A place to share questions and comments about Science at ATA. In our monthly SINS (Science In the News) Students review a piece of media (newspaper, magazine, radio, T.V., Internet). Then share and discuss. Brief Synopses of our Labs will also be posted here. Feel free to comment! :-)

Hunter-Physics
I studied: How pressure affects the volume of a marshmallow, and Sound scope.
How Does Pressure Affect The Volume Of A Marshmallow: When one inhales through the straw, the pressure inside the jar decreases Causing the marshmallow to expand. The reason it expands is because the marshmallow is a spongy solid. when One stops inhaling through the straw it contracts back to original size.
What is a Sound-scope: The sound-scope is formed from a, balloon, rubber band(s), glue,sequin, flash light, and tin can (both sides punched out). When one talks into the can on the open side (the other being closed off by the balloon) it vibrates the balloon (with sequin glued on) making the image of the sequin on the wall move (made by the flash light).
Scouts in Engineering: For scouts in engineering this year I participated in a photography class. I learned about the different functions of cameras, Digital and Film. some of these things were.... What is a Flash: if there is not enough light in the room flash creates ambient (substitute) light. The advantages of a film camera compared to digital: You can expand the pictures size, 1 hour film prints, less expensive. What career options you have in photography: nature, architectural (that's a big one), sports, civil, culinary, model, and more.
ECHO Contraptions: My favorite contraption was the frog flipping the pancake. It was amazing how simple it really was. All it was made from was a crank handle, frying pan, stuffed toy frog, fake pancake, bike handle bars, and a odd gear. When one spins the handle it rotates the gear, while the pan is lowered closer to the floor. When one spins the crank far enough the gear disengages and the pan shoots up launching the pancake in the air and 99% of the time it lands back in the pan.
