If you missed today:
1. Make sure you pick up an empty 35mm black film canister and lid that can hold a pressure. Also, request an alka-seltzer tablet to practice at home with. When at home practice by trial and error adding drops of water off your finger and a fraction of your tablet until you can get the lid to blow off in between 20 and 40 seconds as your goal is exactly 30 seconds for the most extra credit.
Bring your empty film canister and lid back to the classroom next Friday for 5 pts. out of 5 pts. and for the opportunity to get two trials to obtain extra credit.
2. We watched a video clip from Home Alone 2 and students recorded at least 18 instances of where P.E. or K.E. or Work was witnessed. Example: Boy did work to lift a brick, brick was high on the roof so had a lot of potential energy with the road below as ground zero, K.E. increased as the brick fell and was maximum as it hit the crook in the forehead,....
3. We did a demo showing a sad ball boiled became a happy ball and a happy ball cooled in ice water because a lot less happy (lower coefficient of restitution). Mr. Konichek tells the story of the Challenger disaster caused by o-ring's changing their characteristics on that cold morning... The story continues when Mr. Konichek is hired by NASA to represent all the high school teachers in the nation to be on a panel of k-16 professional educators to write the criteria that was used to help choose the next two teachers to be trained to be Astronauts.
4. Mr. K. did another demonstration on the teachers desk to prove one wants to make the souls of tennis shoes out of sad ball material by swinging a happy ball and then a sad ball (from the same height) into a small board standing at the base of the swing (where the Kinetic Energy is the greatest). The happy ball knocked it over.
Here are some of Mr. Jenkins notes that were used to help understand Coefficient of Restitution (a billion dollar business). Coefficient of Restitution Data Coefficient of Restitution sample lab
5. Students took turns laying on a bed of nails. Enjoy the videos of Physics students having a blast. Thank You Mr. Weidner for passing on such a great program!!! Mr. W. built the bed of nails and most of the other cool things we do throughout this course. Mr. Wright and Mr. Jenkins were also catalyst in making and keeping this Physics program going. Mr. Hagstrom build a ton of his own Physics demos of which he let me use his bed of nails today that had density of at least 50% more nails so felt as good as ones bed at home. Spread the word students, that Mr. Hagstrom plans on maintaining this exciting program after I retire.

In 2013-2014 many students showed they Trusted the Physics by laying on a bed of nails.
The winning smiler for laying on the bed of nails for the day and placed first is Kara.
Tylan, Dom, and Grace
Neil, Erik, and Brianna take turns laying down on the job.
Willy shows what being on the SPASH swim team can do for your abs!
The fearsome four of Shue, Derek, Luke, and Kaitlyn enjoy acupuncture.
Bailey was the first this period to mention someone standing on the abs of another.
Andrew, Heidi, and Alex caught on a bed of nails.
What Marc is willing to do for the sake of science AND Maria shows she has what it takes. (Johnny visits, always great to see you Johnny!)(Bring T-Bone with you next time...)
Kelly volunteers 1st her period and shows everyone how it is done.
Tousen lets John stand on his abs, then John lays down on the sharp bed of nails with the thinnest of shirts on.
Andy stands on Dylan's abs.
Joe models how it is done.
Kiara shows her bravery, with a smile, on a daily basis in Physics class.
Last but not least, my true superhero this school year, Jack. You are so much braver than I was at your age (Jack was one of the Mr. SPASH candidates last fall.)
The material below is from 2012-2013 school year.

4. We did a demo showing that a force pushing an object through a longer pipe gives the object more Kinetic Energy by blowing a marble through three different length pipes.
5. We did a demonstration showing an implosion instead of an explosion.
