2021 Information Search Topic: Disinfectants
EVENT 07 INFORMATION SEARCH 2021 TOPIC:
OBJECTIVE & BACKGROUND
Disinfection has an important role in the prevention of the spread of illness. Implementation of disinfection protocols to reduce the spread of COVID-19 has resulted in the reduction of other community-acquired diseases such as seasonal influenza.
The following compounds are used in disinfectants approved by the USEPA or Health Canada and have helped us in the fight against COVID-19. Yet like many other chemicals, there are positive and negative aspects of their use. You will build a model of one of these five compounds, and during the live event, answer questions on their history, chemical properties, and use using properly cited peer-reviewed or academic online resources.
Tetraacetylethylenediamine, CAS 10543-57-4
5-Chloro-2-(2,4-dichlorophenoxy)phenol, CAS 3380-34-5
Thymol, CAS 89-83-8
Trichloroisocyanuric acid, CAS 87-90-1
2-bromo-2-nitro-1,3-propanediol, CAS 52-51-7
EVENT SPECIFIC REQUIREMENTS:
A team of 2 or 3 students must compete in this event.
Schools with more than one team MUST select different molecules to research and present. The teams MUST compete in the same time slot.
BEFORE the day of the event, the team will select one of the molecules and make a molecular model using low-density Styrofoam balls and wooden skewers. ***Exceptions due to the pandemic must be pre-approved, email Dr. Gulotta.***
The team should be prepared to use the Internet to answer general knowledge questions about all the molecules in the Information Search portion of the event.
The Information Search portion of the event is to be completed in 25 minutes ON THE DAY OF COMPETITION.
The team should be prepared to answer two oral questions about their molecule.
Question #1 will focus on molecular geometry (such as chirality, identifying co-planar atoms, hybridization, bond lengths, and angles).
Question #2 will focus on the relationship between structure and function. Note: Students are not expected to know specific proprietary information about the compounds. They should however, understand the importance and role of different functional groups
EVENT DAY INFORMATION:
On Event Day each team should have one representative have their model available for judging who may be asked to move and rotate the model for the judges. During the allocated session, each team will participate in the "Internet Search" and "Molecule Questioning" portions of the event.
Teams will be asked six Information Search questions. In order to provide written answers to the six questions, each team will be provided with one computer with access to the Internet. At the completion of scheduled session, each team must submit their written answers to the questions provided. See example questions from previous events.
On the day of the competition, student teams will be asked two questions about their model. Teams will orally respond to the questions in order to demonstrate their knowledge and clarify their reasoning. Student responses should not exceed 3 minutes. Students may also be asked points of clarification if there is any confusion about their model.
