Greenhouse Effect screen shows Earth's atmosphere. Goals Students should be able to do the following: 1. Point to the Today radio button. Teaching Ideas Tips for Teachers There is no teacher's guide for this simulation. Many red photons get redirected back downward as they encounter greenhouse gases. This activity can be used in conjunction with the Greenhouse Gas Demonstration.
Here, we have an option to add Glass Panes to the simulation. In the third simulation, students can adjust levels of atmospheric gases, then shoot infrared and visible photons from a photon emitter. Click on Adjustable concentration button. Repeat with the yellow particle. Observe the vibrations of the molecules.
Users may opt to add cloud cover to the simulation to observe the resulting temperature changes. In their research, Finkelstein, Perkins, Adams, Kohl, and Podolefsky 2005 state that students who learned material through computer simulations outperformed on conceptual questions when compared to students who used real equipment. Makes grants to address the most serious social and environmental problems facing society, where risk capital, responsibly invested, may make a difference over time. How much an object's temperature increases depends on how intense the light striking its surface is, how long the light shines on the object, and how much of the light is absorbed. This helps to understand the effect of Glass Panes on atmospheric temperature.
Click on Glass Layers tab. Please visit this site Choose the minute and second where you have the question. Ideas and Activities for this Sim. Please refer to the style manuals in the area for clarifications. Slide Number 7 Greenhouse Effect Greenhouse Effect It is a phenomenon in which, earth's atmosphere traps radiation emitted by sun. This activity was selected for the On the Cutting Edge Reviewed Teaching Collection This activity has received positive reviews in a peer review process involving five review categories.
During any transformation of energy, there is inevitably some dissipation of energy into the environment. Point to Greenhouse Gas Composition. Note the composition of greenhouse gases. Drag the slider to change the speed of the animation from fast to slow. In a second simulation, the Greenhouse Effect caused by glass is illustrated. At the prompt type cd Downloads and press enter.
I believe that your lesson will allow the concept of greenhouse gases to be visualized by students as this is a concept that cannot be tangibly seen. Follow the paths of several photons of each type and report any differences you notice. More information on this mission is available at this link. Add cloud cover to the simulation and observe the resulting temperature changes. This mechanism keeps the energy of the sun trapped in the Greenhouse.
Engage Ask your students what they have heard about the greenhouse effect. By burning fuels, people are releasing large amounts of carbon dioxide into the atmosphere and transforming chemical energy into thermal energy which spreads throughout the environment. Energy from the sun and the wind and water energy derived from it is available indefinitely. Effect of Glass panes and Clouds on atmospheric temperature. King Saud University seeks to become a leader in educational and technological innovation, scientific discovery and creativity through fostering an atmosphere of intellectual inspiration and partnership for the prosperity of society.
One goal in the design of such devices is to make them as efficient as possible—that is, to maximize the useful output for a given input. C Human Impacts on Earth Systems Part One Goal: Students will learn how greenhouse gases temporarily trap heat within Earth's atmosphere, warming our planet via the greenhouse effect. The radiated heat from Earth's surface is shown as red infrared photons. Over time, the thermal energy tends to spread out through a material and from one material to another if they are in contact. Simulations were designed using principles from physics education research and refined based on student interviews and classroom observations. Teaching Materials Microsoft Word 45kB Jun15 11 Microsoft Word 63kB Jun15 11 Assessment Ideas for Microsoft Word 50kB Jun15 11 Connections to other Activities This activity is one of a designed to address the concepts that address how the greenhouse effect influences global temperature which can be used individually or combined as desired.
For more details, please write to us. Slide Number 8 Greenhouse Effect This effect is caused by gases in the atmosphere. How do the gases influence photon absorption? Thank you for this lesson contribution to the class! Click on Adjustable concentration button. Slide Number 15 Assignment As an assignment, 1. With the advent of increasingly new technology, scientific facts and concepts can now be produced visually on digital screens. Please note that this resource requires at least version 1. Drag the slider from fast to slow.
On the right-hand side panel, we have options to explore the atmosphere. From the options menu, click to add clouds. Thermal energy is transferred through a material by the collisions of atoms within the material. Hi Darren, I enjoyed reading your lesson outline. Observe the temperature on the thermometer. This page first made public: Jun 29, 2011 This activity is part of the of teaching materials on climate and energy topics. In the future, we will add other tabs providing more detail about particular greenhouse gases and to address the enhanced greenhouse effect generated by human impacts on Earth's environment, primarily the burning of fossil fuels.
