5 Questions/5 Answers
Think of 5 questions that will help us get a better understanding of our Phenomenon Question and what is going on with the onion and our eyes.
Once you have your questions, do some research to help you find your answers.

MindMap
Using the answers from your 5Qs/5As, create a MindMap, using the keywords from your questions and answers. Remember, MindMaps are similar to outlines we only want to use one, two, or three words to express any specific idea.
Chemical Reaction Reading, Demo, and Activity
READING
Before we get started, lets go over some information that will help us learn more about chemical reactions, how and why they happen. In pairs, read the following pages from Chem4Kids:
http://chem4kids.com/files/chemistry.html
http://chem4kids.com/files/matter_intro.html
http://www.chem4kids.com/files/matter_chemphys.html
http://chem4kids.com/files/react_intro.html
http://chem4kids.com/files/react_rates.html
http://chem4kids.com/files/react_thermo.html
In your science journal be sure to take notes on the key concepts that are being presented. Also, be sure to write down the key words (bolded words) and their definitions. This will help when we do our activities and labs, and when we do our Quizlet.

MindMap - Take 2
Review your notes from the articles and the video, "Why onions make us cry?" and add the information to your MindMap. Think about the chemical reaction that occurs and what is involved. Pull out the key words we talked about, including the names of the enzymes involved in the chemical reactions. Also be sure to include information on your eyes and what is happening on that end.
Quizlet
Create a set of Quizlet cards for the following words:
- Chemical Reaction
- Molecule
- Compound
- Mixture (use chemistry definition)
- Flammability
- Solubility
- State of Matter
- Malleability
- Product (use chemistry definition)
- Reactant (use chemistry definition)
- Enzyme
- Law of Conservation of Matter

- Sulfuric acid
- Crystallography
Team Final Answer Poster
Decide who will do what job. Each team will need a Facilitator, a Reporter/Recorder, and a Materials Manager. If there's 4 people on your team, have the additional person be the Team Captain.
Be sure that each person gives input to what the final answer is and how it should be presented.
As a team, create a poster that explains the answer to our question: "Why do onions make us cry?" Be sure to use science words.
You will have 20 minutes to discuss your answer and make the poster. From there each team will present.
