Scavenger Hunt

Lesson Objective:

1.     Using the web scavenger hunt, students will access the websites provided by correctly using the URL, read the web page with grade appropriate understanding, and define 5 of the vocabulary terms from the chapter. (Bloom’s Taxonomy: Knowledge, Comprehension) 
2.     Using the web scavenger hunt, students will understand the basics about bacteria and viruses. (Bloom’s Taxonomy: Comprehension)
3.     Using the web scavenger hunt; students will develop a chart that distinguishes the differences and similarities between viruses and bacterium. (Bloom’s Taxonomy: Application, Analysis)
4.     Using the web scavenger hunt, students will decide and defend their stance on the use of vaccinations. (Bloom’s Taxonomy: Evaluation)
