Science: The Great Race
The vehicle that I have designed and built was made out of a paper towel roll for the base, bottle caps for the wheels, metal hangers for the axil, and lastly, duct tape for extra support. First of all, I covered the wheels with smooth tape to reduce friction. I also added stones inside or "passengers" for extra mass. The extra mass would help the car expedite down the ramp. My car is an example of Newtons's Second Laws of Motion because my car uses the formula force = mass times acceleration. In this case, the force is created by the mass which is the stones and the acceleration, which is the push before it rolls down the ramp. Therefore, it describes the second law the best.

Literature: 5 Fables
The first fable is called The Wolf in Sheeps Clothes. It is about a wolf who tricked the lamb by leading the lamb away from the sheep and eating them. The maxim of this story is that looks can be deceiving. The second fable is The Four Oxen and the Lion. The moral is that there is power in numbers. When the four oxen were together, the lion couldn't eat them. But when they were seperated, they were less powerful and lion could eat them. Next, was The Fisher and the Little Fish. The maxim is even a little bit is good. The Crow and The Pitcher comes next. The moral of this is that nothing is impossible because the crow found a way to get water. The last fable is The Fox and the Goat. The moral is that don't trust everybody.

Literature: Wooden Bowls
The story of "Wooden Bowls" was very unique and therefore I liked it a lot. The moral of the story is that "you get back what you give." That is because at first the boys parents treat the old man without any respect and leave him alone in the corner. But when they realize that the boy was planning to do the same with them, their thought process completely changes because, they know that what they were doing would be given to them too some day by their child. This relates to C.A.R.E.S with empathy since the meaning of that is to put yourself into the other person's shoe, which is exactly what the parents did. In a way, I can also relate to this because I have seen this happen to some of the elders I know. But, in the end, similiar to the story, their kids have learned their lesson too.

Science: Ask a Geneticist
According to the facts of these geneticists, I have learned a lot. One of the most interesting genetics facts that I have learned about is that why humans have more or fewer genes than chimps. The answer to that is that both started off with the same mumber of chromosomes 5 million years ago. But then the two started to drift apart in evolution causing their genomes to change. Some sections of that were lost, gained and copied. The chromosome also fused together or broke apart so that 2 human chromosomes were similiar to 2 smaller ones of a chimp. The genome that code for genes only differ by 1.2% saying that they are 98.8% the same. Another cause to the difference is the amount of protien that reaches the brain. All these reasons help better understant this topic.
