I read this book when I was in 2 grade and I did actually enjoy it. because I really liked science. I had a lot of scientific questions when I was in 2nd grade and this book answered the questions. But it didn’t only say how to extract something from something or why does cat’s eyes shine when it’s dark. But it also says about my favorite topic to talk about how dinosaurs became extinct or what each dinosaur is. I think this book made me go from a boy with a big question mark in his head to a boy who could erase the question in another boy’s head which made me feel smart. Especially about dinosaurs. But, more than 6 years passed and i almost forgot everything in this book so i read this book again and now i’m a boy who erases the question marks in another boy’S head. But people might already know the answers.
