This week we investigated batteries: how they work, how to measure their voltage, and what happens when you put them in series.
My original plan was to have them build circuits, but wouldn't you know it...all my AAs were dead. Pretty embarrassing the first week and all! Luckily I had just gone grocery shopping and had plenty of lemons and potatoes, and the fruit on my grapefruit tree are ripe.
Why was this lucky? No, I did not distract them with lemonade and french fries ... it turns out that with a few strips of copper and zinc, wires, and various produce, you can light an LED.
Your kids are now ready to guest-star on any of McGyver, Lost, or Gilligan's Island.

Physics: Quizshow Pt. II
This week the kids finished their quizboards - hopefully by now you've see them, played them, and hopefully not broken them!
This was NOT an easy project. It took a lot of patience and attention to detail, checking and rechecking connections in the circuits, but in the end it paid off. "Operation's" got nothing on these quizboards.
I've posted this week's quiz. http://www.scienceinmotion.co.il/blog/
Please encourage your kids to take the quiz and not to forget to sign in at the end. No, you won't be inundated with spam as a result. Signing in just allows me to track their scores, so they can get prizes. What are the prizes? Something between a taffy and a trip to Hawaii.
If you haven't already, please register your kids and send in checks next week. Those kids who aren't fully registered by next week will have to work off their debt at the Large Hadron Collider where they will be forced to collide opposing beams of protons (one of several types of hadrons) with very high kinetic energy in order to explore the validity and limitations of the Standard Model, the current theoretical picture for particle physics.
Have a great week!

Physics: Quizshow!
This week the kids started to build quizboards.
What's a quizboard? A quizboard is a game in which you try to match up questions with the correct answers. If you succeed, a light bulb turns on, and if you get the question wrong, nothing happens. Interestingly, all my groups, without exception, wanted to add features to the quizboard that would punish players with a beep or even a shock for wrong answers. Needless to say, we went with the simpler design. Anyway, psych experiments aside, the kids had a great time, and next week they'll be finishing up and bringing their quizboards home.
