After losing the seniors, we worked on a neat lab that I used to use when teaching meteorology. I used it to show how warm and cold air met along a frontal boundary. I used it today to reinforce how ocean water density is affected by temperature. The students loved the lab. Lots of Snapchat videos and photos of the warm water sliding over the sinking cold water and smiling students. They replaced the divider and then mixed one side to create warm purple water. They were so interested to see what happened when the divider was removed and were amazed when it wedged between the red and blue water.
Graduation is on 5/29 and today (5/27) was the last full day for seniors. We are one of the few places where the students get their senior prank approved by the administration. Last year the Class of 2013 parked two cars in the lobby and surrounded them by 2013 cups of water. This year they plastic wrapped the breezeway, and strung string across the walkway. Some seniors grilled in the parking lot at lunch. Good kids!
IS II students determined the salinity of a sample using evaporation. Clearly this is not a great method but it is good for them to practice a procedure and they better understand the concept of salinity in parts per thousand (S o/oo). They are able to calculate experimental error and discuss the reasons for it. The samples are placed in a drying oven overnight.
Not a busy day as most of the senior stayed home. Saturday was the prom and the post prom ended at 6 am on Sunday. We knew today was a planned skip day. Ironically, they senior quilt is on display. We had one building for K-1 for many years and the teachers put together a quilt made of 200 student drawn images done when the kids were in 1st grade. It is heartwarming to see how innocent they used to be and how universal the drawing seem to be. My favorite the one by Ryan who clearly remembered his planetarium visit!
Physics I and AP Physics build cardboard boats to race in our pool as a culminating project for their unit on buoyancy. In true performance based grading, the boats must make it the length of the pull to earn the top scores. This year more than in the past the students really got creative with the themes.
Today I took 5 (of the nicest students) student council members to Hershey PA to tour the PSU-Hershey Medical Center and meet with the Four Diamonds staff. The photo is taken on the 3rd floor of the new children’s hospital. They have a roof garden so patients can get outside easily. We toured the labs and the patient floor and even met with a courageous 18 year old who has been battling cancer for six years. What an inspiration she was! We have renewed enthusiasm for miniTHON 2015 and have a better idea where the money goes and what we support. It was an uplifting day.
The end is coming soon. Seniors graduate on May 29th and only have 8 class periods left. Because of the snow days (9 of them!) the underclassmen have until June 6. I have to give a final to classes that have juniors and seniors on May 21st. Not much in terms of a photo for 5/14 so here are two images at the front of my room. The photo on the right is my first grade school picture, a nice reminder that we all have that in common!
