Acids and Bases Webquest
Part 1: Acids and Bases Introduction:
Go to the http://www.chem4kids.com/files/react_acidbase.html and read about acids and
bases. Complete all 4 parts of the webquest on a loose leaf piece of paper. Make sure to
answer all 7 questions, data table, and reflections questions.
1. What is an acid? What is a base?
2. How do scientists measure the strength of acids and bases? Describe this scale.
Next, we will take a look at some examples of acids and bases.
Go to the VisionLearning Website and learn more about the properties of acids and bases.
3. Describe the physical properties such as taste and feel of acids and bases.
4. Give 3 examples of acids and 3 examples of bases from the pH Scale on the site.
Part 2: Understanding the pH scale:
Go to the The pH Factor website. Create a table on your loose leaf paper with the following
columns. Record the pH and other information in the chart for all 12 of the substances.
Table 1: pH Panel
Substance
pH
Acid, Base or Color of pH paper
Neutral
Color of Cabbage
Juice
Lemon Juice
Baking Soda
Aspirin
Ammonia
Milk of Magnesia
Lava Soap
Borax
Water
Lemon Soap
Vinegar
Tonic Water
Liquid Plumber
(Now that you finished the table, take a look at this: Red Cabbage Juice pH indicator)
Part 3: Acid/Base Neutralization:
Go to the GEMS Alien Juice Bar Website and complete the 3 challenges. When you are done
with one challenge, click on the “Main Menu” Button to go to complete another challenge.
5. How do you neutralize an acid? How do you neutralize a base?
Go to the Teacher’s Domain website.
 Type in aprende for username
 Type in student for the password
 Type “Acids and Bases” in the search and Click on “View” next to the video you want to
watch. Begin with the Acids and Bases: Kitchen Chemistry video.
6. Name a base that you could use to neutralize an acid.
7. What is an acid base indicator? Give an example used during the video.
Part 4: Reflection Questions:
1. What did you already know about acids and bases before you began the webquest?
2. What were two things that you learned about acids and bases from the webquest?
3. What is one question you still have about acids and bases?
Extension Activities:
Games:
Acids Bases and Salts: You can choose whether to be timed or not...it's up to you. Like a game
of memory click on two of the cards and when you think they go together (one will be the word
the other should be the definition) click on Match.
Virtual Kitchen: Read the directions on each page as you click the buttons to continue. Once in
the kitchen click on the postcard and read the directions.
Find and write down the the 6 hidden clues (check everything!!)
Bonus Question:
What is the pattern from the cabbage juice and cork tests?
