This page goes through an explanation of the physics of many common rides at amusement parks. It could be used to gain the interest of students to new topics to be presented in class.
This page gives links to many resources which could be used to enrich physics instruction at the secondary level. Some examples of the resources are an examination of the physics of race cars, roller coasters, and links to some simulations.
This page lists some misconceptions which have been taken from college Physics students' essays and exams. It could be a good tool to show students that even college physics students have basic misconceptions and use this to emphasize the importance of knowing the basics very well.
This web page is from the UIUC Physics Van and it is a place where people can ask questions about things in their everyday life and get answers from people who are knowledgeable in related scientific fields.
This is another site full of good physics simulations which could be used to help students explore different topics in physics. These simulations may explore topics which are too complicated for students to directly explore in classroom experiments, or topics which are typically confusing for students.
