We've been learning that all matter has volume and mass. As a class we wanted to learn what ALL matter is made up of (whether or not it is a solid, liquid, or gas). We discussed atoms and molecules and how they are constantly moving in each state of matter.
In a solid they move more slowly because they are packed in close together.
In a liquid they move faster because they are less packed together.
In a gas they move very fast because they are spread far apart.
Next, we wanted to see what would happen if you mix a solid (baking soda) with a liquid (vinegar).
We quickly saw how if these two items are mixed, a chemical reaction happens and created carbon dioxide that filled the balloon with air making our gas. :)
I am not sure if you see Mr. Watchinski in the back photo bombing us - but he paid us a visit this day to observe Mrs. P. My students did such an awesome job (not surprisingly) and earned their last "Brownie point" and we enjoyed homemade brownies this past Friday to celebrate. :)
