Confession: Just SLIGHTLY obsessed with the U.S. Botanic Garden's corpse flower livestream. "Once fully open, [it] may remain in bloom for 24 to 48 hours, then will collapse quickly."

+Carol from California Definitely understand that sentiment, but the two paths could actually compliment each other—a lot of very important (and potentially helpful) technology comes to us via the space program.

Is it possible to create something like a friendship with the scorpion not only getting used to you but also expressing somehow that it likes you?

They pack and amazing amount into a small space! There is a lot to do and see here that is extremely unique. The Amazon exhibit is awesome and well maintained. They have an incredibly modern and up to date planetarium show as well which is included with admission. They have great student discounts and an additional 5 dollars off with a brochure add that can be found at most hotels in the areas. I was able to save $20 off admission for 2 students total. I would highly reccomend checking this out. It was one of my favorite museums I have visited.

I finally got to visit about a year ago. This museum always inspired knowledge when I was a child. I remember since the Planetarium for the first time, and was just amazed. I think I studied astrology for a year after that experience. The new museum even goes further. The generation today is in for a real treat. Job well done!

This was my first time visiting the Academy of Sciences, which I was interested in seeing because it looks great from the outside. However, for numerous reasons I was quite disappointed and did not think it was worth the price of admission. 1. Penguins and alligator should not be there. I felt terrible for the penguins and alligator. Anybody who considers themselves an animal lover should not go here. Is anybody really learning anything about the alligator when you can see them on tv or visit them in their natural habitats? We are teaching kids that it's acceptable to interfere with animals and keep them locked up in captivity so people can point and stare at them for 30 seconds. 2. Way too many kids running around. I felt like it was an afternoon day care. 3. Price of admission. 35 bucks for one adult ticket? Seriously? I spent 2 1/2 hours there and saw everything I needed to. I kindly asked the guy at the counter if I could get a AAA discount, but instead was told I had to go in person to a AAA branch office to get a discount. If you're short on time I recommend go see the De Young Museum, or the Botanical Garden.

(Review from my 5-year-old daughter) I really love it, especially the earthquake part. When I was about to go to the shake house, I got very scared, but it turned out to be not scary at all afterwards. When I went to the rain forest, I really wanted the butterfly to land on me. At the aquarium, I saw two divers, and I high-fived with them :)

Hit the aquarium(bottom) or top floor first if you want to explore right away or aren't in the mood for extensive lines(mostly for the 2 ground floor attractions). teacher discount for my cousin for some reason! We were told that most offered discounts come with sponsored bus trips to there and whatnot. But yeah. Albino alligator.

Great spot for the family, but also for adults. My first time here was for one of the Academy of Sciences After Dark events, where it's adults-only and they sell alcohol inside. It makes it fun to go after work with coworkers or friends. We went as a group for a team bonding event. There's quite a bit to see and the tickets were only $15.

Great place to take the family. Plenty of awesome learning opportunities. The planetarium and the rainforest exhibit are pretty amazing. I also enjoy the weekly night life events that they host, although the fire alarm went off during the last night life event I went to causing it to end quite early...

This is, without a doubt, the best natural history museum on the West coast and one of the best in the United States. On a summer trip to San Francisco from the east coast, I took the time to visit the museum and ended up spending the entire day exploring the exhibits. The planetarium shows are fantastic and they work closely with the American Museum of Natural History in New York City to put on shows. The tropical bio-dome was amazing and the collection of sea life is astounding. The scientists are there to answer your questions and sometimes let you go hands on with the animals! This museum really gives you an appreciation for the natural world. It's a must visit!
