In Class lab experiment worksheet (see attachment)

HWK due typed Bibliography, Journal entry #17, #18 below.

Journal Entry #17  Variables

1.  
   1. What variables ( at least 10 ) are important in your scientific study?
   2. Describe how you will measure each of these variables. Include units and names of measuring equipment.
   3. Next to each variable write whether it is a quantitative or qualitative. Write a brief paragraph describe the difference between quantitative and qualitative variables.
   4. Is your experiment controlled? Why or why not? What does it mean to have a controlled experiment?
   5. What are constants? What will you set your constants as? Provide reasoning for each setting.

Journal Entry #18 Data table

Directions:  Draw a data table for your independent and dependent variables. Include the units. List the 4 levels of the independent variable you will test. Include room for 5 trials.

In Class  Journal Entry #19 see schedule below copy into notebook, Group 1: acid/base & displacement Group 2: endo/exo Group 3: electrolysis/battery

Sample Data :

• 10 grams of Zn + 50mL of 1M HCl produced a temperature in Celsius of 45, 33, 43, and  42.
• 20 grams of Zn + 50mL of 1M HCl produced a temperature in Celsius of 47, 45, 45, and  49.
• 30 grams of Zn + 50mL of 1M HC; produced a temperature in Celsius of 52, 49, 53, and  52.

Journal Entry #20 Data Analysis
Directions: Use the sample data above to answer the questions below in complete sentences in your notebook.

1. Use the sample data above to create a data table.
2. What is the independent and dependent variable of this experiment? Which variables are kept constant? How do you know?
3. What are the levels of the independent variable? How many are there? How many trials were performed?
4. Calculate the average of each level of the IV. Explain how it was calculated and why it is significant.
5. Is this data positively or negatively correlated or is there no correlation? Explain your reasoning.
6. Are the number of trials and levels sufficient to conclude how the independent and dependent variable are correlated? Explain.
7. If a student were to redo this experiment what changes would you propose?

Journal Entry #21 Error Analysis Questions
Directions: Use the sample data above to answer the questions below in complete sentences in your notebook.

1. Explain in your own words what is an "outlier" in terms of data sets?
2. How do you find an outlier in a data set? How would you compare each point?
3. Are there any outliers in the data? Where would you look to figure this out?
