【国立科学博物館公式】知るほど、ハマる。 －企画展「ワニ」解説動画－

Picked video by video from National Museum of Nature and Science, Tokyo (mixed channel): title plainly names a teaching subject. Channel transcript sample: One sample is an exhibit-promotion/fundraising interview with no real subject teaching, one has no transcript, and one is a genuine curatorial explainer with a researcher teaching biological concepts via specimens.
