Understanding Phase Changes and Activities

Andre O'Brien from Lucilla Brown Middle School presents a physical science lesson focused on phase changes. The lesson is structured over three days, with Day 1 dedicated to engaging and exploring through videos. Students are encouraged to reflect on questions about boiling, freezing, and molecular changes. The lesson includes four videos demonstrating phenomena like supercooled water and dry ice sublimation. A hands-on activity is also provided to explore freezing rates. The session concludes with a preview of Day 2, which will involve reviewing videos, vocabulary, and additional activities.

What is the main focus of this week's science lesson?

• Phase changes

• To write down questions for the teacher

• To record video timestamps

What should you do if you want to rewatch the first video?

• Wait for the teacher to replay it

• Ask a classmate to explain it

• Skip to the next video

• Use the link provided on the sheet

What phenomenon is shown in the third video?

• Water boiling
