  Lesson Plan: Is it Real Science or Pseudoscience? Mark as Favorite (16 Favorites)

  In this lesson, students will deepen their knowledge of the scientific method by learning how to determine if researched information is valid and if it should be used for gaining or furthering our scientific knowledge. Students will view the documentary “Mermaids: The Body Found”, a pseudo-documentary that was later reported to be a hoax by the Discovery Channel. They will then use a “Baloney Detection Kit” to analyze the authenticity of information presented through different media as scientific fact.
