EXPERIMENTIA @ Institute for Nature Study / Shirokanedai, Meguro ward
One Saturday morning in late February, My daughter and I joined the science open class for kids that was held by the National Science Museum. The theme of the class was "Let's watch the DNA!"... Off course you couldn't see the DNA at all even if you used the highest performance optical microscope, but you would see the fruction that includes DNA via some simple scientific procedure.
2. Grind down well the buds in a mortar.
4. Percorate the water layer using gauze.
5. Add ethanol gently, then the DNA fruction is separated out into the alcohol layer (DNA are soluble in water, but insoluble in alcohol).
6. Get the bundle of DNA out. 
Can you see the white sediments in the tube?
Ladies and gentlemen, (drum roll) this is (a bunch of) DNA!! Give them a big hand!(approse)
Thank you , Hamao-sensei. We enjoyed your class very much.
This class was held at "Institute for Nature Study", one of the branch institute of the National Science Museum, located in Meguro-ward. Believe or not, it's a real forest surrounded by Tokyo concrete jungle. 
Actually, I've intrroduced some gardens(Rikugien, Furukawa-teien, etc) as the nature spot in Tokyo on this weblog, but they were sort of "artificial nature". I didn't know there was a such kind of real nature reserve in the center of Tokyo. I heard that this place has been designated as a national natural monument since 1949.
Look! Daisagi(great egret) is there!
"If you're lucky, you can come across Kawasemi." A bird watcher who talked with us said so. Coming across Kawasemi in Meguro-ward? Really?
Institute for Nature Study: The closest station is Shirokanedai (Metro, Namboku-line), 4min walk from exit #1. You can also get there from Meguro station east exit (JR Yamanote-line), it takes about 7 min on foot. Open hours are 900-1630, except for every Monday.
Materials
Broccorri, saline, ethanol, detergent.
Methods
1. Collect the broccorri buds using a dissecting scissor. (the cell density of bud is extremely high. It's a very good material for this experiment.)
2. Grind down well the buds in a mortar.
4. Percorate the water layer using gauze.
5. Add ethanol gently, then the DNA fruction is separated out into the alcohol layer (DNA are soluble in water, but insoluble in alcohol).
6. Get the bundle of DNA out.
Result and Discussion
Can you see the white sediments in the tube?

As you said in your mail, it seem to be a very nice place.I will try to go next time. For your information, Matsuoka Art Museum is just next to this place. The oriental art collection in this museum is so nice and worth pay a visit.
