Data/Field/Experimentation Log
Data Log Book (Composition Notebook) Due October 31, 2018
​
A Data Log is a day to day, hand-written record of ALL activities while performing your experiment. It tells what was done, where it was done, how it was done, and especially when it was done.
This log book is the factual collection of every part of your project, written by the hand of the scientist; it is the most valuable part of your project.
Please do not erase anything - just mark through it if you make a mistake. You may use a pen or pencil (just don't erase!)
Do not tear our pages.
Each day please begin a new page. Do not put several entries on one page unless your composition book is getting too full.
This Data Log should be in composition book and must include the date of every entry. Your log should be a recording of your daily observations and measurements; both quantitative (measurements) and qualitative (observations) should be included in your log. Each piece of quantitative should be accompanied by qualitative data. If you have a supervisor present, he or she should sign your log book.

Sample Entry:
Monday, October 1, 2018
Today I received the planaria from Carolina Biological in the mail. I took the container out of the box and let it sit for an hour to come to room temperature. After an hour, I put 3 ounces of distilled water in each of the twelve plastic four ounce jars and put one planaria in each jar. I fed each planaria a pea-sized portion of liver. In Jars 1-4 I placed 2cc of caffeine water, in jars 5-8, I placed 4 cc of caffeine water, and in jars 9-12 I did not add any caffeine. I then placed the jars in the cool, dark experimental closet.

I got the 12 jars of planaria, emptied the water in each jar and replaced 3 ounces of distilled water in each. I added 2cc of caffeine water to jars 1-4; added 4cc of caffeine water to jars 5-8; and added no caffeine to jars 8-12. I noticed that the planaria in jar 5 wasn't moving, but he appears to still be alive. I put them back in the experimental closet and plan to measure them tomorrow for growth.
