Earth Science
S2E1. Students will understand that stars have different sizes, brightness, and patterns.
a. Describe the physical attributes of stars—size, brightness, and patterns.
S2E2. Students will investigate the position of sun and moon to show patterns throughout the year.
a. Investigate the position of the sun in relation to a fixed object on earth at various times of the day.
b. Determine how the shadows change through the day by making a shadow stick or using a sundial.
c. Relate the length of the day and night to the change in seasons (for example: Days are longer than the night in the summer.).
d. Use observations and charts to record the shape of the moon for a period of time.
S2E3. Students will observe and record changes in their surroundings and infer the causes of the changes.
a. Recognize effects that occur in a specific area caused by weather, plants, animals, and/or people.
Physical Science
S2P1. Students will investigate the properties of matter and changes that occur in objects.
a. Identify the three common states of matter as solid, liquid, or gas.
b. Investigate changes in objects by tearing, dissolving, melting, squeezing, etc.
S2P2. Students will identify sources of energy and how the energy is used.
a. Identify sources of light energy, heat energy, and energy of motion.
b. Describe how light, heat, and motion energy are used.
S2P3. Students will demonstrate changes in speed and direction using pushes and pulls.
a. Demonstrate how pushing and pulling an object affects the motion of the object.
b. Demonstrate the effects of changes of speed on an object.
Life Science
Teacher note: Instruct students not to touch wild plants and animals when they observe them. Always wash hands after handling any plants or animals. Caution students not to eat wild plants they find.
S2L1. Students will investigate the life cycles of different living organisms.
a. Determine the sequence of the life cycle of common animals in your area: a mammal such as a cat or dog or classroom pet, a bird such as a chicken, an amphibian such as a frog, and an insect such as a butterfly.
b. Relate seasonal changes to observations of how a tree changes throughout a school year.
c. Investigate the life cycle of a plant by growing a plant from a seed and by recording changes over a period of time.
d. Identify fungi (mushroom) as living organisms.
