PRE-LAB ASSIGNMENT
*This pre-lab assignment is required for some of the labs in the course.
*Due at the beginning of period on the day of the lab. It must be completed for you to be allowed into the
lab. Any student with an incomplete pre-lab will receive a zero for the entire lab.
*Counts as 10 points of total lab grade.
1. State the hypothesis. Identify it as the hypothesis. You may use “If/Then” statements.
2. Identify the control group that will be used for comparison. (It does not contain the variable being
tested.)
3. Identify the dependent variable.
4. Identify the independent variable.
5. Identify any other variables that are being held constant in the experimental group. For instance, each
setup may be measured for the same amount of time; or each setup may have the same amount of
solution in each beaker, etc.
6. Identify what is being measured. (Example: CO2 or H20 consumption; growth; production of a product;
etc.)
7. What method and/or time frame is used? Example: I will take readings of…every 5 minutes for 30
minutes.
8. What is the rate of calculation and/or statistical application? Example: average number of trials, slope
of the curve, etc.
9. How will the results be verified? (sample size or repetition)
10. How will the experimental results be presented? (graphs, charts, etc.)
11. What are the expected results? Why? This is your best prediction based on reading the lab and any
other information you obtain. (Other sources of information may be your book, the internet, class lecture,
etc.)
