Autumn leaves are one of nature's most brilliant displays of color- but what causes them to turn from green to the bright oranges, reds, and yellows that we see in the fall?

I am a certified chemistry teacher (grades 7-12) with 6.5 years of experience in the classroom. I have also taught freshman college chemistry. From these experiences, I have worked with a lot of different types of learners at various stages of interest and motivation- from high school students simply taking the class as a requirement to college freshmen chemistry majors passionate about the course with never ending questions. I can tailor my teaching style to fit the learner, and I do what I can to make it approachable by anyone.
This course also includes instructions (both pdf and video) for a hands-on lab activity where students can extract and separate the pigments from leaves through paper chromatography. This will require leaves, rubbing alcohol, a pencil, filter paper or plain white coffee filters, a glass, and a bowl.
學習者無需使用標準 Outschool 工具以外的任何應用程式或網站。
Students who wish to complete the hands-on experiment may need adult assistance.
