This site is a perfect resource for researching or learning more about different types of energy. It breaks them down by renewable or non-renewable, using and saving energy, history of energy including timelines and famous people involved with energy, and there is even a games section! There are science fair experiments which are perfect for this time of year, photo journals about Energy Ant's visits to various types of power plants, and even a printable scavenger hunt. Lesson plans and a teacher guide are also available on the site. A great way to introduce or research or compare different types of energy. A perfect follow-up from this site would be to play Power Up which I posted about here.
