This helps to contextualize the concept. I would show this video as I introduce the concept. ]]> 2019-03-28 20:41:15 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346338582 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346345736 Instructions: Turn off the lights, take a wintergreen Lifesaver candy, and bite down! Ask a classmate if they saw any light flash. This is a fun activity that shows students something they may never have seen before. ]]> 2019-03-28 21:09:31 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346345736 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346346244 Unfortunately, the experiment may not work if the room isn't dark enough; this video shows the same concept. I would show the first half of this video after trying the experiment. ]]> 2019-03-28 21:12:13 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346346244 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346374450 Bioluminescence is the ability of a plant or animal to produce light. This web page goes over the details of how bioluminescence works, and some of the reasons why organisms have it. In class, students can take a couple of minutes to skim this article. ]]> 2019-03-28 23:54:28 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346374450 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346638492 This website contains two flash player simulations that allow students to play around with colour mixing, and to observe how different inputs affect the colours they see.  ]]> 2019-03-29 17:06:38 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346638492 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346642610 This website contains an interactive simulation that allows students to see certain characteristics of different waves in the electromagnetic spectrum, including wavelength, frequency, energy, and brief facts regarding each type of wave. This software allows students to have a chance to observe differences between waves; the fact that the waves are displayed as an animation means this website is more visually stimulating than a page from a textbook. ]]> 2019-03-29 17:18:04 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346642610 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346651243 The idea of a virtual image is a confusing one for Grade 10 students, but it is essential that they understand this concept to reach the other contents of the unit. This video, from Khan Academy, explains the concept well, in language that is accessible for all learners. ]]> 2019-03-29 17:39:35 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346651243 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346655511 This simulation can serve either as an introduction to curved mirrors, or as consolidation after the concepts have been introduced. It allows students to observe what happens to an image as it moves around, relative to the focal point of the mirror. ]]> 2019-03-29 17:50:42 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346655511 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346706456 Similar to the Concave and Convex mirror simulation, this website allows students to see what happens to the image of an object when viewed through a convex lens. ]]> 2019-03-29 21:08:25 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346706456 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346706879 This video explains how telescopes used to work, and how they are built today. This provides students with a real example of an application of curved lenses and mirrors. ]]> 2019-03-29 21:10:33 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346706879 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346707604 This experiment, taken from NASA's website, allows students to attempt to build their own pinhole camera at home. ]]> 2019-03-29 21:15:48 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346707604 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346707938 This website contains a variety of activities related to optics that students can explore. ]]> 2019-03-29 21:18:21 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346707938 bjenn019 https://padlet.com/bjenn019/2g27wsryz21q/wish/346708338 This video, similar to the video about telescopes, provides students with yet another example of a real application of lenses. This one is likely to be relevant to at least a few members of the class. ]]> 2019-03-29 21:21:31 UTC https://padlet.com/bjenn019/2g27wsryz21q/wish/346708338
