Super fun and various levels of questions using text evidence. This was the first year we did this book in 4th grade. It is all about Slime and the main character is a 4th grader who loves science. There are slime experiments in the back of the book, which we did as a class. The children LOVED it! These questions are grouped by 3 chapters. There is a quiz and a SLIM recipe to make at the end. Worth it!!!!
