Drinking Water
Provided by: MIT OpenCourseWare |Published on: March 30, 2023
Videos Grades 9-12, ap-college
Synopsis
- This recorded college lecture explains the importance of molecular orbital structures and orbital hybridization using the real-world example of filtering pollutants out of water.
- Students will learn that access to clean drinking water is a critical issue for billions of people around the world and that water filtration, particularly desalination, is a difficult and expensive process.
- Students will also learn that graphene is a promising material to use as a membrane in water purification due to its molecular structure.

Teaching Materials
Positives
- The professor takes the time to set up the issue of water quality and establish the scale of the problem globally.
- The video includes visuals like maps, graphs, and diagrams to aid in student understanding.
Additional Prerequisites
- Some content presented is copyrighted and is not in the public domain.
- The video and transcript are available to download.
- The video can be opened on YouTube to watch with closed captions or subtitles.
- Students should already be familiar with atomic orbital shapes, molecular orbital theory, hybridization of orbitals, and sigma and pi bonding.
Differentiation
- The chemistry topics referenced in this video are typically beyond the scope of AP, IB, or advanced high school chemistry courses. This resource is best suited for college-level students.
- Before watching the video, teachers should discuss the orbital structures of benzene and graphene, paying particular attention to the pi bonds.
- This video was recorded in 2018, and since then, there have been numerous advancements in the use of graphene as a membrane. Students can research how they are being used today and where scientists are looking to take these membranes next.
- Many new technologies are being explored for desalination, which students can research and compare to graphene.
