Ask Dr. Joe
Greetings to students of Wilson Creek Elementary School! Have you ever wondered why the sky is blue? Or how a television screen works? My name is Professor Joe Checkelsky and I am a scientist at MIT where we spend all day thinking about these kind of questions. My hometown is in Fulton County and I want to hear what students there are wondering about. Click here to go to the Checkelsky website and see the winners and the answer's to our "Ask Dr. Joe" contest.
Congratulations to Angelika a student in Ms. Marcuses 3rd grade class for winning the Ask Dr. Joe question. Angelika wanted to know "Can you freeze a bubble without popping it?" To see the answer go to:

This month, Angelika asked if it is possible to freeze bubbles. It turns out, the answer is yes! To understand why this is possible, we need to learn about bubbles and what it means for something to freeze.
To start, let’s look at what a bubble is made out of:
Part 1: What is a bubble?
Next, let’s look at what it means for something to freeze:
Part 2: What happens when something freezes?
Finally, let’s see how to freeze the water inside of a bubble!
Part 3: Frozen Bubbles
