We took a break from our regular "project" Saturdays to squeeze in some holiday activities. This week, however, we decided that it was time to get back to our extra-curricular activites. The first experiment we did was to make a lava jar. The kids really enjoyed watching this, as well as putting it together. We filled a jar 3/4 full of water and then added some oil. Next we dropped some (well, lots!) of food coloring in. To get the real party started, we added bits of an Alka-Seltzer tablet. The reaction was fun to watch.
In the second picture, we made mini volcanos. The kids poured baking soda onto a cookie sheet and then dropped some (well, lots!) of food coloring on the peaks. Then, with a small syringe, they squirted vinegar on the piles. The reaction was quite fun to observe. I think they could have kept doing this for hours.
We also made home made play-doh. Since it was such a nice day, we ventured outside (47 degrees, sunny) later in the morning. I will post more photos of this tomorrow, since I am having problems loading photos onto the blog.
