PROJECT-7th grade accelerated science- due THURSDAY 2/13 SCROLL ALL THE WAY DOWN FOR THE RUBRIC PICTURE Humans have long altered the genes of organisms through selective breeding (e.g., cattle, dogs, corn). Recently, however, advances in our understanding of DNA have enabled us to modify organisms by directly altering the genes of these organisms, a technique called genetic engineering. The rapid advances of genetic engineering have brought about great possibilities for ways to combat world hunger, malnutrition, illness, and infertility. With these advances have come real ethical questions about how much we should manipulate DNA, or whether we should manipulate it at all. Your job is to choose one to the genetic engineering topics below. You are to use the information you find to formulate a solid argument for or against the topic you have chosen. You will create a poster to share what you have learned and your opinion. Requirements: You must have scientifically valid resources to back up your claims. You may use Wikipedia for one source, but be careful and make sure your information is backed up by at least one other source. You must have at least 3 sources for your information. Your poster should: Have an informative title Give an overview of the topic detailing opposing viewpoints (respectfully) Explain at least three scientifically valid reasons to support your stance Explain at least three reasons to oppose your stance A conclusion explaining and describing the reasoning behind your viewpoint A glossary of at least 3 words defined USE ACADEMIC VOCABULARY! INCLUDE MANY PICTURES! BE NEAT! BE ORGANIZED!
Points to consider (you do not have to include them all, but you may): Why was this application developed? How is it being used in the real world? How does this application affect the diversity of living things on Earth? Why do you find this interesting? What are the ethical issues? What is next for this technology?
RUBRIC POSTED ON BLOG DUE DATE: FEBRUARY 13
TOPICS TO CHOOSE FROM Genetically modified foods Genetically modified organisms for use in medicines Uses of Stem cells Cloning non-human organisms (dogs, sheep, etc.) Genetic enhancement (“designer babies”) Genetically modified animals as pets (for example, fish) Genetically modified organisms for use in public safety (for example, dogs, mice) Transgenic organisms Gene therapy (uses in healthcare, non-medicine) Genetic engineering uses in extending life Reproductive technology Genetic engineering uses in forensics Genetic engineering uses in maintaining ecosystems and populations Genetic engineering uses in recovering extinct species
Homework #50 Using your best artistic skills, draw and label DNA being copied to RNA (some of you are cringing right now, but try your best.

Chloe wanted to find out if the color of a food would affect how quickly kindergarten children would eat it for lunch. She believed that brightly colored food would be eaten more quickly because of the urgency of the color. She put food coloring into 4 identical serving bowls filled with mashed potatoes. A 5th identical bowl received only plain natural mashed potatoes. The colors were natural white, red, blue, green, and yellow. Each child was given a scoop of potatoes. Chloe did this experiment using 50 kindergarten students. 10 students were given each of the colors. She recorded the start and finish time of each student eating the potatoes and then calculated the difference in seconds. She did this over 5 days with each student getting each color. Multiple data takers (Chloe’s friends) made this experiment possible. QUESTIONS 1. State the problem Chloe wants to answer (question): 2. What is the independent variable? 3, What is the dependent variable? 4. List two constants 5. What is the control for this experiment?
