Kitchen Chemistry

These are center activities for a 2 week unit on Kitchen Chemistry. Hands-on activities are adapted from suggestions in Steve Spangler's book, "Naked Eggs And Flying Potatoes Book: Unforgettable Experiments That Make Science Fun!" QR Codes linked to each center (to print as center signs) are available as a Google Doc. The PDF file I'm using to manage student groups and daily center assignments is also available via Google Drive.

There are 8 center activities for this unit. 5 of the activities are hands-on labs, and 3 are videos. For each center, students will post a reflection to their blog or to our class AudioBoo account. On day 2 of this unit (because of a teacher absence) students are watching Geek Week - The Spangler Effect LIVE! from August 6, 2013 on YouTube.
