Which is bitter? CaffeineMaltose http://nsdl.org
You can do this in your classroom Using JCE DLib you can find two different molecules and ask students to point out similarities, or differences. Molecules can be rotated to show similar views of each. Space filling or ball-and-stick can be shown. SucroseMaltose http://nsdl.org
Cells in the mouth have different taste receptors G-protein-coupled receptors Sweet Bitter Umami Ion channels Salty Sour lllustration by William Oldham Taken from: http://www.vanderbilt.ed u/vicb/Articles/LensSum mer2005/WhereAreTheN ewDrugs.htm Work by Rod MacKinnon Taken from: http://www.nsls.bnl.gov/newsroom/science/2006/01- MacKinnon.htm
Activity: making mock applesauce Need : –Cup –Crackers –Water –Sugar –Cream of tartar (or lemon juice) http://nsdl.org
Are you planning to do the activity along with us? A.Yes B.No C.Maybe http://nsdl.org
Try this Crumble 1 or 2 crackers into a dish Add 2 tsp water Add 1 tsp sugar Add 1/8 tsp cream of tartar (or lemon juice) Stir and taste http://nsdl.org
How do these ingredients simulate applesauce? Sweet (sugar) Sour (cream of tartar) Juicy (water) Texture (crackers) http://nsdl.org
Safety Matters All JCE classroom activities include safety considerations. For this activity make sure not to use lab equipment or perform the activity in a lab! http://nsdl.org
Variations Lemon juice or citric acid instead of cream of tartar Try adding cinnamon or nutmeg Use different crackers, saltine vs butter crackers Add vanilla flavoring
Extension: Bake a mock apple pie and a real apple pie Use the best filling recipe from the students Have a taste test, see who can tell the difference. Frozen pie crust works great!
Which one (or two) do you think was made with real apples? 13 24 http://nsdl.org
Mmm, tastes like cherry! Artificial flavoring is big business. http://nsdl.org
Artificial flavoring Cheaper Purer and safer Often tastes just as good Active flavor is often chemically identical to the natural flavor Vanillin: artificial vanilla flavoring, taken from JCE DLib http://nsdl.org
Which product uses artificial flavor? http://nsdl.org
Another activity to try in class -sugar -vanilla extract -cinnamon -lime juice -club soda Have your students make cola using these ingredients: If you search for taste on the JCE index you will find more classroom activities and useful articles!
Chemical Education Digital Library (ChemEd DL)… is starting with resources from the JCE DLib, building on resources from the ACS Education Division and ChemCollective project, and will grow from there.
