Eddie the Electron Moves Out
Eddie the Electron is part of a helium atom. His helium balloon popped. He goes out a window. Then he flies up into space because he is lighter than air.
I’d like to hear more about the fission event that makes helium. Why is Eddie in the picture with thorium and uranium if helium doesn’t exist yet? Thorium looks worried. Where does uranium go? Why is thorium still there and uranium gone after they explode?
It takes a long time to make helium. It’s a non-renewable resource. You can’t get it back. (I wonder if someone can figure out how to get the helium out of the upper atmosphere.) Helium is used for important stuff like MRI scans. I definitely will not use helium balloons.
After reading the book, I wonder what is going on. Why is there a key in the earth’s crust? What are the balls in the air? I’d like more labels on the pictures. There are a lot of end notes in this book. They kind of interrupt the story, but they are interesting. I think I like science books with more science and less story.
