Speed Mastery Quest Pt.2 (REGRADE)

Question: Which section of the graph represents the highest speed?

 Wrong Answer: The last section, where the time is 185 seconds to 200 seconds.

 Correct Answer: The first point of data in which the time is 20 seconds and the distance is 15 meters.

 Why: The reason the first point was correct is because you have to find the speed of each point, meaning you divide the distance by the time. If you do this you will get that Point A- 0.75, Point B- 0.5, Point C- 0.61, Point D- 0.53, Point E- 0.48,  and Point F- 0.5. Through this, you can see that the first point, Point A, clearly has the fastest speed.I got this problem wrong because I misinterpreted it. I thought it was asking for the greatest change in speed, but using the distance over time formula I was able to resolve this conflict.

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.

Image: www.flickr.com Summary: Throughout this week, the main topic of discussion was food waste and food systems. To understand the food system and how it works, we went through the system of apples and how they can be wasted in each step. The apples are produced and they can be wasted when they are eaten by insects. Due to this, they can't sell, so the farmers throw the apples away. Next, the apples are harvested. If apples have fallen on the ground or are not up to standard the farmers throw them away, even though they are perfectly fine. After that, the apples are washed and waxed to look appealing to customers. During this step, apples are wasted if the they are ruined while waxing. Some apples are then processed into different food items, such as pie filling, apple sauce and more. If people mess up during this conversion, the apple product gets thrown away. Then, the apples are packaged.If packaged incorrectly, the apples get thrown away. After this step, the apples ge...
