Are you teaching the process of science? Does your objective read, students will know the parts of the scientific method? This article has variables, constants, questions, conclusions, and data. It can be taught at Halloween because the science is important for would-be vampires.
Each student receives a handout. While you take attendance, each student reads the short summary that addresses the question, "How Long Does It Take for a Vampire to Drain Blood?" Each student highlights and follows directions. Those who forgot their highlighter, underline the required information. Ten minutes is generally all students need to complete the initial activity and word scramble.
After attendance, review the article with the class, go over the areas that should have been highlighted and word scramble answers. If you have a word wall have your students choose three words they want to post on the wall with definitions. Examples include fluid dynamics, blood pressure, variables, etc.
If you are using my bellwork form, each student enters "Dracula Science: How Long Does It Take for a Vampire to Drain Blood?" in the daily box, and staples his/her work to the bellwork sheet for collection on Friday.
Last note, this reading activity can dovetail with any current reading effort of your school. Administrators appreciate that a Science teacher is assisting in the effort. You can use it as a pair/share activity. If you want to augment this introduction with notes on the parts of the scientific method, or how this research is practical in the real world, then you have a complete lesson, and some interesting topics for discussion.
The "Ticket Out the Door" will make your lesson complete.
