Parallax is when  there is apparent displacement  of an object because of a change in the point of view. scientists use this method to measure the distance between stars. As the earth orbits around the sun the closest stars appear to move backgrounds amongst other stars. Scientists measure the star once and then six months later. After they take the data and measure the difference.

In this experiment, I had to make a model of a DNA using liquorice, different coloured marshmallows, and toothpicks.  The liquorice represents the double helix. The backbones of the DNA are made up of sugar and phosphate. The different coloured marshmallows in the photo represents the bases which are adenine (yellow marshmallow), thymine (orange marshmallow), guanine (green marshmallow), and cytosine (pink marshmallow). The rungs or base are always bonded in a certain way, adenine (A) double bonds with thymine (T) and cytosine (C) triple bonds with guanine (G). This activity gave me a better understanding of DNA. Matching the bases helped me remember their names, letters, and also their pairings and also gave me a general idea of what DNA looks like.

I had to make a DNA bracelet.  Each coloured cereal represents a combined base letter to make it into a codon. Green = adenine, purple= guanine, yellow = thymine, and pink = cytosine. The 3 pieces of cereal makes it a letter in the alphabet of the DNA alias code. The entire message of the bracelet represents the DNA sequence. My name is representing the multiple codons which make up amino acids.
