Lessons of the Lorax
Fifth graders read a story that is about the brown pelicans. Then they use the story narrative in order to apply it to the concept of adaptations in different species. The benefits of certain adaptations is examined.
Curated OER
The Ocean Floor
Fifth graders discuss the process of sedimentation and the continental drift theory. They locate major structures on the ocean floor and they identify life forms at each level of the ocean.
Curated OER
World Wide Winds
Students recognize that global winds move in specific directions in specific latitudes and describe that in a written form. They relate the motion of the wind belts to historical navigation.
Curated OER
Winds Go Spinning Around
Students simulate the Coriolis Effect to comprehend why winds in the Westerlies are prone to cyclonic and anti-cyclonic motion. They arrive at an explanation of processes that drive world wind patterns
Curated OER
Tanker Spills
Students predict the flow of an oil spill and depict it on a map. They explain the predicted route of the oil spill using knowledge of ocean currents in a short presentation to their peers.

Fossils and Geologic Time
Students explore the development of the geologic time scale. They examine the major time periods in earth's history. Students discuss the role fossils play in helping us understand history.
Curated OER
EggCELLent Diffusion
Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.
