Required Materials: Each participant must bring safety equipment (e.g., goggles, lab coat, apron),writing instrument, and 1 stand-alone calculator of any type. Participants must wear goggles, an apron or a lab coat and have skin covered from the neck down to the wrist and toes (gloves are optional, the host will notify teams if a specific type is required). Shoulder length or longer hair must be tied back. Participants removing safety clothing/goggles or unsafely handling materials or equipment will be penalized or disqualified from the event. Supervisors will provide any required reagents, additional glassware, and/or references that are needed for the tasks (e.g., Periodic Table, table of standard reduction potentials, any constants needed).
Clarifications: For the Chemistry events, it states that teams may bring any or all of the items listed – are teams only permitted to have the checked items in their kits? Or, may they have all items on the list even if they are not checked.
Description:
This event is a lab event typically done as stations that teams rotate through, it can also be done as a sit down test if there are enough materials for everyone to have a complete set. Teams will need to be aware of and follow all chemistry lab safety procedures. Teams will be presented with a series of questions and tasks that they must complete. These may include but are not limited to: interpreting written data/graphs, collecting data, making calculations, etc. The topic for the 2020 tournament year are Aqueous Solutions and Acids & Bases.
Materials:
a. Each participant must bring safety equipment (e.g., goggles, lab coat, apron), a writing implement, and may bring a stand-alone non-programmable, non-graphing calculator. Each participant may bring one 8.5” x 11” sheet of paper, in a sheet protector or laminated, with information on both sides in any form and from any source along with any or all of the items listed as Recommended Lab Equipment for Division C Chemistry Events, posted on soinc.org. Teams not bringing these items will be at a disadvantage, as they are not provided. Participants must wear goggles, an apron or a lab coat and have skin covered from the neck down to the wrist and toes (gloves are optional, the host will notify teams if a specific type is required). Pants should be loose fitting; if the host has more specific guidelines they will notify teams in advance of the tournament. Shoulder length or longer hair must be tied back. Participants removing safety clothing/goggles or unsafely handling materials or equipment will be penalized or disqualified from the event.
***SAFETY ISSUE*** In addition to OSHA approved chemical splash goggles, teams also MUST wear closed toed shoes, clothes that cover the student from neck to wrist and ankles, AND a chemical apron with a long sleeved shirt or lab coat that reaches below the knee , and long hair must be tied back or they will not be allowed to participate. In addition, any teams seen handling materials in an unsafe manner will be disqualified from the event.
Event Leaders will provide a proper lab environment, any materials/glassware appropriate for the questions asked, a periodic table, and any constants needed.
