Just as the students get to be chefs and artist every week, they also get to be scientist every week in our classroom as well! We try to find experiments that match the themes of the week or the holiday and make it connect together. Before break it was Easter theme. Our budding scientist explored what happened to Peeps if you froze them, microwaved them, dissolved them in water and vinegar. And then they got to do their favorite part, eat the peeps!
For St. Patrick's day we had rainbow science experiments o' plenty! We made melting rainbows. This was a classic vinegar baking soda reaction mixed with food coloring and dish soap. The students got to add the vinegar to make the explosions of color. They were amazed. Did the understand acids and bases? No. But each student knew that the vinegar mixed with the baking soda to make a fizz. And they knew that the colors swirled together to make new ones. When the baking soda used up all the vinegar, it stopped fizzing. That is pretty smart!!! We also make liquid layers rainbow jar. The students thought this was so neat and understood that the liquid on the bottom was the "heaviest." If you want to see what we did there is a video of the experiment on youtube.
