When DS was into anatomy, we found this:

http://www.visiblebody.com/

It's free (although explicit...) I'm sure I'll recall some others.

That looks awesome. It appears to be a pay-for site now, although the prices seem pretty reasonable for what it is. Thank you.

Hmm. So it is. It was completely free a couple of years ago.

I'm doing the trial version of aurora Lippor's supercharged science. So far, too awesome. We've watched a 1 hour astrophysics presentation, very entertaining. There's been two experiments so far. Microwaving soap. Wyatt was very dissappointed. He saw the video and thought Aurora turned soap into food. If I knew how to post a video I made a clip that could be on AFV. I put the microwaved soap on the table and asked again, "you sure the soap turned into food?". He's excited, yes, yes. He touched the soap and it was hot so he put his finger in his mouth to cool it off and tasted, Ew, just soap. I got a lecture, a couple lectures that day. "don't put soap in the microwave again, mom.". "soap is for taking a bath.". I put the soap back in the bathroom and I'm still getting lectures about it.
Aurora redeemed her program in his eyes in her next lesson where she showed us how to make a great paper rocket. It flies better than any paper airplane. Today I turned it on to see the video on how to make a working toy hovercraft. Another great project. Caveat; it used a used cd. Wyatt started repeating the supply list and I told him clearly, we're not going to make this now. You better not use my good dvd's to try it.
It's not free. It's $35 month. I justify this saying he doesn't go to preschool, this is cheaper. And it's good quality. What I'm debating is that he gets something out of it. He is learning and enjoying it. But like there's so much in the lessons he's not going to get, they are packed full of education. She's a rocket scientist and she did a good job. Maybe I'm overthinking it. I'm thinking about holding off until he's old enough to get the full effect out of every lesson. Odd comparison but I'm thinking they send young kid's to church when they can't grasp the whole thing but they're still getting something out of it and having a good time.
I'm going to finish the one month trial and make my decision from there. I'm impressed with the program. It says for grades k-12. For me I'm just debating when. I better tell her I mentioned it here since I told on her experiments. I'll tell you guys she does have a referral program which I am not a part of, I'll let you know if I ever am. I'll tell you up front anytime I might make a few cents on any suggestion.

Iucounu, I like that you're editing the head of the topic. If you're able to edit the title of the posting, maybe rename it simply as "Science Website & Resources" and then maybe we can get to be a sticky. (Essentially you'b be a "moderator" because you're the owner of the first post.) This is how they do it on a hobby site that lurk on and it works pretty well...

Just a suggestion.

The Photographic Periodic Table (Theodore Gray pics from book)
This site includes 3D/Rotation of some of the element samples. The site is also selling various products, most notably his book, but as many of you know... the book is great so I don't mind the pitch...

We like this: www.beestar.org. DD has been using the science and math program.
Beestar offers worksheets. They are full of vivid picture, all real life world problems, challenging stuff to help kids thinking. Pretty cute.

It doesn't seem to be in the cards, unfortunately. The OP is updated with the new info.

I haven't checked out these sites, but they're are listed at ds's school's website -

All sites are free -

This is a free site DD loves. It's great for the younger set. She especially loves reading the science articles and the food chain game.

These are all great additions. Added, and thanks to all of you!

Have you tried Body Browser from google labs? It looks great on my pc from work on Google chrome. Not so hot on my Mac at home. http://bodybrowser.googlelabs.com

Hi, I had started a thread because I didn't find this one by searching. I'm just going to cross post what was added to that thread if that's ok...

Science websites that you love for reference, entertainment, beauty?
Just reading a thread on birding that had a link to enature.com which I have never come across in my surfing for neat things for my DS5. I searched for one of those "ultimate" threads on this topic but didn't find any, so here goes. I'd love to get links to science sites people love, as I said, for reference, entertainment, beauty. Here are some of mine off the top of my head, I'll have to go digging for other favs.

http://enature.com
and links therein to all kinds of NASA information, images and video. Discovery going up for the last time today made me teary.
http://www.stellarium.org/ amazing planetarium software that you can download and run. you can zoom in/out, run time in forward and reverse, many more options that I haven't explored.
http://missrumphiuseffect.blogspot.com/p/thematic-book-lists.html great science and nonfiction book recommendations, and fiction as well
http://www5.pbrc.hawaii.edu/microangela/index.html electron microscopy images, limited explanations but beautiful
http://www.tolweb.org/tree/phylogeny.html this site is extensive but still a work in progress. many pages have large link lists to university and museum web resources

http://learn.genetics.utah.edu/ has some amazing videos and interactive graphics about genetics and molecular biology. a particularly great one is: http://learn.genetics.utah.edu/content/begin/cells/scale/

http://www.zooniverse.org/home
A set of citizen science projects. Use real data and find new planets using Kelper telescope data, help map the moon, look for new galaxies. These and other activities based on neat data-heavy science.
