The Water and Landforms Module provides students with experiences to explore properties of and changes in Earth's water, slow changes to Earth's land, and daily, monthly, and yearly patterns of change on Earth. In this module, students will:
- Observe and explain the interaction between masses of water at different temperatures and masses of water in liquid and solid states.
- Construct a thermometer to observe that water expands as it warms and contracts as it cools.
- Investigate the effect of surface area and air temperature on evaporation, and the effect of temperature on condensation.
- Use stream tables to investigate how the slow processes of erosion and deposition alter landforms; predict the results of a student-designed stream-table investigation, and then compare actual results to predictions.
- Examine properties of soils and investigate what happens when water is poured through soil and gravel.
- Analyze observational data to discover the sequence of changes that occur during the Moon's lunar cycle, in the Sun's position in the sky over a day, in tides over several days, and in seasonal weather patterns.
- Use weather instruments to measure temperature, atmospheric pressure, humidity, wind conditions.
- Interpret the data displayed on weather maps and look for patterns over time to make predictions.
