Science and Technology Standards Understandings About Science and Technology Technology is essential to science because it provides instruments and techniques that enable scientists to make observations of objects and phenomena that are otherwise unobservable. Scientific Inquiry Students conduct an investigation by testing the effect of disinfectant on the growth of microorganisms. Students use evidence from that investigation to propose explanations for why they should wash their hands when they have been coughing. One way to minimize disease is to sanitize and disinfect. The Interdependence of Organisms, Grades 9-12 Organisms both cooperate and compete in ecosystems.
Humans use disinfectants to compete with pathenogenic microorganisms.
History and Nature of Science Standards Science as a Human Endeavor, Grades 9-12 Scientists are influenced by societal, cultural, and personal beliefs and ways of viewing the world. Cultural preferences determine what products scientists develop and the characteristics of the products. Some diseases and illnesses can be prevented by good personal hygiene such as handwashing with soap. Page maintained by Steve Gentle, Research Associate.
