electric station assignment REFLECTION!!!!!!!!!!!

We did an electron lab station assignment with 4 stations to learn about electrons and what they attract/repel to.

First station: This station had a balloon were you generated static on the balloon and we had to find out if we generated enough static on the balloon too attract confetti to the balloon.
One of our observations were that it took a lot of static to attract the big sheet of confetti but less to attract the small confetti. My hypothesis before was that it would attract the confetti and the really big sheet of confetti so i was right all along and so was my group. This station was something i already knew so it was pretty much old stuff but it was alright.

Second station: This station was about Cutting off two pieces of tape and try to put the un sticky sides together to see if they would attract or reppel and they attracted to eachother we observed that we also messed up because the two tape pieces attracted together so much that the sticky sides stuck to eachother and we were like WHOAH!. I hyphothesised that they would attract.

Third station: This station was basically the same as the second one but this time we attracted only one un sticky side to the sticky side and they attracted to eachother also, one of the observations we made that it was hard to like see how they attracted but they attracted to eachother pretty fast. On this station i hypothesised they would also attract and my group agreed with me i do onot have any questions for this lab .

Fourth station: This station was about charging the balloon with electrons and put it next to running water and see if it attracted or repeled when my group first tried it me and my homie saw that the water repeled and my group "leader" said "no it didnt" and we rubbed the balloon on my homies head and he was like owww! and he put it next to the running water and it attracted like crazy and we like OHHH SHNITWHIZTER! this station was my favorite one because it was pretty cool that the water was attracted to that balloon i predicted that it would do nothing but apparently it attracted pretty cool lab though.
