This Space Elevator is another playful and cute project by Neal.fun. Scrolling up will take you on a trip to Space while exploring the atmosphere and its many layers, past high-dwelling animals and cruising altitude for aircrafts and different types of clouds. There's even a press play button for elevator music along the way as you ascend. I don't know if this is meant for children, but it's fun and educational for me too. — CD 

One of the best books I’ve read recently is Mendeleyev’s Dream: The Quest for the Elements, published in 2019. Although it is not a long book, there are 3 books coursing through it. One theme is the slow discovery of the primeval chemical elements. That story would be enough for most books. A second is the convoluted and incredible story of alchemy, which was amazingly persistent throughout the birth of chemistry. And the most important story is the slow emergence of science, and how difficult its birth was. I found news and insight on nearly every page, and am shocked at how little I knew about the most basic stuff that our world is made of. Highly recommended. — KK

NASA has a page dedicated to their Citizen Science Projects where you can volunteer to help make scientific discoveries, like mapping bird diversity, cloud gazing, tracing patches of kelp, or identifying celestial objects in search of Planet Nine. Currently, there are 30 projects open to anyone in the world, and most can be done with just a cellphone or laptop. — CD

When I was 12 I built a chemistry lab in my basement and have been doing chemistry since. But I learned more about chemistry from reading this trio of books by Theodore Gray than anything ever learned in school. That’s surprising because these volumes appear to be photo books, full of pictures of metal chunks, high-speed shots of chemical reactions, and photos of everyday stuff. But woven through these unusual photographs are the best explanations of how and why chemistry works. The best looking of the three is The Elements, a hundred portraits of our universe’s true heroes; the most informative and fun for me is Reactions, which reveals why matter works. Advance onto Molecules if you like these. I read them all with wonder. — KK

This website lists the astronauts in space right now, with links to their Wikipedia entries. They’re all in the International Space Station and come from Russia, China, the United States, and the European Union. — MF

The best source I’ve found for small samples of very pure elements – such as scandium, dysprosium, holmium, terbium, yttrium, uranium – including, yes, cubes of pure tungsten ($14), is Luciteria. Very reliable, thorough, and extensive catalog of all available common and exotic elements. I’ve been amassing a full collection of these universal atoms. — KK
