Curriculum Outcomes involved:
- Earth and Space Science: Water System on Earth
- Waves, Tides, and Water Currents
- Carry out procedures in order to investigate how temperature differences in water cause currents
- Explain how waves and tides are generated
- Formulate operational definitions, on the basis of investigations of waves for: wave length, height, crest, trough
- Shorelines
- Explain how waves and tides interact with shorelines
- Waves, Tides, and Water Currents
- Physical Science: Fluids
- Floating and Sinking - Density
- Describe the relationship among the mass, volume, and density of solids, liquids, and gases using the particle model of matter
- Analyze quantitatively the density of various substances and suggest explanations for discrepancies in data, such as the measurement of the volume of irregular objects by water displacement
- Explain the effects of changes in temperature on the density of solids, liquids, and gases and relate the result to the particle model of matter
- Describe situations in life where the density of substances naturally changes or is intentionally changed
- Forces in Fluids
