Positives

• The video uses animated diagrams to convey key concepts.
• There are questions, additional resources, and discussion prompts that accompany the video.
  

Additional Prerequisites

• Students over 13 years old can create a free account to save their answers and participate in discussion boards.
• Teachers can create a free account to customize the lesson and view student work.
• The video assumes students have a strong foundational understanding of geometry.
• In the Dig Deeper section, the link to the Nature article summary and the link to the Bill Nye videos are broken.

Differentiation

• In a math course, students could create their own mathematical models for how the billiard ball would move on a circular table from different starting points, as described in the video. The  Dig Deeper section includes multiple links to programs that can help students digitally explore these types of models.
• In a science course, students could gather additional evidence to decide if or when they think we will reach a climate change tipping point. Students could then present their findings to the class.
• Other resources about tipping points include this video by Grist, this video by Our Changing Climate, and this course by Climate Science.
