Cold and Science Fair

The cold weather is gone, thankfully. It was 60° today. But it did get colder than they forecasted Tuesday morning. -2°


Thankfully no pipes froze and the cars still started.

Tonight Lauren’s class of 12 students had their science fair. The judges were all science teachers or former science teachers at the high school or college level. The kids had to present and then answer questions about their experiments. One girl we know won the blue ribbon.


She made markers out of dye from fruits (strawberries, cranberries, raspberries, and pomegranates) and measured the hue and intensity of the colors and compared them to a red Crayola marker. Besides the marker, cranberries had the most intense red color. It was a fun evening with lots of neat projects from a homemade glockenspiel to toilet bowl cleaners to typing tests with and without caffeine to cooking hotdogs in a parabola. We are very proud of all of her hard work.

    Congratulations! What a neat project. I would like to try some of those dyes sometime.
    Love, Sheri

      We had a hard time finding pure cotton cording to make the markers. Therefore that was one of the drawbacks. They did not write very dark. But Lauren explained all the “flaws” in her experiments and one of the judges said that was one of her strong points. She knew all the weaknesses and was very thorough in explaining the uncontrolled variables.

    What a clever idea! I bet they smelled good too!
