A scientist or even an ordinary citizen might discover a problem, and scientists use the process of scientific inquiry to find the solution. In The Case of the Vanishing Golden Frogs: A Scientific Mystery, author Sandra Markle tells the true story of how biologist Dr. Karen Lips discovers that golden frogs are vanishing and works tirelessly to solve the mystery, using the help of researchers in other scientific fields.

In this brief exploration, students will view a slide show and watch a couple of videos to learn about the Panamanian golden frogs and frogs in general. This teacher sheet provides you with anwers to the questions.
