USE OF GRADE 9 LABORATORY DURING EXPERIMENTATION  01 PRE - EXPERIMENTA TION Things to remember. PRE-EXPERIMENTATION 1. Identify ALL materials needed 2. Step-by-step procedure (include time frame if possible). “START to FINISH” Procedure. 3. Read and understand all procedures, do not proceed if you do not understand a part of the procedure. 4. Prepare tables/charts where your data will be placed. PRE-EXPERIMENTATION 5. Equip all materials needed before going to the lab (must include the following: dish soap, sponge, alcohol, tissue/clean cloth, masking tape, marker/pen) 6. Laboratory Letters (letter of request, lab use, etc.) – include the intel-ISEF forms for those under life science, physical science (who will use chemicals). REQUESTS MUST BE DONE AT LEAST 3 DAYS PRIOR THE REQUESTED MATERIALS/LABORATORY. PRE-EXPERIMENTATION 7. Some experiments may be done at home like the following: ○ Robotics and simple machine (prototype) ○ Information technology and computer systems (programming, coding, etc.) ○ Simple physical laboratory techniques (drying, grinding, maceration, decoction, boiling, etc.) PRE-EXPERIMENTATION 8. Experiments done in the lab include the following: ○ Life science (antimicrobial testing, cytotoxicity testing, mice use, insect use) ○ Physical science (use of strong chemicals, deep extraction methods, use of very high and low temperatures)  02 ACTUAL EXPERIMENTATI ON Special reminders! ACTUAL EXPERIMENTATION 1.Wear and observe proper attire during experimentation. 2.Prepare your own laboratory box/basin/tray (you will place here your materials) – label and store properly in the lab. 3.During experimentation, always observe the Do’s and Don’ts of the experiment and laboratory. ACTUAL EXPERIMENTATION 4. Observe and follow strictly the given timeframe. There is no room for redoing your experiment. 5. After using the borrowed materials from the lab, clean and wipe dry all materials before returning. NOTE: MAKE SURE TO GATHER ALL NEEDED DATA DURING AND AFTER THE EXPERIMENT. POST LABORATORY What to do when done with the experiment? POST LABORATORY 1.Collect and record all needed data from the experiment. Present the data using charts/graphs. 2.Prepare data to be used for data analysis. 3.Review your Data Analysis tools. 4.Analyze and interpret your data.  REMINDER! The research adviser will only be available during scheduled laboratory work (class hours). If you wish to work at home or in the lab without your adviser, please seek help from the custodian or someone older who can assist you in your experiment. Scheduled experiments at PSHS-CARC must always be assisted by the adviser. REQUEST LETTERS Must be reproduced in 3 copies: a) 1 receiving (to be kept by the researchers) b) 1 for the adviser c) 1 for the laboratory custodian
