EXPERIMENT: Proper PattiesQuestionHow can you tell when a hamburger patty is cooked to a safe temperature? My Hypothesis:_________________________________________________________________ _________________________________________________________________ _________________________________________________________________ Materials Needed:
Procuedure1. Form a round, thick (1") hamburger patty. Measure and record the temperature of the patty 1 / 4" from the edge. (See chart below.) 2. Now, take the meat's temperature in the very center of the patty. 3. Place the patty on the toaster oven broiling tray. 4. Place the tray in the toaster oven and turn the dial to broil. 5. When the burger looks cooked on one side, have your teacher turn over to brown the other side. Remove it from the toaster oven. 6. Now take the patty's temperature 1 / 4" from the outside edge, and again in the center of the patty. This must be done quickly so the patty doesn't lose its heat! Record your temperature readings on the chart below. 7. If the temperature reading is not 160°F, place the patty back in the oven and then take the meat's temperature every two to three minutes until the temperature is 160°F in the center.
Thermometer Tips:
Did You Know?When a piece of meat is "ground up" to make hamburger, the bacteria that was on the surface of the meat can end up on the inside of the burger! That's why it's so important to cook the whole burger to a safe temperature of 160°F! My ObservationsWhen I measured the meat temperature 1 / 4" from the edge and in the center the first time, the outside of the patty looked: ____________________________________________________________ When the thermometer read 160°F in the center,
My ConclusionsThe best way to tell if the hamburger is done and safe to eat is to: ____________________________________________________________ ____________________________________________________________ It's important to wash the thermometer after each use because: ____________________________________________________________ ____________________________________________________________ When meat is cooked to 160°F, If hamburger is not cooked to 160°F, this is what could happen: ____________________________________________________________ ____________________________________________________________ What do you think? Does the color of meat tell you whether it is cooked enough to be safe to eat? ____________________________________________________________ ____________________________________________________________ Tell Your Family ...Check to see if your family has a food thermometer and uses it!
