Open and Closed Systems were introduced in class today. We wrote and drew examples relating to the concept (open water bottle/closed water bottle). Also we discussed whether Earth is an open or closed system. We determined that Earth was a mostly closed system because very rarely does matter enter or exit it.

We read page 32 in our giant textbooks today.

The students did one Socrative question, too.
