Science Experiments!

On the bucket list for summer, Kevin added science experiments. What he had in mind was explosions, but I can not do more than Mentos in Diet Coke. In response to his request, I am signing both Colin and Kevin up for the St. Louis Science Center science classes at the library. (They are free, and have one on robotics and one on explosions!)

In the meantime, I did two experiments that I was ready for with no prep at all. The first was a chemical reaction involving salt, vinegar, and pennies. The boys made some predictions, and one guessed that the pennies would be clean. Not super exciting, but anything science has a certain interest level.

The second one involved food coloring and celery. (I usually have celery on hand since I like them in my salads.) The boys filled the glasses, made predictions, added the color to two glasses, and of course Kevin put those predictions on a chart. I always have a control, so the third glass is normal water. We only did food coloring, but I am thinking on boring days we will redo the experiment, and add sugar and salt to other glasses to see what happens. (If you caught that, I implied that these experiments will make the day LESS boring.) I love my kids.

 

 When we left for vacation, the leaves had some color in them. It was neat to see the celery with so much color when we returned. Also, we trimmed the red celery and the control celery. I noticed that those glasses had less water after a week. Interesting.... SCIENCE!
