Advanced Chemistry runs a Nuclear Reactor!!!

nuclear simulator game

Advanced Chemistry students ran a simulated nuclear reactor after learning about the events of Three Mile Island and Chernobyl.  They tried to keep the reactor running without melting down while maintaining a power output of at least 1000 kW.
5th hour Logan McDaniel won a smarty pants for his class, running the reactor for 259 days with an average output of 1256 kW.  Next was Bryce Markins with 232 days at 1246 kW.  Finally, John John Underwood had 159 days at 1037 kW.  Many students had difficulty keeping their power above the average 1000 kW which caused blackouts in their city.  Still others could not control their reactions and overheated, experienced a meltdown, and had to evacuate their town!!!!

Mrs. Lau's 7th Graders visit PCHS Lab!!!


Winning CARTESIAN DIVERS:  Karson (overall winner), Devyn, and Caitlyn
Chemistry Club students recently helped Mrs. Lau's 7th graders create Cartesian Divers that would sink and float to the top of a water-filled pop bottle when you squeeze the bottle. The concept demonstrate Boyle's Gas Law where increasing the pressure on a gas lowers its volume. It also shows how density affects the diver's bouyancy. Amazingly, you can use a Heinz ketchup packet as a diver as well! Here are the winners of the diver races and some pics of students making them in lab.
Jazzy Bennett and Chi Chi Whitacre help Brandon Shockley make a diver...

Mary-Hunter Smittkamp works with Zach and Dakota
 MorganWorrell and Kelsey Chambers perfect their divers....
Sarah Cochran works with Katie Smith before racing her diver!

Junior Logan McDaniel works with his diver team.

Tucker Marrs, Parker, and Garrett Clark team up with PCHS Chemistsry Club members Aleah Smith and Madeline Wilson.....



Mr. Pitcher and Mrs. Brading bring their 4th graders to work with PCHS Chemistry Club students....

Mr. Pitcher and Mrs. Brading brought their 4th hour classes over to watch and participate in several electrostatic and electronic activities.  They had just completed a unit on static electricity and circuits and the labs and demos help to reinforce those lessons.

Allison Hall has a hair-raising experience!

Cheyenne Miller shows off her static electricity!

Conner Land helps Ian Crouch, Colby Kindred, and Cole Myers set up circuits while Mrs. Brading looks on.....

Kagney Kingery sets up a simple circuit.

Mikela Washburn watches over Logan Rhoads and Tamya Hudson.

Payton Block entertains the class as she touches the VandeGraff machine!

Neila Volkman shows off her electrostatic skills!
