More Cool Science

This week we made and tested motor boats in science. We tried to make the boats go faster and carry more weights. Orange group carried 36 rubber erasers in their little boat! That was the record for the class.

We also did electrical circuits:
  • complete/simple
  • closed and open
  • series
  • parallel 
The coolest series circuit had 12 light bulbs, 11 batteries, and 13 wires. When we got done assembling it and it lit up, the class burst into "Jingle Bells."

The coolest parallel circuit was very bright. If one bulb got unscrewed the other stayed lit.

Another thing we did in science was spinner art using a little motor and 3x5 cards. We observed what blocks of colors looked like when they were spun together. Red, yellow and blue made a light pink like a kind of medicine. Red and blue made a magenta. Pink, green, and orange made orange with a purple outline. Light blue on the edges looked clear almost when it spun.

    From Education Week--According to the latest research, the two best predictors of college success are not grades and intellectual ability. Number one is “conscientiousness” (dependability, perseverance, work ethic). Number two is “agreeableness” (interpersonal skills, getting along with other people, working well in groups).

    From what I’ve observed, I would say the same is true for life after college—jobs and careers, marriage and family life. Success comes more easily for people who are willing to work hard and who are able to cooperate with other people.
