  Evolution ~Descent With Modification Hillary Clark The history of all life is explained by evolution. Charles Darwin’s (right) book, “On the Origin of Species”, states that evolution is “the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.” In other words, evolution is descent with modification. There are two main points that explain descent with modification. First of the two says that all life on Earth is connected and related to each other. Second says that diversity of life comes from modifications in populations driven by natural selection. Natural selection is a huge part of evolution. Survival of the fittest shows one way natural selection helps evolution. Survival of the Charles Darwin fittest is an organism's ability to survive and...

Density Hillary Clark 10/6/17 P4 What is Density?   Have you ever wondered why water and oil don’t mix? The oil always floats to the top, and density is the reason why. Because oil is less dense than water, they will not mix. Density is the ratio of the mass of an object to its volume. In other words, density is the amount of stuff (atoms,molecules,etc.) in a fraction of matter.   How to Find Density                                          To find the density of an object, you first need to know the things mass and volume.Then, you divide the object’s mass by its volume to find the density. Mass is measured in grams (g), and volume is measured in cubic centimeters (cc), or centimeters cubed (cm3) . When you find the density after dividing, you must label your a...

Hobbies     One of my hobbies is playing ukulele. In the picture below, you’ll see my  ukulele. A ukulele is like a small guitar of origin in Hawaii in the 1900s.  There are different size ukes , like shown in the picture below.  There are also different parts of a ukulele , as shown below. To play the ukulele, I have a pick (shown below) that I use to play so I don’t hurt my fingers over time. There is also a tuner, that helps me tune my ukulele before I play so the sounds are played correctly and not off. (Shown below) .
