Barometers

Tuesday was Young Einstein Club again. For the older group we finished making our electroboards, discussed our scientific terms they had defined over the last week and a half, listened to an older child talk about the water cycle and then we made a barometer. To make the barometer we used a large (cleaned out) fruit can with cling wrap stretched over the top and secured with a rubber band. We put a straight pin through the end of a straw and taped it to the top of the can so that the pin end is hanging about 1/3 over the edge. The kids will be checking their barometer 3 times a day for a week.

With the younger group, we made rain gauges. We made them out of soda bottles and put markings up the side as measurments. We wrote some science words in their notebooks, listened to the same girl talk about the water cycle and then we made a cloud in a bottle. To make a cloud in a bottle we took an empty jar and filled it to the the top with hot water and put the lid back on and left it for 2 minutes. Them we removed the lid, poured 90% of the water out and put on a lid that was to big and that we had punched holes in. We put some ice cubes on top and let that sit for 3 minutes. After the time was up we removed the lid and ice and sprinkled chalk dust into the jar and reclosed the jar with the tight fitting lid (for 2 minutes). After the 2 minutes were up we looked at the jar at eye level and saw a cloud (it almost looked like fog). The kids had a lot of fun. When we were done with the experiment we talked about thermometers and how they work. We will not be having science class for another 4 weeks because of our baby that is about to be born! Try making a cloud in a jar--happy experimenting!
