Videos on Demographic Transitions

Khan Academy:
  • Demographic transition states that the population will eventually stop growing
  • To find growth rate you count how many people have been added to the population and how many people have been removed from the population
  • High birth rates usually have to do with the fact of limited birth control
Kim Smith:
  • From the agricultural revolution to the industrial revolution the population of the world only grew by 67,000 people a year
  • Now our population grows that much every 67 hours
  • In the olden days a women's status was defined by how many children they had & children were defined as assets
Why Populations Grow:
  • Some countries have negative population growth
  • A way to measure population growth is the doubling time- the length of time it takes for population to double in size
  • Natural increase and net migration are the two main factors that influence population change

In my opinion the Khan Academy video was the most helpful because it described demographic transition the best and gave good examples which made the topic easier to understand. It also had a visual which helped me to actually see what it meant and the numerical aspect of the topic.

Cyber school

Today you asked us to write about our thoughts of what you posted on your blog today about the struggles that everyone is facing regarding cyber school. For me, this is something I think about a lot. The main topic that I worry about is the integrity part. I have found myself multiple times talking to people in my class on the phone and trying to understand the material and then realize that I am probably getting too much information from them. The few quizzes that I have had it is hard to not cleat when you have the opportunity to do it. I think that the workload is a lot and you do not really think about how much work you do at school because you are at school, but when you are at home you have to focus yourself and do all your work with limited help. I also understand that this must be hard on the teachers to help the students and to get their work done as well. I feel like this time is really difficult, but I also feel that the difficulties we face during cyber school are better th

The plague in Athens vs. COVID-19

Today our assignment was to compare the plague that hit Athens to COVID-19. The main difference that I first think of is that the plague in Athens was not a pandemic like COVID-19 is. A second difference is that the plague in Athens lasted for 4 years, hopefully there is a difference here and COVID-19 will not last that long. A third difference is that the plague came from Africa and COVID-19 comes from China. Another thing that I hope to be a difference is the fact that the plague killed 1/3 of the population, and I hope that COVID-19 does not kill that many people. As a last difference the plague does not seem like something many people survived, while coronavirus many people will survive and recover quickly. A similarity of the two diseases are the symptoms. According to the internet the symptoms of coronavirus are: - cough -fever -tiredness -difficulty breathing (severe cases) According to Thucydides the symptoms of the plague in Athens were: "Violent heats in the head;

Alexander and Bucephalus

Today we were assigned to research about the relationship between Alexander the Great and his horse Bucephalus. I found a lot of information about them and their special relationship. I found that they were inseparable and that Alexander was the only one that could ride him. Alexander met Bucephalus  when he was brought to Macedonia and presented to Alexander's father. Everyone thought that the horse was wild, and Alexander's father wanted him to be sent away. Alexander went against his father and stood up and asked to keep him. He approached the horse and named him. Alexander found out why Bucephalus was acting so crazy and that was because he was afraid of his own shadow. Alexander mounted him right there and rode him away. Starting from that first day when Bucephalus and Alexander met they had a unique relationship and went through many battles together and ended up dying after the Battle of Hydaspes River. I used to own a horse of my own and can relate to some extent on the
