DS8 watches BrainPop videos frequently. It is a great resource for us as homeschoolers. Portia is correct that there are LOTS of topics. Almost every topic we cover in our curriculum has a BrainPop video, and DS often remembers the material he learns on BrainPop better than material presented to him in other formats. The videos we watch are usually 3 - 5 minutes in length, so I'm not sure if we are watching different videos than Portia or if Portia's DS is using BrainPopJr? There are other resources available after most videos, including a quiz, activity, and additional written information. If you use these additional resources I think it can be a major learning resource (we do this for the health topics since we have no other health curriculum).
