Curated OER
Dunking Duckies - Endless Expansion And Contraction
Students use inquiry to explore how their dunking duckie bobs up and down. In this states of matter lesson, the teacher guides the class towards discovering how the dunking duckies continue to bob up and down for days without being touched.
Curated OER
Air Expansion and Contraction
Students observe that air exerts pressure, that heated air expands and that cooled air contracts. After the demonstration, students engage in a question and answer session about what they saw.
Curated OER
A Model of Three Faults
Learners investigate faults. For this science lesson, students explore the many stresses and strains in the earth's layers and research the types of faults in their state.

Investigation 3 - Weathering
Fourth graders study 4 types of weather processes: wind, running water, plant growth, and freezing water. They explain how the processes of weathering and erosion change and move materials that become soil. They draw diagrams...

Erosion Deposition Review
In this erosion deposition worksheet, students fill in 36 blanks to complete sentences about the formation of soil, the forces of erosion, physical and chemical weathering, sediments and soil deposition.
Curated OER
Soil Formation
In this soil formation instructional activity, students will review examples of chemical weathering and biological weathering. Students will also review the different soil layers and how they are created. This instructional activity has...
Curated OER
Weather and Wind
Students study wind and its effect on weather. In this investigative activity students write a report on wind and weather and create a movement sequence.
