I am always using this website to fill in any gaps in knowledge and reinforce concepts I haven't covered in a while. I recently used this article before doing an experiment with electromagnets with 4th graders. Having not taken a physics class in years, this site really helped because the content is very easy to understand. It is clearly and coherently organized addressing each subconcept in a very logical order. Each section offers great visuals and short videos which further explain the concepts. There are ideas of experiments to try at the end as well. The suggested websites at the end of the article are great. They really helped narrow down a potentially extensive search to a few credible sources.

Time spent reviewing site: I use this website all the time. I spent about an hour reading this article, related articles, and viewing the videos.

The "How Stuff Works" website is fantastic. It is easy to use and navigate. It
is also a good place to jump to any new found questions. I spent 15 minutes with
this one and shared it with my wife as well (she teaches 4th grade). This site
definitely enhances learning and is easy to use.
