Image: Khan Academy Summary:  If you were walking down the street and turned right, did you accelerate? While most people would say no, change in direction is, in fact, a form of acceleration. Acceleration doesn't just mean increasing speed, it is change in velocity. The formula for acceleration is change in velocity divided by time and it is measured in units of distance units of time squared. An example of this would be 60 meters per second squared. Acceleration is a vector quantity because direction plays a factor in acceleration. (Vector quantities are measured as magnitude with direction.) Like mentioned before, people assume acceleration has an association with the term 'speeding up' although this is not the complete definition. Even slowing down is considered acceleration, although more often than not it is referred to as deceleration. S&EP-Using Mathematics: When people think of science, most people see lab work and experiments, but lately, through...

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.

Image:  Summary:  Speed is so called, a distance over time, but what actually is speed and what does it have to dow ith velocity? Speed is a scalar quantity, whereas velocity is a vector quantity meaning speed just measures "How fast?" whereas velocity measures "How fast?" with direction. An example of speed is 60 mph, while an example of velocity would be 60 mph north. It is important to know the velocity, as well as speed because if not, it could create a conflict. For instance, if a missile is flying at 7,500 mph and you do not know which way it is going it could possibly hit you. Although this is a far-fetched example not knowing velocity could create conflict in the simplest environments like a street corner. All in all, speed and velocity aren't that different, but the difference is key because it is what makes one a scalar quantity and the other a vector. Fun Fact: You can use graphs to determine speed using rise over r...

Image : The Science Classroom Summary:  A scalar quantity measures the magnitude of something, whereas a vector quantity measures both the magnitude and the direction. Magnitude doesn't have to do with speed, it is just a number that measures something. For example; How big? How far? How fast? An example of a scalar quantity would be 60 mph, while a vector quantity would be 60 mph east. Speed is a scalar quantity, whereas velocity is a vector quantity. It is important to know the velocity, as well as speed because if not, it could create a conflict. Another way to measure motion is to use reference points. You can tell if something is moving if its position changes in relation to a stagnant or non-moving reference point. An example of this would be using a tree as a reference point because it doesn't move. If the distance between something and the tree were to change the object is moving.

Image: Summary: What is human trafficking? Well, it is modern day slavery in which men, women and especially children are exploited through force, fraud, and threatening. It occurs around the world, including right here in the USA. Victims are trapped, vulnerable and unable to take action without risking their own lives. World of Children is “unlocking the future for vulnerable children by funding and elevating the most effective changemakers for children worldwide.” World of Children’s Honorees are working to rescue and rehabilitate victims of child trafficking so that they are safe, supported, and have the opportunity to rebuild. This charity has been around for 9 years and they have raised a lot of money. According to World of Children Charities, they have made a total income of $1,916,334, from public funds, restricted and unrestricted boards of gifts, and in-kind donations. “Contributions from our Board of Governors pays for 100% of general and administrative costs and...

              De-extinction in the process of "resurrecting" species that have previously died off through cloning, selective breeding, and DNA splicing. Scientists are working to rack in an immense amount of money to perform de-extinction on animals like the woolly mammoth and the passenger pigeon. The science behind de-extinction is groundbreaking, but with environmental conditions depleting we should focus that money towards preserving species that are still alive today.      Scientists cannot perfectly predict how each and every animal that is resurrected will act. Species that are de-extinct have the complete possibility of being the top predator and wiping out other species, or they could overpopulate because other species don’t have the system to consume it. As well as that, if scientists can de-extinct species humans will care less and less about the environment and continue to destroy it because if an animal dies we can j...

Scientists are working to rack in an immense amount of money to perform de-extinction on animals like the woolly mammoth. They claim the woolly mammoth would actually be helping the tundra, due to the fact that ice is melting and the soil contains carbon which would release if more ice melts. The woolly mammoth would “punch down the snow in the winter time allowing cold air to come in and in the summertime they would knock down trees which are very absorbent and release the grasses,” said Steph Yin in  We Might Soon Resurrect Extinct Species. Is It Worth the Cost?.  Along with the wooly mammoth, many scientists are considering the resurrection of the passenger pigeon. This particular pigeon allowed regeneration in certain forests by fra...
