During the course of four to five class lessons, the teacher will present the handout entitled "Introduction to the Age of Discovery". Students will identify the reasons for exploration. The students will underline the key figures who are involved. The teacher will then present two PowerPoint Presentations. The first is entitled "Glory, God or Gold". The second is entitled "Colonization of the New World 1600- 1750". The teacher will place the slide shows on the screen via the video projector. The students will have copies of the two slide shows in printed handout form. Once the two presentations have been read, the students will answer the cause and effect comprehension questions located on the last slide of each presentation. Next, the teacher will present the students with primary source documents from Columbus, Prince Henry, Magellan and Vasco Da Gama. The students will summarize the documents. The students will read pages 307-311 in World Cultures and Geography textbook and complete the main idea questions on page 311. Students will then create a timeline of European explorers and their routes. Last, students will watch a video from www.unitedstreaming.com which will list the three explorations of Prince Henry, Magellan and most importantly Christopher Columbus along with the results of the Columbian Exchange. The students will take notes on the video.
The students will be presented with a list of resources (textbook, handouts and primary source documents) which will give students the informational background necessary to determine the causes and effects of viruses and identification of Smallpox, Influenza and Measles. During this phase of the unit, the teacher and students will utilize the computer laboratory and media center. The Library Media Specialist will assist with this portion of the unit.
Diseases have diverse causes, which can be classified into two broad groups: infectious and noninfectious. Infectious diseases can spread from one person to another and are caused by microscopic organisms that invade the body. Noninfectious diseases are not communicated from person to person and do not have, or are not known to involve, infectious agents.
Transmission of disease varies. Pathogens can be spread through direct contact or via air. Pathogens leave the first person through body openings, mucous membranes, and skin wounds, and they enter the second person through similar channels. For example, the viruses that cause respiratory diseases such as influenza and the common cold are spread in moisture droplets when an infected person coughs or sneezes. A hand that was used to cover the mouth while coughing contains viruses that may be passed to doorknobs, so that the next person to touch the doorknob has a chance of picking up the infectious agent. Other pathogens involve an intermediary carrier, such as an insect that vector transmits the pathogen from person to person as it feeds (e.g., mosquito).
The viruses of Smallpox, Influenza and Measles are the focus of the unit. These diseases primarily affected the development of the continent of North America. Students will need to know the difference between bacteria and viruses and how pathogen transmission occurs.
