9It's not enough to just read about scientific concepts. Science and experimentation go hand in hand, especially when it comes to slime and other gross things! The experiments in this book offer engaging and achievable methods of learning about essential topics. Each investigation details the common ingredients needed, the degree of difficulty, the time it takes, and even the expected amount of messiness! Fun illustrated characters, including Professor Albert and Greg the Robot, accompany readers in their experiments and remind them how to complete each activity safely and successfully as well as what the conclusion means.
