In science, Spike is still working on simple and complex machines and Princess is studying solutions. They are both reaching the end of these study units. I am proud of how well they pick things up. Spike's science activity for the day was me giving him a list of things around the house to classify as simple or complex machines, and which type of machine they are. Some examples were the blinds, a doorknob, can opener, shovel, nail, and toy car. He took right off with the list and I only had to help him a little (he thought can opener consisted of a wedge and screw, instead of a wedge and wheel and axle).
Princess had an assignment on solubility and saturation. Her first experiment involved using a filter (a paper towel) over a cup. The solute was placed on the filter and water was poured over. She then analyzed what was left on the filter and what dissolved in the water to determine if things were insoluble, somewhat soluble, or completely soluble. The solutes we tried were sand, cornstarch, and sugar. This experiment did get a bit messy. Spike seemed to sense that and wanted to join in.
Princess's second experiment was about saturation of a solvent with a solute. She had a jar of 100 mL of hot water and kept adding sugar 1 tsp. (5 mL) at a time until the sugar would no longer dissolve. Princes thought this was a lot of fun....at first. She fizzled out, along with Spike. In fact, we were supposed to repeat the procedure with cold water, and then again with hot and cold water with salt as the solute.That was a no go, although they did seem to get the point of the exercise so it all works out. They did want to drink the ultra sugary water. I did let them, but only one sip...not the whole bottle. Spike said that there was enough stirring involved that it was quite a workout, and so he had to take off his shirt and just wear his undershirt. Silly kid.
