Standard: K-LS1 From Molecules to Organisms: Structures and Processes

Students explore how animals meet their basic needs by sorting living and non-living things. They identify survival patterns, compare animal needs to their own, and classify animals as herbivores, carnivores or omnivores.

Standard: 1-ESS1 Earth's Place in the Universe

Students explore the moon's changing position, shape and brightness, observing how it looks at different times of day and night. They learn that the moon follows a predictable rising and setting pattern.

Standard: 2-ESS2 Earth's Systems

Students explore how erosion shapes the environment and how scientists and engineers prevent the damage caused by wind and water. They compare real-world solutions and design their own ideas to reduce erosion.

Standard: 3-PS2 Motion and Stability: Forces and Interactions

Students explore how motion changes during a skydive and what forces help a skydiver land safely. A hands-on parachute investigation shows how air resistance slows falling objects.

Standard: 3-5-ETS1 Engineering Design

Students follow the Engineering Design Process to plan, build and test a model irrigation system for a school vegetable garden. They reflect on their designs and propose new irrigation methods.

Standard: 5-ESS1 Earth's Place in the Universe

Students learn about the movement of stars and the history of constellations. They build and illuminate a model constellation and investigate how star patterns shift throughout the year.
