Skill B: Observing, Measuring and recording
Title: To find out which foods contain starch and fats.
Apparatus: liquid cooking oil, paper towels, cooked egg white, iodine solution, cooked bacon, raw potato slice, medicine dropper, potato chip, cheese, bread, brown paper bag.
Method
1. Open a brown paper bag and cut it in half. Mark one part FAT and the other part STARCH. 2. Mark off each half into six sections. Label each section with the name of a food to be tested. 3. Place a small drop of cooking oil in the corner of the paper marked FAT. Hold the paper up to the light and observe the spot. Foods with fat leave a grease spot like this on brown paper. 4. Predict which test food contain FAT 5. Rub each food on its labeled section of the brown paper and let the spots dry. 6. Hold the paper up to the light source. Record the results from the fat test. 7. Predict which foods contain starch. Foods that contain starch turn dark-blue/blue black when iodine solution is dropped on them.
CAUTION: Iodine is poisonous and will stain clothing. 8. Place foods on the labeled sections on the STARCH paper. Place a drop of iodine solution on each food on the paper. Observe for color change. Record your observations.
