Sea levels could rise dramatically in the 21st century if a different course of action is not taken to supply our energy needs.Д«ut just how much energy can we capture from the sun? What do you think it depends on? Today's lesson will give us an idea of how we can use the Sun's energy and how to determine how much solar energy is available to us. Why? This is because the reliance on fossil fuels and wood is believed to lead to climate change, which has intensified severe weather events such as floods and storms. Many other communities that do have access to coal, natural gas, oil and wood have decided to use renewable energies such as solar power instead. These changes can occur on a variety of time scales from sudden (e.g., volcanic ash clouds) to intermediate (ice ages) to very long-term tectonic cycles.ДЄlignment agreement: Thanks for your feedback! The foundation for Earth's global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy's re-radiation into space.ДЄlignment agreement: Thanks for your feedback! Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.Дid you know that the sun can help us heat and light our homes, cook our food, and heat our water? In fact, many communities do not have access to fossil fuels or wood, which are typically used to supply our energy needs, and so people rely on the Sun to do all of these things! These phenomena cause a cycle of ice ages and other gradual climate changes.ДЄlignment agreement: Thanks for your feedback! The geological record shows that changes to global and regional climate can be caused by interactions among changes in the sun's energy output or Earth's orbit, tectonic events, ocean circulation, volcanic activity, glaciers, vegetation, and human activities. This lesson focuses on the following Three Dimensional Learning aspects of NGSS:ДЄpply scientific reasoning to link evidence to the claims to assess the extent to which the reasoning and data support the explanation or conclusion.ДЄlignment agreement: Thanks for your feedback!Д¬yclical changes in the shape of Earth's orbit around the sun, together with changes in the tilt of the planet's axis of rotation, both occurring over hundreds of thousands of years, have altered the intensity and distribution of sunlight falling on the earth. Use a model to describe how variations in the flow of energy into and out of Earth systems result in changes in climate.Д¬lick to view other curriculum aligned to this Performance Expectation Explain why solar energy is becoming more prevalent.Explain how solar energy is used in sustainable engineering applications.Calculate the amount of solar energy on Earth at a given time and location.Describe solar energy and why it changes with time and location.Engineers must understand the basics of solar energy and the Earth in order to incorporate solar energy into their designs.ДЄfter this lesson, students should be able to: This engineering curriculum aligns to Next Generation Science Standards ( NGSS).ДЄs the market for solar power technologies grows, determining the amount solar energy available at a given location is important for maximizing energy efficiency of solar technologies and determining if solar power is even a possibility for a specific region. The importance of determining incoming solar energy for solar devices is discussed. Students learn about solar energy and how to calculate the amount of solar energy available at a given location and time of day on Earth.
