We recently started our unit on the Animal Kingdom. The first order of business was to read about cnidarians. (Why the eff is there a silent "c" here?!)
After coloring in their picture from the textbook and another one from here, we watched a video on youtube about jellyfish reproduction.
We also took a trip to the library and borrowed two books on cnidarians, Jellyfish Underwater World and Sea Anemones.
Later on we moved on to history, reading about the Phoenicians. The kids both colored a Phoenician ship, which we learned the Phoenicians used to travel the Mediterranean Sea in order to trade. The Phoenicians were great sailors, we also learned.
