Week 1 – Laboratory

 

Scientific Method
 

Welcome to the Week One lab. Prior to working on the lab exercise, watch the How to Formulate a Hypothesis video.
 

By completing the Week One lab exercise, you will learn how to look at data using the scientific method. This includes scientific observation, variables, controls, errors, methods of collecting data, data analysis, calculations, scientific reasoning, and writing a lab report. In the exercise, you are asked to partner with another person, who is capable of doing physical exercise for one minute. A resting heart rate and post-exercise heart rate will be taken and recorded. Use the heart rate information to complete the Respiratory and Heart Rate Table.  You will create a hypothesis to predict what the physiological response is to exercise and how this helps the body maintain homeostasis. Finally, answer lab questions that address the different elements of the scientific method.
 

You will complete your answers on the Lab Report form linked in the Week One lab exercise area on the eScienceLab portal. Please open the form, click on File, choose Save As, and save to a folder where you can find the form later, add your answers, and Save again. Finally, you will attach and submit the form to Waypoint   in the Week One Laboratory in the Ashford University classroom. Please note: the document must be attached and submitted to Waypoint  . Assignments that are copied and pasted into the comment box or emailed to the instructor will not be accepted and will receive a zero score.
 

Your assignment must be formatted according to APA guidelines as outlined in the Ashford Writing Center.
 

Carefully review the Grading Rubric for the criteria that will be used to evaluate your assignment.

Week 1 Assignment: Evaluating Homeostasis

Submission Instructions: Please complete your answers to the lab questions on this form. Please complete your answers, and SAVE the file in a location which you will be able to find again. Then, attach and submit the completed form to the Week 1 Laboratory dropbox in the Ashford University classroom.

Hypothesis:

Post-Lab Questions:

1. Is your dataquantitative or qualitative? How do you know?

2. What type of graph would you use to represent the data from Table 4?

3. Does the data support your hypothesis from Step 1? Why or why not?

4. What is the independent variable in this experiment? What is the dependent variable?

5. What other variables could be tested in this experimental set up?

6. Use the following template to complete a lab report as described in the introduction.
