Seashells
Watch this and read this. What are seashells made of?
Mix calcium chloride with sodium carbonate. What happens?

What is Precipitation?
Learn why some things form solids when you mix them. 

Precipitation Lab
***DO NOT POUR ANYTHING DOWN THE DRAIN. IT'S LIKE A $20K FINE***
Mix together the different solutions in a well plate to figure out what is in the mystery solution. You will need to think about a strategy. You can use the whiteboards to make notes. 

Crosscutting Concepts
What Habits of Mind did you use to figure out the mystery solution? 
In our science standards we call these crosscutting concepts.
