Oreo Cookie Tower for Chemistry I

A smarty pants challenge was presented to the Chemistry I classes when learning significant digit rules.  One of the rules is commonly referred to as the "sandwich" rule where zeros are counted as significant figures when placed between non-zero digits.  Even if there are more than one zero, the zeros count and it is much like a double-stuffed oreo, which led to the challenge of making artwork or a tower with oreos.  Here are some of the winners of the challenge:  Johnna Sanchez and Kylee Marietta made a video of there tower, but I do not have a picture...


Caroline Heath wins with the highest tower of 47 oreos!  The world record for single stack without a base for support is 48 oreos held by a Canadian guy.




Maddison Plummer and Christian Villefrance made a single stack oreo tower of 43 oreos!

Maddison Plummer is excited.  It is harder than it looks! 



Sam Groves had the artistry award this year.


Kaitlin Block and Lea deBoer won last year in that category.

AP Chemistry Makes Esters!!!

Students worked this week on making sweet smelling esters from a carboxylic acid and an alcohol.  Sulfuric acid was used to dehydrate the water that was also produced and a hot water bath was used as a catalyst.





Cartesian Diver Lab 3rd hour Advanced Chemistry

In this lab, students created several Cartesian divers to study Boyle's Law, relating pressure and volume of a gas.  These divers sink and rise in a closed bottle of water by changing the density and altering the buoyancy.  Students raced their divers with others to choose a representative for their hour and race to win a smarty pants!!!  Jeffery Martin won for 8th hour and beat Danny Allanson's awesome diver of 3rd hour diver to win a smarty pants!

Danny races his diver with Sydney...

Hey Jeffery!  Hey what?  It's your birthday!













Energy of Foods Lab 7th hour Chemistry I

Chemistry I students recently looked at the carbohydrate sugar glucose in the form of a marshmallow and compared it with the linoleic acid fat in the form of a tostito chip, cheeto, and peanut to see which molecule takes more energy to form and which one gives off more energy when burned.  Students created their own apparatus to hold the food below a pop can filled with water to measure the heat from the food and capture it into the can.  After many trials, student improved their apparatus to include a chimney to maximize the amount of heat flow.  Their designs and measurement skills vastly improved over the four day lab.  Here are some pics!
