We have started our study about Noah's Ark and the Flood. We are using several books that are really good. My favorite for elementary kids is probably The True Story of Noah's Ark by Tom Dooley
For older kids or adults, Noah's Ark: Thinking Outside the Box by Tim Lovett is really good.
We also really liked Noah's Big Animal Adventure game. It is a big book that folds open for the game board. Spaces have lots of facts about the ark and the flood. Game pieces are very attractive paper animals. It is a very nice game.
We decided to get some paper arks from Answers in Genesis and my kids had fun putting them together. I wouldn't really recommend them for small children, though, since they were a little tough to get the flaps into the slots. Here is my 4 year old putting the ark together.
We also talked about the vapor canopy idea before the flood and I found a site with a possible pre-flood earth that I had my 2nd grader copy. I found the website author's ideas and diagrams of how the continents could have separated during the flood really interesting, and my son and I looked over the diagrams and discussed them. Here is a picture of my son copying the picture of the possible pre-flood earth.
Over the next couple of weeks, I will be adding more suggestions or ideas about Noah's Ark and the Flood, so check back!
