"Combining ever-popular slime with a nod to social media, this early reader in the Makers Make It Work series keeps beginning science fun. Young Leo has many hobbies, but his passion is making slime. He even has a dedicated website, where he posts videos of slime-making methods and tricks and has a line of customers asking for his creations. Leo's only regret is not being a better student in science. He's reminded of this weakness when his classmates show up with extra credit and he has nothing to share. But when his observant Muslim American and hijab-wearing teacher learns that Leo's friends call him the 'Slime King,' she uses the opportunity to show how making slime involves chemistry, building up Leo's confidence in science in the process. Sidebars in the form of green slime splats fill in chemistry facts. Adding appeal are colorful, exuberant illustrations, visuals of slime ingredients and slime types (e.
