Mirrors and Lenses Photo Project

In the picture above you can see that by using a converging lens I was able to light a piece of paper on fire, the converging lens bring the light rays together, and then the sun rays are refracted and concentrated at one spot. The light rays from the sun concentrated in the piece of paper then generate enough heat to make the paper catch on fire.

Molly and Pearl's Color Addition/Subtraction Photo

This photo shows the primary colors: red, blue, and green as well as the pigment colors: yellow, magenta, and cyan. All of theses colors are added together. The red and green make up yellow, the red and blue make up magenta and the green and blue makeup cyan. When red, green and blue lights shine on the white board, colors are being absorbed and reflected. The center of all the colors that are over lapping makes white because the red, green, and blue lights are being reflected.

This picture shows color addition because the cyan block absorbs the red and magenta block absorbs the green which make blue.

 

Color Addition/Subtraction

In the photo above there are two colors being added to create a new color. Yellow absorbs the blue lights, while Cyan absorbs the red lights. The only light that is left is the green one and that is the only light that shines through.

Pearl and Molly's 3-D Photo April 22, 2013

Molly and I took two different pictures of Gabby. At first we took a picture of her standing still, then we took a secondary picture that was a few inches off from the first photo. We then uploaded the photo onto the computer. We used the photo shop workshop on the computer. We uploaded both pictures and merged them and made one photo blue and the other red. The 3-D effect works using the colored filters (3-D glasses) because the colored filters separate 2 different images so each image only enters 1 eye. The blue and the red in the glasses overlap the colors. Our viewer has to focus on one thing and make the red and blue colors come together in order for it to become 3-D using the glasses.

3-D Peterson Project

We created this by taking two pictures of Andrew. We then changed the color filter and put them together, making a 3-D image. The 3-D effect works using the colored filters because when you put on the 3-D glasses, the colors overlap and make it stand out. In order for the viewer to see the image correctly, they would need a pair.

Dancing And Sticking Salt Mystery- Molly Carroll and Pearl

  

Claim: The salt sticks to the plastic tube becasue the tube is an insulator. The salt bounces off metal plate because the plate is a conductor.

Evidence: When the charged conductor (metal plate) is brought up to the salt the salt bounces off the metal plate and it doesn't stick to it. When the charged insulator (tube) is brought up to the salt the salt sticks to the tube.

 

Reasoning: The salt sticks to the tube becasue the tube is a charged insulator. The insulator is charged positively so that is why the nuetral salt sticks to it. The Salt bounces off the charged conductor becasue the charge is not evenly spread out around the whole surface of the metal plate. The Salt doesn't stick to the plate for long before it bounces right off .  

Toliet, Phone, Urinal, Laugh, Stairs - Caroline Serritella and Francisco Mendez

                      Our first example is a toilet. The decibel of the toliet is about 89.2 dBA.

                           Our second example is a urinal. The decibel was about 70.5 dBA.

Our third example is walking on stairs. It was actually louder than a urinal at 73 dBA.

Our fourth example was Jamie laughing. Her laugh was a decibel of about 94 dBA, which it pretty loud.

Our final example was a ringtone on an iPhone. That was the loudest, with a decibel of about 103.7 dBA.

We found out that the louder the sound gets, the higher the decibel. If there was a decibel of about 25 dBA, that could be compared to someone whispering, while if there was a decibel 100 dBA, it could compare to a jackhammer.
