Animals of Japan; Geology/Geography of Japan

We watched several "travel video"-type movies about Japan during this unit, and our favorite was probably this one from "The Little Travelers." It's made from the viewpoint of two little girls traveling (alone, they make it seem like) around Japan. Daisy and Junie especially liked it. There are funny parts where the little girls try new foods or play with other children, and it just gives a feel of "this is real life in Japan." It was cute.

We talked a lot about Japan's geology, since it is so exciting! Hot springs, volcanoes, earthquakes, tsunami…all things the children are interested in. We had watched some videos of the 2011 earthquake and tsunami during our Natural Disasters Unit (you can find links here) so we looked up those and watched some of them again. The power of those huge waves is truly amazing.

We also thought the pictures of the earthquake's aftermath, here, were very interesting.

Here is an episode of Begin Japanology about Japan's volcanoes.

The children, naturally, also loved learning about the Shinkansen or bullet train. They've loved all kinds of high-speed trains ever since learning about them during our Train Unit, but we talked more about the TGV than we did the Shinkansen at that time, so it was fun to learn more about this specifically Japanese innovation. We learned that the Shinkansen was developed by a man who made kamikaze fighter planes (with no landing gear, but with streamlined fronts suited for dive-bombing ships) during World War II. He used the streamlined nose designs from the planes to inspire the distinctive front end of the Shinkansen. This was a good video about the Shinkansen, and this video about how the workers clean the trains in only seven minutes was interesting too.

Japan has many interesting animals, but we were most interested in a couple specific ones: the Japanese Macaques or snow monkeys (the ones that like to sit in the geothermal pools—we're always seeing pictures of them) and the bunnies of Bunny Island.

We quite enjoyed this movie about the Snow Monkeys. It's your typical kind of nerdily-dramatized nature documentary (narrated by Liam Neeson). Be aware that does show some monkeys mating. And a baby monkey dies. :( But the monkeys are so cute! We loved them.

Speaking of monkeys, my friend Carrie Ann told us about her visit to this monkey park near Kyoto. It was in one of the travel videos we watched too. It looks so fun! We would love to go there.

Bunny Island is a tiny island in Japan where there is a huge colony of semi-tame rabbits. They think some rabbits were maybe left there by schoolchildren a long time ago, and then multiplied? Here is some of the story behind it. It looks like a place I would love to visit. So many bunnies! There are lots more pictures and videos:  Hereherehere,  here and even more here.

Tsunamis (and other waves)

We quite enjoyed learning about tsunamis! Because of recent tsunamis in Japan and Thailand, there is a LOT of video footage of these huge waves. And as awful and terrifying as these events were/would be to experience, it is undeniably fascinating to see the pure power such enormous waves possess! Sam previewed the videos for us to make sure there was nothing too disturbing for the children to see. (In fact, if anything, they were a little TOO enthusiastic about the videos---I tried to impress upon them that real people are affected by these disasters, but it's hard to overlook the amazingness of those waves!) I said I hoped no one would have nightmares, and Malachi said it was going to give him goodmares. Hmm.

We did an activity to compare the origins of waves---regular waves, which are caused by wind, and tsunamis, caused by earthquakes. We got the idea for the tsunami-maker from this book.

You can find more resources on waves here.

To make your tsunami model, you cut out the bottoms of two nested foil pans (you could use just one, but two is more stable). Then cover the hole with duct tape. I can't remember what happened here---maybe we ran out of duct tape? You can see we used packing tape for the bottom side and duct tape for the top, so ours wasn't totally watertight.
Fill the pan with water, and proceed to experiment! First we set our pan down and blew on it with straws, making wind waves. We got some pretty big ones.


Then, we held the pan up and hit the flexible bottom part (the tape) from underneath to create tsunamis. You can really see a difference in the size and type of wave created by a disturbance under the water (an earthquake) rather than a disturbance above the water (wind). The earthquake waves are much taller and stronger because of the sheer amount of water they displace! We were inside the house (with towels) so I didn't allow the tsunamis to get TOO enormous, but I imagine you could do even more with this activity outside on a warm day! :)

Here are some of the tsunami videos we watched:

This video is a longer one that shows some of the footage from these other links. It's an entire program so it discusses how tsunamis form, etc. 

Some description of what caused it in this one

The bigger wave comes in near the 5:00 mark

This one gets interesting around the 4:30 mark

Newscast that shows some helicopter shots


This is interesting because it shows what the waves look like before they get to land.



This one really shows the power of the water, but it does show some little kids screaming and crying about halfway through (they're safe, just scared)



Showing the aftermath
