We take that position, too, David. Since we first wrote our own lab manual 5 years ago, the first page of every experiment has been ten advance study questions with the following instructions:

"To show your understanding of the material in this experiment, print your answers to the following questions on a computer using Microsoft Word or equivalent application to print text and equations and to draw graphics. Hand in your printed pages, not this page, at the beginning of lab class."

For example, the advance study questions for Experiment 2 on Measurement and Data Analysis (which uses Pasco sensors and Science Workshop software) include these six:

1. Describe the difference between uncertainty and error in measured and calculated values.

2. Explain how the motion sensor used in this experiment calculates distance by measuring time.

3. Show that in multiplication, the relative uncertainty of the product is the sum of the relative uncertainties of the two factors.

4. Explain the difference between analog and digital displays of measured values.

5. Write the following values with the correct precision in scientific notation (powers of ten) in the units given:
(a) 0.0925 gram (b) 3,757,500 second (c) 13/128 centimeter (d) 9,005,275 gram (e) 73,992 second (f) p/72 centimeter

6. Solve the following expression on your calculator: 4p(635)/17 =

We believe this practice has encouraged our students to study the experiment before they come to lab class.

I'd be interested too. In general though I would be happy if they read the lab ahead of time. I've thought about a pre-lab quiz that would make them read it. No time though.

Greetings Tappers:

We're revising lab manuals (don't we all this time of year?) and I'm looking for tried and tested "pre-lab activities" - no sense in re-inventing the wheel if you know what I mean.
Anyway, does anyone have a library of these to share for calculus based mechanics/fluids/waves?

Thanks - I'd be happy to list these on a web site if I get multiple submissions.
