Meerkat Manor is an entertaining and educational animal documentary. This product includes questions for 13 episodes. I got hooked on this series by my 90 year old grandmother. She calls it the daytime soap opera of Animal Planet. These are great homework assignments. Episodes are usually about 25 minutes in length. The study was conducted by Cambridge University. FUN homework assignment for biology, ecology, research and zoology students. I always get the students started with a class preview.
