Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the second of four Science Objects in the Ocean’s Effect on Weather and Climate SciPack. It explores the distribution of water and energy on Earth. The cycling of water in and out of the atmosphere and oceans affects Earth’s climates by influencing patterns of precipitation and by transferring energy between the oceans and the atmosphere. As water moves through the water cycle, it evaporates from Earth’s surface, rises and cools, condenses into rain, snow, or ice, and falls back to the surface. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it eventually flows back into the ocean. The water cycle connects the oceans to all of Earth’s water reservoirs via evaporation and precipitation. The ocean loses thermal energy due to the evaporation of water. This energy transfer drives atmospheric circulation as water moves to the atmosphere as vapor and eventually condenses, releasing thermal energy to the surrounding air.
Ideas For Use
Science Objects are two hour learning experiences teachers can use to enhance their understanding of a particular scientific concept. Teachers can access any topic “on demand” from the Internet. Topics are based on the science literacy goals in the national standards (NSES, Science for All Americans, Benchmarks, and the Atlas of Scientific Literacy) and tied to state standards.
Each Science Object provides an understanding of the science content by providing a structured set of learning experiences through simulations and practice assessments. Science Objects challenge teachers to explore and explain real world phenomena and are founded on the principle that learners must be challenged with a problem, observation, data, etc., in order to develop scientific understanding. Science Objects utilize the five phases of inquiry-based learning: Engage, Explore, Explain, Elaborate, and Evaluate.
Oceans Effect on Weather and Climate: Global Precipitation and Energy
- Outline the basic steps in the water cycle in terms of density, energy of the water, and the relative molecular arrangement and motion in each phase.
- Describe how energy is transferred to the atmosphere by heating from the ocean and by the evaporation of water and its subsequent condensation.
- Identify the Sun as the energy source that drives atmospheric circulation and the movement of masses of air and water from one place on Earth to another (via convection).
- List sources for the water cycle and identify the largest source.
- Explain the relationship between water, temperature, the amount of water evaporated into the atmosphere (and subsequently condensed), and the energy of the atmosphere at or near the location of evaporation.
Hi Anne -
Great topic! Have fun with your inquiry activities with your students. I recommend you search the NSTA L...
