Chew the FatNorth Carolina Science Olympiad, Elementary Grades

Event Leader Directions:Chew the Fat is three topics broken down into six activities:

1. MyPlate – 1 activity2. Food Labeling – 2 activities3. Digestive System – 3 activities

Setting up the event:Event leaders should set up:

1) Desk space for every team with the following items.a. Test packet.b. Calculator (Food labeling activity)c. One roll of toilet paper (Digestion activity)d. To minimize the amount of equipment need for the event, event leaders will set up 1

hands-on Digestion station (for toilet paper activity) and 1 hands-on MyPlatestation at easily accessible places in the room.

MyPlate Station - Bring package with nutrition fact label and/or whole food.i. 2 vegetable

Suggestion:a. Broccoli frozen with sauceb. Fresh broccoli

ii. 2 fruitSuggestion:a. Heavy syrup canned peachesb. Fresh peach

iii. 3 grainSuggestion:a. Brown riceb. Regular noodlesc. White bread

iv. 3 dairySuggestion:a. Skim milkb. Whole milkc. Ice cream

v. 3 proteinSuggestion:a. Beansb. Chicken nuggetsc. Hotdog

Coordinating the event:

Student teams entering the event should sit at individual team testing stations. Once everyone is seated, event leaders should read the following directions:

1) Teams should keep their eyes and ears on their own papers and activities.2) Each team should have the following at their desk.

1. Test packet2. Calculator (Food labeling activity)3. One roll of toilet paper (Digestion activity)

3) Test packets are in the following order.1. MyPlate – 1 activity2. Food Labeling – 2 activities3. Digestive System – 3 activities

4) Go Long!andMyPlate will require that teams get up and move to stations to complete activities. The event leader will let you know when it is time for your team to go do the go to the Go Long!andMyPlate station.

5) When selected, stop what you are doing at your desk.6) Take your test packet and move to the Go Long!station and then the MyPlatestation.

1. Only do the hands-on activity while you are at the station.2. Move quickly as other teams will need to follow.3. If the task takes you longer than 4 minutes, event leaders may ask you to move on to the

next station.7) When you have finished with both stations, return to your seat and keep taking the testing.8) Before turning in the test packet to the event leader, make sure your team has completed all tasks and

all questions.

Congratulations! You have completed Chew the Fat.

Scoring the event:1) Attached to this sheet will be an answer key.2) For easy scoring of the toilet paper digestion activity, have a piece of yarn already measured to

the correct length to compare to the toilet paper that teams leave on their desk. Score students by ranking them 3 = Correct (within a foot), 2 = close (within 2 feet), 1 = somewhat correct (within 3 feet), or 0 = not close or incorrect.

Final scoring will rank the team in accordance with Science Olympiad rules.

Activity 1:What’s on MyPlate?MyplateNorth Carolina Science OlympiadWhile all foods can be part of a healthy diet, using the foods provided by the event leader, make a healthy plate. Once you have picked the “best” or “most healthy” foods for each group, record the name of the food in the correct space on the plate.

Return to your desk.

Activity 1:Getting Your Facts StraightFood LabelingNorth Carolina Science OlympiadYou will compare the Nutrition Facts labels on two different snack food labels below.

After looking at the names of the snacks provided, predict which snack you think is the best option and why.

Prediction: ______________________________________________________

1. Classic Potato Chip 2. Baked Potato Chip

A. Working with labels1. Draw a circle around Total Fat on each nutrition facts

label.

2. Draw a square around Saturated Fat on each nutrition facts label.

3. Draw a triangle around Sodium on each nutrition facts label.

4. Draw a star next to the nutrition facts label with the most fiber.

B. Wrap it upUse the nutrition facts labels to complete the chart below. Draw an “X” next to the best answer.Which snack is the best option if you wanted to:

Snack 1 Snack 2

Reduce Total Fat Intake

Reduce Saturated Fat intake

Reduce Sodium intake

Increase Fiber intake

C. Check your predictionCircle one

1. Look at the chart above. Is there 1 snack that has the lowest total fat, saturated fat, and sodium? YESNO

Activity 2:Learning From Your LabelsFood LabelingNorth Carolina Science OlympiadYou will read the Nutrition Facts labels below to find the following:

1. Total Calories: 1. 2.

2. Total Carbohydrate(grams):

1. 2.

3. Total Fat(grams): 1. 2.

1. Classic Potato Chips 2. Baked Potato Chips

Next, you will calculate the calories from saturated fat for each label. Use the grams of saturated fat found on the food labels.

Hint: Saturated fat is a type of fat. There are 9 calories for each gram (9:1) of fat.

Example: 5 grams fat = 5 x 9 = 45 calories from fat

Label 1.____________x___________

Label 2.____________x___________

Which product has more calories from fat?

Lastly, you will calculate the calories from sugar for each label. Use the grams of sugar found on the food labels.

Hint: Sugar is a type of carbohydrate. There are 4 caloriesfor each gram (4:1) of carbohydrate.

Example: 6 grams sugar = 6 x 4 = 24 calories from carbohydrates

Label 1.____________x___________

Label 2.____________x___________

Which product has more calories from sugar?

Activity 1:Go Long!The Digestive SystemNorth Carolina Science Olympiad

You Will Need:Measuring Tape Toilet Paper Roll

How long is the gastrointestinal (GI) tract of a living adult human man? You will test your intestine knowledge with the help of a toilet paper roll!

Follow these steps:1. Take a roll of toilet paper and place it on the floor.2. Roll out the toilet paper until you think it has reached the

length of a living adult human male (GI) tract.3. Break off the portion of toilet paper you just unrolled.4. Take the measuring tape and measure the length of the

toilet paper in feet and inches.5. Write this measurement in the chart below.

Intestine length ______feet_______inches

Who has a longer gastrointestinal (GI) track

You or an adult and why?

Activity 2:Food Crushing FunNorth Carolina Science OlympiadCorrectly label the digestive system using the following organs:
