Radiation – Properties of Light This page forms part of a larger website with an advanced examination of electromagnetic radiation. Users can feel free to visit any part of the site, but the focus of this annotation will be on the curriculum concept of properties of light. This page begins with a definition of electromagnetic radiation and its manifestation in the form of light. It then examines different kinds of light, such as IR and UV light. The page then examines many properties of light, including its visible spectrum, movements, speed, wavelengths, composition, intensity, and temperature. These discussions are accompanied by plenty of charts, images, and animations. The last sections outline historical research of light by Max Planck and Albert Einstein. The bottom of the page contains sections reviewing important terms and formulas. The page ends with a set of review questions. This is an advanced website. No cute images will be found here. Distinct sections are barely discernable as all the concepts are presented to users one after the other. There’s no navigation menu on the page, but that’s almost a non-issue. It still would have benefited from page links to important terms because as it stands now, users may have to sift through a lot of text. But, what remains is very good information that examines concepts both qualitatively and quantitatively. The charts, images, and animations effectively complement the advanced explanations. All important terms and concepts are bolded. Older students should have no problems using this page. The review questions are a bonus. This is a very good site for both teachers and older students to use. |

Name:
DiscoverySchool.com This site contains complete lesson plans for studying Earth Sciences at any level from K-12, including objectives and suggestions for evaluation in each lesson plan. Teachers can look forward to lesson plans on Earth’s surface, geological phenomena, oceans, weather, and tectonic plates, but this is by no means a complete list of lesson plans that can be found on this site. If that wasn’t good enough, many of the lesson plans even contain suggestions for adapting the lesson for different grade levels. This is hands-down one of the best resources for all teachers, and not just Science teachers. The site is colourful and well laid out. All sections of the site are accessible from the always-present menu. Some of the important concepts even have sound files attached to them so that you can listen to its pronunciation. This site is mainly geared towards teachers. |

Name:
The
Geological Society of America This site contains complete lesson plans for studying Earth Sciences at any level from K-12, including any required worksheets. Lesson plans are organized by specific topics in Earth Sciences. The section on rocks and minerals is impressive on its own. Lessons for each topic are also further subdivided by grade level. Most lessons appear to be lab-based and very hands-on. Finally, there are literally tons of links to other educational resources within each topic. This is another amazing resource for teachers, but definitely geared towards Science teachers only. The site is colourful and well laid out. There are so many lesson plans and resources that are listed that the site even provides a handy function to sort by topic or age group. If that wasn’t enough, the site also provides suggestions for readings and class discussions of critical issues. This site is mainly geared towards teachers. |
