You will need a BrainPop password to access a couple videos. But overall does not impact the totality of the ppt.
The following Powerpoint is used as a complete teaching unit plan. This is a comprehensive unit with 54 slides that took me over 8 hours to complete. This is what I use in my class and has been very successful. There are many interactive sites, standard-based information, and links to resources/videos. This can take 3-4 weeks to complete if you wanted it; lots of information and resources!
