Diphtheria has broken out in Nome, Alaska. Teams of sled dogs carry medicine 800 miles over snow and ice to prevent an epidemic. Everyone was brave but one dog, Balto, made the difference between failure and success.
In this video module, students learn how scientists use genetic information from dogs to find out which gene (out of all 20,000 dog genes) is associated with any specific trait or disease of interest. This method involves comparing hundreds of dogs with the trait to hundreds of dogs not displaying the trait, and examining which position on the dog DNA is correlated with the trait (i.e. has one DNA sequence in dogs with the trait but another DNA sequence in dogs not displaying the trait). Students will also learn something about the history of dog breeds and how this history helps us find genes.
This submission is about learning from our environment through the eyes of dogs. learning what is in our woods when we are not there. Learning about what we find. Discovering what is in the wilderness for those who are unable to get out there and see it first hand.
Students will learn how to describe pets in Spanish by drawing their own pet or desired pet. Students will describe how their pet looks and its characteristics. After describing their pet, students will share how their pet looks and how their pet acts to a partner. This activity familiarizes students with different animals and descriptions of animals.
Students create and decode DNA for mans best friend to observe how variations in DNA lead to the inheritance of different traits. Strips of paper that represent DNA are randomly selected and used to assemble the dog's DNA. Students read the DNA and create a drawing of their pet, and compare it with others in the class to check for similarities and differences.
