Understanding Salinity
Middle schoolers discuss why the ocean is salty. They discuss what salinity is. Students are told that is they want to know how much salt is in a body or water, they would use a special scientific tool. They complete an Estuarine Layers...
Curated OER
Parl Ranger in Training
Young scholars develop a research presentation about rock formations and natural erosion. Using traditional and online resources, students gather and organize information about rock formations. Young scholars use their information to...

How Does Water Cause Weathering?
Fourth graders explore the weathering process of water on rocks. They observe how water and friction from other rocks cause them to weather. Students discuss examine and discuss various rocks found on the playground, beach, etc. They...
Curated OER
Cracked Marbles
Fourth graders determine how weathering, specifically ice, snow, and freezing water change the Earth's surface and rocks. After completing the investigations, they explain how heating and cooling expand and contract marbles until cracks...

Erosion in Different Soils [Erosion Races]
Fourth graders review how erosion can happen by wind, water, and gravity which they studied in previous activity. They attempt to discover if all soils erode at the same rate. In small groups, 4th graders experiment with three different...
Curated OER
Physical Science Fun
Fifth graders explain how the land changes by developing some "land dances." Working in cooperative groups, each group develops a movement sequence that depicts the vocabulary word they are given. They teach dance to other classmates.
Curated OER
Cemetery Geology
Young scholars examine the chemical and physical weathering process of different rocks in a cemetery based on dates on the stones. Students discover the susceptibility of different rock types to weathering.
Curated OER
Weathering and Erosion
Sixth graders discuss the differences between chemical and mechanical weathering. Using that information, they create a concept map showing the forces that cause these types of weathering. After participating in an activity, they...
Curated OER
Secrets in a Grain of Sand
Learners working in small groups examine beach sand to discover signs of erosion, weathering, ocean currents and waves. They present their findings to the class.
