A lab-oriented competition involving the fundamental science processes of a middle school life science/biology lab program.
Event Parameters
1. Teams of 2
2. #4 eye protection
3. Each team may bring one 8.5” x 11” two-sided page of notes that contain information in any form from any source.
Eye Protection
Contestants are responsible for providing their own protective eyewear. Teams MUST NOT be allowed to compete without adequate eye protection. This in NON-NEGOTIABLE.
# 4 Goggles provide chemical/splash protection (ANSI Z87)These must seal tightly to the face completely around the eyes and have indirect vents. (Liquids do not have a direct path into the eye.)
Team Preparation
Work as a team, divide the work and collaborate as needed.
Set up sample stations
Practice lab skills
Do practice exams and questions
Work with time limits
Have Fun!!
