Introduction
Scenario: You, a 17-year-old student, tend to be clumsy at times and happen to scratch your face while exercising. After the bleeding is over you apply topical antibiotic and a band-aid. The problem? The homecoming dance is only six weeks away and you are worried about the scratch turning into a scar. The solution? Try to find a medicine that will reduce the chance of a scar forming. But, you don't trust your beautiful face to just any scar-reducing cream! You want to understand how scars form and what the medicine will do to reduce it, before you trust putting it on your face.
Webquest Purpose: To help understand how scars form and how scar-reducing medicine works, you will: research the different types of tissues in your body, determine which type of tissue causes scars and how, and determine how scar-reducing creams work. You will then make your determination if scar-reducing medicine is a viable choice to put on your scratch.
Ready to start your project? Then move on the the Task section!
Task
There are four steps to your task:
1. Research the four types of tissues in your body. They are: epithelial, connective, muscular, and nervous.
2. Determine which type of tissue causes scars and how scars form.
3. Research scar-reducing creams including how they work and what they are made from.
4. Create a project to share what you have learned and answer whether you will use scar-reducing cream on your scratch, using evidence you have gathered.
Ready..set...GO!
Process
Step 1: To research about the types of tissue, click on the links below and read the information. You will also need to use your chapter booklet. Please take notes as you go. You may also choose to watch the videos to help in your learning.
National Cancer Institute: SEER Training Modules
Mc-Graw-Hill Company: Tissue of the Human Body
Georgia Highlands College: Classification of Tissues
If you choose to watch the videos, please watch them in order to benefit your understanding.

Tissues of the Human Body: What is Epithelial Tissue? (Video 3)
Tissues of the Human Body: What is Neural Tissue? (Video 4)
Tissues of the Human Body: What is Physiology? (Video 5- this video explains muscular tissue)
Step 2: Research what type of tissue causes scars and how scars form- specifically looking for scars that form on skin, similar to the scratch you received. Click on the links below and again take notes as you go.

Step 3: Research Mederma ®, a common scar-reducing medicine. Mederma ® is a very well-known cream that is said to reduce the visibility and appearance of scars and is stated as the #1 brand recommended by doctors. If you trust any medicine to put on your beautiful face, it might be Mederma ® but you want to make sure it is safe and that you understand how it works, before you try it.

Step 4: Using the notes you have taken so far in this webquest, create a project to show what you have learned and what you have decided about using Mederma ®.
Project: Create a presentation explaining the four types of tissues and scars. Details: The report needs to be descriptive and explain the information in a detailed manner. It can be computer-generated or hand-written, as long as the hand-writing is neat and legible! The report needs to be written for a high school or adult audience, so make sure the writing is age-appropriate. Very important: write in your own words! Learn the information and write what you learned, do not just copy and paste from online resources. You may use some cited information but make sure to accurately cite your resources! There is no minimum or maximum length the presentation needs to be, as long as it includes all the information.
Requirements for project:
1. Include ALL of the information listed below!
- Describe all four types of tissues and their functions including the subtypes or different classifications for epithelial, connective, and muscular tissue.
- Name several specific locations where each type of tissue can be found.
- Describe specific details or unique characteristics of each type of tissue.
- Describe how scars form, including what type of tissue creates scars and why scars look different than the rest of the skin.
- Describe how scar-reducing creams such as Mederma® work.
- Discuss why you would or would not use a scar-reducing cream on your facial scratch and explain your reasoning.
2. Make sure your project is neat, creative, and easy to read/view.
3. Do your own work!!
4. Cite your resources at the end of your project.
5. Have grading rubric on top of your project when you turn in.
6. Have completed project turned in by the due date!
Grading
Your project will be graded with a rubric. To see the rubric, go to the Evaluation page of the webquest.
