These fantasies have captured the hearts of children and adults alike for many years. ?For this assignment, you will create a fairy tale that will no doubt capture the hearts of your peers, as well.Description:For this assignment, you will choose a toxin on which you will need to conduct research. ?You will write a fairy tale that incorporates your assigned toxin (as it will be the villain’s weapon of choice). ?You have the choice of either writing a storybook with a partner OR creating a story board poster with a partner.In writing your “toxic” fairy tale, you must adhere to the following guidelines:Narrative/script is typed/neatly handwritten & includes original title and picturesStory is original, created by you (and your partner, as applicable)Story includes at least the following characters: a heroine (e.g., princess), hero (e.g., prince), and villain (e.g., evil witch)During the rising action of the story, the heroine or hero is poisoned (with your toxin) by the villain Story in some way includes a description of the poison, where it comes from, how it’s generally used (e.g., medicinally or in certain products), etc.Mode of toxin’s entry into heroine’s or hero’s body is included (e.g., ingested, inhaled, absorbed through skin; based on your research) The symptoms experienced by the heroine or hero are explained or portrayed in some way (based on your research)In the end, the heroine or hero is rescued by the hero or heroine who treats her/him for her/his symptoms (include the type of treatment, based on your research)For a few bonus points include modern day heroine or hero that has died by the same poison in your storyToxins: Anthrax ????????????

Choose your option (PowerPoint, Poster, Brochure, Booklet, student created/teacher approved) for presenting the following information:Title: What: ?Brief description of case Who: victim, suspect, & their relationship Any other key players (witnesses, lawyers, experts)When/ Where:Year, geographic location (ex: San Diego, CA, or Chicago, IL)Physical location/ time of dayEvidence:Forensic evidence - Poison or Drugs involved, how they were identified, forensic tests involved, etc.Witness testimonyHow did the suspect become a suspect?Did suspect have a motive? Explain.Outcome:Legal outcome (who was charged? What were they charged with? Did they go to prison?)Reflections:Why do you think this case is famous?Be sure to include a list of your resources and pictures related to the case. Color will enhance your project. ................
