Cladograms, cladograms, cladograms 10/22/17

Image: Pierre Kleinhouse Summary:  When we think of evolution we see monkeys magically turning into humans, but what is missing from that picture is the portion below it that makes it a cladogram. What is a cladogram? A cladogram is a diagram that shows the common characteristics of certain animals, as well as how closely related they may be. The top of the cladogram includes the organisms name and sometimes a picture. On the side of the cladogram, you will usually see different characteristics. Since a cladogram is drawn at a downward angle, the characteristic applies to everything above that point on the diagram. As you go up the cladogram, the animal at the top has all the characteristics listed throughout the cladogram. Along with this, the points in which two animals meet is not when they evolved from one another, but their common ancestor. Lastly, the diagonal line of a cladogram represents time.

Elements, Compounds, and Mixtures: 4/2/17

Image: Google Sites Summary: A pure substance is a sample of matter that has definite chemical properties. An element is a pure substance that cannot be separated. A compound is two or more different pure substances that are joined by chemical bonds. A mixture is two or more pure substances that are not chemically bonded. A heterogenous mixture is the least mixed mixture and is the easiest to take apart. An example or way to visualize this would be a salad. A homogeneous mixture, also known as a solution, can be separated by physical means. It appears the same throughout and is well mixed. A solution could be toothpaste or milk.  A colloid is when the particles are not dissolved, but they are mixed. Dissolving is not a chemical change. Fun fact, all living this are mixtures. S&EP- Conducting Investigations: We were transported to a castle built my the scientist Dmitri Mendeleev and we needed to get out. Each room was made of a different element in the periodic table....

Image: https://en.wikipedia.org/wiki/Geography_of_Arizona Summary: The project we completed was the biome project in which we had to create a text product, such as a trifold poster board, as well as a diorama of our biome. The biome that was assigned to my group was the desert and we decided to choose the Sonoran Desert located in Arizona. For this project we had to find edible plants and animals. To go with the plants and animals we had to describe them to prove that we would be able to locate them. In addition, we needed to know different sources of water, how and what materials you need to start a fire, and how and what you would use to build a shelter. Lastly, we had to know what hazardous organisms would pose a threat to us if we were in our biome. During this project, I not only learned about the Sonoran Desert, but some survival skills, too. Here is what I learned while working on the project: Plants: Fishhook Barrel Cactus Cacti are known to be in deserts a...
