We had another wonderful year at the Calvert County Science and Engineering Expo at Calvert High School. They do a fantastic job putting this on every year. There are so many activities you can’t even do them all in the four hours the expo lasts. Plus it’s wonderful for the littler kids to see all the high schoolers enthusiastic about their various fields of study. One of Harlan’s first activities was driving some remote controlled… things… Even Elise got to fly a little drone. The young lady running the table was completely unphased at her age (or maybe she saw the “genius” shirt and knew she could handle it). They did a number of little science experiments like extracting DNA from a strawberry and blowing up a balloon with the carbon dioxide produced from mixing vinegar and baking soda. Harlan also put on some gloves and touched various cow innards from eyeballs to the heart (I’m sure Elise would have too but she was exhausted by then with no nap). They both made aluminum foil boats and loaded up marbles (Elise dropping them in by the handful from about 7 inches up- not the best technique if you want your boat to stay afloat), and Harlan built a little catapult and shot paper balls at a target (Elise had a great time dodging the shots and collecting all the paper wads). We all had a fantastic time, and are already looking forward to next year.
And a movie:
