Highlights from our last training:
We discussed triboelectricity and how rubbing materials transfer electric charges from one material to another. We started the experiment with a balloon and a towel. Rubbing the inflates balloon with the towel transfer charges to the balloon making it negatively charged. Then we saw how the balloons repelled each other and attracted to our skin which tends to be positively charged. Then we stuck the balloon on the wall to show attraction to naturally charged objects.
Second experiment showed the polarity of magnets by describing how it attracted and repelled. Concluding with the idea that “opposites attract”.
