Hi,
  This week you will be designing and doing a controlled experiment on Tuesday.  You will be investigating which of several substances makes an ice cube melt the fastest.  You will then take your data and write up your results.  I will explain how to do this in class on Thursday.  You will have class time on Thursday and Friday to work on this.

Due dates:
• Rough draft of ice lab write-up by end of class - Friday 19 Sept.
• Ice Melting lab write-up final due - Friday 26 Sept.
