Science Sunday: Density of Gases

We are using one of our favorite items at the Science Center (dry ice)  to talk about the density of different gases. Simply, dry ice is solid carbon dioxide and when we add hot water to it, we release that carbon dioxide gas. So what happens when we compare the carbon dioxide gas released by …

Science Sunday: Polymers

We have talked about polymers before on Science Sunday, can you remember what they were? That’s right! One of our favorite things here at the Science Center, slime, is a polymer. There are so many other polymers that you can find in your everyday life, including a plastic bag. We are doing a fun experiment …
