plants and communicate an understanding that living things change over time in size and other capacities as they grow and age.

Observe and explore growth in humans, animals, and plants and communicate an increased understanding that living things change as they grow and age. Describe transformations related to an individual's life cycle (for example, birth, growth, reproduction, death).

Recognize that animals and plants require care and show an emerging understanding that feeding and watering support the growth and survival of humans, animals, and plants.

Describe the needs of humans, animals, and plants for growth and survival (for example, food, water, sleep, sunshine, shelter).

Investigate and describe the characteristics (for example, size, weight, shape, color, texture) of earth materials such as sand, rocks, soil, water, and air.

Investigate and describe the characteristics of earth materials and compare and contrast materials based on their different features (for example, size, weight, shape, color, texture).
