Welcome Back! Introducing the Black Box...

Welcome back to school, chemists!

I know I had a great summer working on some curriculum projects and spending time with my family.

In chemistry we are diving right in to scientific experimentation and the nature of the atom. We did a class activity where we explored what was inside of a "Black Box" through indirect experimentation. We did this to model the process that scientists go through when trying to discover the nature of things that are too small to see, touch, and otherwise observe directly.

In period 3 we first tried pouring 99 mL of water into the Black Box and were very surprised when only about 85 mL of a bluish-green, odorless liquid came out!

We then tried adding 99 mL of vinegar into the Black Box and were even more surprised when 88 mL of a brighter green, vinegar-smelling liquid came out!

What do YOU think is inside the Black Box? Below are some of our drawings of what we think might be inside.
