Global Warming Science and Model is our impressive instructional software on global warming and the resulting climate change. It provides a logical sequential series of engaging simulations of the important concepts needed to understand why global warming of the Earth is happening. These simulations along with the supporting information provided make the concepts involved much more accessible and meaningful to students than what can be found in text books and/or many web sites. The software also includes an authentic atmospheric/ocean coupled global climate model (GCM). This final simulation has a simple elegance. It is easy to use with clear understandable results; yet unleashes the incredible computational power of your iPad or recent desktop computer, and uses many advanced methods, to deliver compelling inference on the future of the Earth (note iPads older than 2014 are too slow to reasonably run the GCM module). The content for the software, and the included GCM, are based extensively on the technical reports of the Intergovernmental Panel on Climate Change (IPCC), NASA, and NOAA. Through our software this information is made readily accessible to students in order to provide them with a sound scientific understanding of how greenhouse gases provide our planet with the global climate we have and why it can change. It also provides students with insights into the many uncertainties involved in predicting the future of our climate due to the nonlinear complexities of the feedbacks mechanisms involved in the Earths dynamic climate system. This instructional software includes hands-on lessons and excellent off-line labs which together can provide weeks of curriculum for grades 8 to college; or which because of the software’s module design, can readily be used with other existing curriculum. With the content carefully layered and differentiated so that it will be effective for learning at numerous levels of education and abilities. This software will free up more of your time to discuss and assimilate higher principles and understandings. Consider how much more meaningful and comprehensible climate study discussion can be when your students have a sound working knowledge of the processes that are causing climate change. Our global warming software is well tested and is in use at many high schools and colleges around the USA and across the world.

Optical Path

Read full description

This program is designed to illustrate the laws of reflection and refraction of light. As the laser pointer moves, the laser beam enters from the upper medium into the lower medium. When the two media differ, both reflection and refraction phenomena occur. When the refractive index of the upper medium is greater than that of the lower medium, and the angle of incidence exceeds the critical angle, a fascinating total internal reflection can be observed. This program is suitable for primary and secondary school students to learn and understand the laws of reflection and refraction of light, allowing them to review and reinforce physics concepts through engaging interactive activities. It can also be utilized by teachers for classroom demonstrations, enhancing lessons with a more lively and dynamic approach. The program's key features include: 1. Demonstration of reflection and refraction laws when the upper and lower media differ: The angle of reflection equals the angle of incidence, and the ratio of the sines of the angles of incidence and refraction equals the ratio of the refractive indices of the lower and upper media. 2. Demonstration of total internal reflection when the refractive index of the upper medium is greater than that of the lower medium: When the angle of incidence exceeds the critical angle, all incident light is reflected back, with no refracted light. 3. Selection of five laser colors - red, blue, green, orange, and purple - each corresponding to a unique refractive index. Lasers with higher frequencies exhibit greater refractive indices.

Verdict

The call

The clearest difference is price: Optical Path at $1.99 against Global Warming Science & Model's $19.99. Optical Path also leads on device support (3 vs 1). Global Warming Science & Model's advantage is iOS requirement (12.0.0 vs 15.6). On update cadence, ads and in-app purchases there is nothing between them.
