*There is a metric conversion chart in the back of your text.

The three sections that you must complete are listed below with directions.

• Units of Measurement: Read this section.
• Measuring: Record the data and save the information in one Word document (with the other exercises under Measuring) which you will then send to your instructor via Web CT. Exclude the part with the dropper. For the length, volume I and volume II, and temperature (but not mass) parts of the exercise, simply copy and paste the page into your Word document before filling in the answers in the Word document. Do not do the rice, dinosaur, and population labs.
• Experiment: You are to complete this experiment, but a small glass or tall cylinder may be used in place of the test tube containing the potatoes. Be sure to print and save the data from this experiment, but you do not need to include it in your emailed document. What you do need to email to your instructor is the answer to the following question: What was the effect of the temperature on the reaction of the catalase with the hydrogen peroxide?
