Third Grade Standards

S3E1. Students will investigate the physical attributes of rocks and soils.

a. Explain the difference between a rock and a mineral.

b. Recognize the physical attributes of rocks and minerals using observation (shape, color, texture), measurement, and simple tests (hardness).

c. Use observation to compare the similarities and differences of texture, particle size, and color in top soils (such as clay, loam or potting soil, and sand).

d. Determine how water and wind can change rocks and soil over time using observation and research.

S3E2. Students will investigate fossils as evidence of organisms that lived long ago.

a. Investigate fossils by observing authentic fossils or models of fossils or view information resources about fossils as evidence of organisms that lived long ago.

b. Describe how a fossil is formed.

S3P1. Students will investigate how heat is produced and the effects of heating and cooling, and will understand a change in temperature indicates a change in heat.

a. Categorize ways to produce heat energy such as burning, rubbing (friction), and mixing one thing with another.

b. Investigate how insulation affects heating and cooling.

c. Investigate the transfer of heat energy from the sun to various materials.

d. Use thermometers to measure the changes in temperatures of water samples (hot, warm, cold) over time.

S3P2. Students will investigate magnets and how they affect other magnets and common objects.

a. Investigate to find common objects that are attracted to magnets.

b. Investigate how magnets attract and repel each other.

S3L1. Students will investigate the habitats of different organisms and the dependence of organisms on their habitat.

a. Differentiate between habitats of Georgia (mountains, marsh/swamp, coast, Piedmont, Atlantic Ocean) and the organisms that live there.

b. Identify features of green plants that allow them to live and thrive in different regions of Georgia.

c. Identify features of animals that allow them to live and thrive in different regions of Georgia.

d. Explain what will happen to an organism if the habitat is changed.

S3L2. Students will recognize the effects of pollution and humans on the environment.

a. Explain the effects of pollution (such as littering) to the habitats of plants and animals.

b. Identify ways to protect the environment.

• Conservation of resources

• Recycling of materials
