Today we talked about bobcats - the wild animals, not the students - in class. Several students wondered if it is legal to hunt bobcats. It is, and the regulations aren't as strict as I thought they would be. They are classified as a non-game animal. You can find out more at this link: Texas Non-Game Hunting Regulations.
 
The first week of school we practiced making and recording observations. Observations led to questions: We observed how the color from Skittles candy spread into water. We wondered "What if we moved the skittles around?"; "What if we used different colors of skittles?"

Here's a little bit of an explanation:
The color from the Skittles is made of a food coloring chemical that spread into the water. That chemical is made of tiny particles called molecules. The molecules spread into and through the water. That's called diffusion. The molecules then completely mixed up with the water. That's called dissolving. It made the water the color of the food coloring. When water of two colors hit each other, they affected each other. One color may have been "heavier" and slid underneath; the other may have been lighter and slid on top.

Try this at home:
Which is heavier, water with red coloring from Skittles or water with yellow coloring?
Do you get the same results if you use red and yellow from other candies? What about using red and yellow food coloring?
