  1. Fun and Easy Food Science Labs For the Busy Ag Teacher

  2. Why Food Science? • Expanding value added products industry • Ties into multiple subject area standards • Ties concepts into things students relate to • Adds excitement to your lessons • Labs can be easily adapted to basic or complex curriculum

  3. DNA Extraction Lab - Materials • Material with DNA • Detergent (ie. Dish soap) • Enzymes (Meat Tenderizer, Pineapple Juice or Contact Lens Solution) • Isopropyl Alcohol (70 or 95%) • Cold Water

  4. DNA Extraction Lab - Materials • Ziploc Bags • Test tubes • Wooden Sticks • Pipettes or eyedroppers • Measuring cups/spoons • Coffee filters and cups • Salt

  5. DNA Extraction - Procedure • Step 1 – Measure out a ¼ cup of your chosen material • Step 2 – Place material in ziploc bag and completely crush • Step 3 – Add up to a ½ cup cold water

  6. DNA Extraction - Procedure • Step 4 – Mix thoroughly • Step 5 – Strain through coffee filter into a cup • Step 6 – Add about 2 T of detergent and a pinch of salt (swirl gently)– let sit for a minimum of 10 min

  7. Gum Drop Lab - Materials • Jello • Sugar • Water • Pipettes or eyedroppers • Plates • Spoons

  8. Gum Drop Lab - Procedure • Step 1 – Measure out a portion of Jello powder on your spoon – Place on plate • Step 2 – Using pipetter add a few drops of water while mixing it into your jello • Step 3 – Add more water or Jello mix as needed

  9. Gum Drop Lab - Procedure • Step 4 - Form gum drop into desired shape • Step 5 – Roll in sugar • Step 6 – Enjoy!

  10. DNA Extraction Procedure • Step 7 – Add a pinch of meat tenderizer into test tube • Step 8 - Fill test tube 1/3 full of DNA/Detergent solution – (mix gently) • Step 9 – Hold test tube at a 45° angle

  11. DNA Extraction Procedure • Step 10 – Slowly fill test tube with an equal amount of alcohol • Step 11 – After the DNA has begun clumping harvest it with your wooden stick • DNA can be preserved in an alcohol solution for long term storage

  12. Sensory Lab #1 - Procedure • Step 1 – Obtain a small sample of each Kool Aid in a small cup for sampling • Step 2 – With your lab partner taste your first sample and try to determine what flavor it is. Record your observations and flavor guess

  13. Sensory Lab #1 - Procedure • Step 3 – Cleanse your tasting palette with water • Repeat steps 2 and 3 for each sample of Kool Aid

  14. Plastic From Corn Lab - Materials • Corn Starch • Water • Cups • Spoons • Optional – corn oil and microwave

  15. Plastic From Corn Lab - Procedure • Step 1 - Add a spoonful of cornstarch to your cup • Step 2 – Add an equal amount of water to your cornstarch and mix • Plastic should be the consistency of thick glue • Step 3 – Add more water or cornstarch as needed

  16. Plastic From Corn - Procedure • Step 4 – Check the surface tension of the mixture • Step 5 – Pour mixture into your hand and try to form it into a ball – Once formed observe how it reacts to the heat of your hand • Step 6 – Have fun with your plastic carefully observing how it moves between a liquid and a solid

  17. Sensory Lab # 2 - Materials • Glass or Plastic Vials • Various samples of food extracts and spices taken from the Food Science and Technology CDE list

  18. Sensory Lab #2 - Procedure • Step 1 – Obtain a sensory sample set for your group • Step 2 – Take sample #1 and record its color, texture and what you think the sample is made of • Step 3 – Continue until all samples are observed
