Yesterday and today students had the opportunity to 'play' in the lab using their experimental designs. Here are some of the things they learned:
It's nearly impossible to transfer yogurt into dialysis tubing.
"Place half of the potato in water" is a completely unacceptable statement in a procedure.
Knowing what equipment is available will making writing a procedure much easier.
Measure in grams, not in "pinches" or "teaspoons."
After you've had a chance to 'play' it's OK and sometimes advisable to completely change your procedure.
Be Specific!
Be Specific!
Be Specific!
Tomorrow you will have class time to continue working on your designs. The final design, following the guidelines you were given in class (at the back of the packet and have been emailed) will be due on Monday or Tuesday, depending on when your class meets. You MUST have a printed copy of this assignment.
