The science units in fourth grade include the Solar System,
Circuits & Pathways, and Investigating the Changing Earth.
Descriptions of each unit are provided below:
become familiar with objects in our solar system. They gain a
perspective on the physical relationship between objects in the solar
system. Students model planets, combine astronomy and geometry to study
ellipses and planetary orbits. Students study stars and their celestial
patterns. They also observe moon phases.
Circuits and Pathways
explore the properties of electricity in simple circuits. They use
motors, batteries, wire, bulbs, and switches to explore the concepts of a
circuit, contact points, and multiple pathways.
Investigating the Changing Earth
explore changes in the Earth's surface caused by weathering and
erosion. Using stream tables they develop explanations for delta
deposition, canyon formation, floods, and other stream-related
