Packed with ideas across most physics- a good purchase even for an adult.
Format: Paperback
Great information density! I though they did a good job of covering the basics to a higher resolution than I expected. I bought this for my 10 year old nephew, it's a bit out of his reach as far as information density- the pictures help a great deal but it is definitely a book that will require explanation for you ger children. I don't think it's ever too early to have exposure to this science.

Really great basic/intro to physi
Format: Paperback
Purchased as a birthday present for my very smart 14 year old grandson. The book gives simple discussions about most basic elements of physics. I’m hoping it is not too simple but not too complex. First look tells me I made a good choice. I may buy another one just to have around the house for other grand kids. I’ll give an update after he gets into it a bit.
