## Earth and Space Science

### S2E1: Star Size and Brightness

Obtain, evaluate, and communicate information about stars having different sizes and brightness.

- **S2E1.a**: Ask questions to describe the physical attributes (size and brightness) of stars.
- **S2E1.b**: Construct an argument to support the claim that although the sun appears to be the brightest and largest star, it is actually medium in size and brightness.

### S2E2: Sun and Moon Patterns

Obtain, evaluate, and communicate information to develop an understanding of the patterns of the sun and the moon and the sun's effect on Earth.

- **S2E2.a**: Plan and carry out an investigation to determine the effect of the position of the sun in relation to a fixed object on Earth at various times of the day.
- **S2E2.b**: Design and build a structure that demonstrates how shadows change throughout the day.
- **S2E2.c**: Represent data in tables and/or graphs of the length of the day and night to recognize the change in seasons.
- **S2E2.d**: Use data from personal observations to describe, illustrate, and predict how the appearance of the moon changes over time in a pattern.

### S2E3: Environmental Changes Overview

Obtain, evaluate, and communicate information about how weather, plants, animals, and humans cause changes to the environment.

- **S2E3.a**: Ask questions to obtain information about major changes to the environment in your community.
- **S2E3.b**: Construct an explanation of the causes and effects of a change to the environment in your community.

## Physical Science

### S2P1: Properties and Changes of Matter

Obtain, evaluate, and communicate information about the properties of matter and changes that occur in objects.

- **S2P1.a**: Ask questions to describe and classify different objects according to their physical properties.
- **S2P1.b**: Construct an explanation for how structures made from small pieces (linking cubes, building blocks) can be disassembled and then rearranged to make new and different structures.
- **S2P1.c**: Provide evidence from observations to construct an explanation that some changes in matter caused by heating or cooling can be reversed and some changes are irreversible.

### S2P2: Forces and Object Motion

Obtain, evaluate, and communicate information to explain the effect of a force (a push or a pull) in the movement of an object (changes in speed and direction).

- **S2P2.a**: Plan and carry out an investigation to demonstrate how pushing and pulling on an object affects the motion of the object.
- **S2P2.b**: Design a device to change the speed or direction of an object.
- **S2P2.c**: Record and analyze data to decide if a design solution works as intended to change the speed or direction of an object with a force (a push or a pull).

## Life Science

### S2L1: Life Cycles of Organisms

Obtain, evaluate, and communicate information about the life cycles of different living organisms.

- **S2L1.a**: Ask questions to determine the sequence of the life cycle of common animals in your area: a mammal such as a cat, dog or classroom pet, a bird such as a chicken, an amphibian such as a frog, and an insect such as a butterfly.
- **S2L1.b**: Plan and carry out an investigation of the life cycle of a plant by growing a plant from a seed and by recording changes over a period of time.
- **S2L1.c**: Construct an explanation of an animal's role in dispersing seeds or in the pollination of plants.
- **S2L1.d**: Develop models to illustrate the unique and diverse life cycles of organisms other than humans.
