                Students in freshman Earth and Space classes have been learning about the Earth. They collected data from an experiment testing heating and cooling systems that they completed.
In the experiment students are given soil, sand, water and salt in a cup.  Students then stacked books on top of chairs and placed a meter stick over top.  Finally they were given a thermometer and a heating lamp.
Students then had to write a hypothesis of which substance they thought would warm up fastest and which would cool off the fastest.
Students set up the experiment and every two minutes they recorded the temperature of the different substances.  After twelve minutes students then shut off the light and kept track of the temperatures as they cooled.
Once all of the data was collected, students shared their different temperatures with the teacher and the rest of their classmates.
They were then given a piece of graph paper, and told what to label the X and Y axis and also what to label each side. The teacher also did the math work for them and helped them figure out how much each line should go up by.
Finally, students used different colors to graph all the data they collected and turned in the lab assignments.

Kaelee Kessee Managing Editor                  In social studies Eric Gross’s AP Human Geography class, students have been learning the skill of answering essay questions that will be seen on the AP tests this May.                 The questions are known as Free Response Questions or FRQs for short. The questions are centered on the material learned in the class throughout the semester. The most recent FRQ pertained to the information learned in the second unit of the book over population and migration.                 The students had the opportunity to take their first FRQs home to work on them overnight.                 “I thought that for the first one it would be good to do a take home assignment to gently get [them] into it. Next we’ll be doing one in class and eventually as a test,” said Gross.                 When grading the tests, Gross looks at the responses the way any AP grader would when looking at them this summer.                 “I look for: Did you answ

Demi Muchmore Editor in Chief                 Notice the sticky notes on all the lockers as you’re walking in the hallway to class? You have Stand For The Silent members to thank for that. These aren’t just ordinary sticky notes, on every single sticky note there is an inspirational quote to start your day.                 During spring break, students that are a part of stand for the silent got together and made a sticky note for every single locker in this school. Mrs. Goodrich is in charge of this club and actually came up with the idea. “We did it to uplift people after coming back from break,” sophomore Cassidy Oberbroeckling said.                 When asking other students what they thought of the idea, they responded with positive feedback. “It was a very good idea and it was cool to walk around and see all of the different messages,” senior Nic Henderson said.                 Doing these creative messages can really help to brighten a student’s day after everyone
