1 Chemistry 151 Chemistry and Health (from an elementary school perspective)

2 Food

3 Macronutrients: needed in large amounts Micronutrients: needed in smaller amounts  Carbohydrates  Proteins  Fats  Vitamins  Minerals Molecular Components of Food

4 2010: Nutrients Activity Who Stole the Playstation? Students will understand the basic concepts of different nutrients in foods. Students will chemically test and compare different nutrients using extraction techniques. Students will observe the presence of various nutrients in foods.

5 We have been called in by Colby’s Security Department to help them recover a Playstation 3 (PS3) that was stolen from their office. The PS3 was removed at approximately 9:00 PM while the officer on duty was called away from a game of Grand Theft Auto to investigate a potentially illegal gathering in one of the residence halls. The officer noted five suspicious persons on his way out of Roberts. Fortunately, the culprit left behind a clue in the form of a crumb of food. We will conduct an analysis of the snack food eaten by each suspect to try to match it to the culprit’s crumb. Note that we will also analyze a donut as a control to make sure that the crumb wasn’t left behind by the security officer himself.

8 2010: Nutrients Activity What is a pirate’s favorite drink? Students will understand the importance of micronutrients to protect against diseases like scurvy. Students will test various beverages for vitamin C content.

9 DNA High tech: purify from cheek cells, amplify using PCR Low tech: purify from strawberries or other source

10 2013: DNA Activity Determining Rh Factor Students use their own DNA as a template for PCR. Students determine whether their blood type is Rh positive or negative after analyzing the PCR products via electrophoresis.

11 2013: DNA Activity Determining Rh Factor Students use their own DNA as a template for PCR. Students determine whether their blood type is Rh positive or negative after analyzing the PCR products via electrophoresis.

12 2013: DNA Activity Determining Rh Factor Students use their own DNA as a template for PCR. Students determine whether their blood type is Rh positive or negative after analyzing the PCR products via electrophoresis.

13 2012: DNA Activity See your own DNA! Students purify their own DNA from a cheek cell sample.

14 2010: Microbes Activity Do you know how fast microbes spread? One student is “infected” with yeast and then shakes hands with a classmate, who shakes hands with a classmate, and so on. Student then see if their hands were “infected” by inoculating a yeast growth plate.

15 2012: Fitness Activity Healthy Hearts Students use heart rate monitors under various conditions (at rest, after exercise, listening to music).
