1. Which aromas gave you the most difficulty? Which aromas gave your classmates the most difficulty? Sarah had difficulty with Austin Choco cremes. Taryn had difficulty with the tuna and chili.

2. Which food was most often identified correctly? Ravioli, green beans, tuna, chili, hot salsa, tomato paste, lays, granola bar.

3. Why did some students have more difficulty than other students with this task? Some people have a better sense of smell than others.

4. Were the responses of the second member of each pair more or less accurate? Yes because we already knew the smells.

5. Is taste or aroma more important in food identification? Explain your answer. Smell is more important because if something doesn't smell good you don't want to eat it.

How many taste buds do you have? Are you a "super taster?"

Areas of the tounge (above) and what flaovors they taste!

Work'in hard!

Sensory Preferences

1.  Describe a negative experience you remembered about one of the foods you listed as a least favorite.
Sarah= I got sick after eating turkey.

Taryn= It was when we had a salad and I asked what this pink thing was and I had it in my mouth and my mom said it was a radishes. So I spit it out and I've never touched one since.

2.  Describe a negative experience your parent or guardian remembered about one of the foods he or she     
     listed as a least favorite.
Sarah= My mom got sick after eating Mexican food.

Taryn= It was when my mom and I were getting subway on the way home from a softball game and she asked if she could get a little bit of peppers on the sandwich and when she ate it she spit it out and never ate jalapeno peppers again.


3.  Which of the least favorite foods listed above would you not be willing to eat as an ingredient in a
     combination dish, such as a casserole or soup?
Sarah= It would be turkey i got sick after eating turkey soup.

Taryn= I would never use mushrooms and white onions.


4.  Which of the least favorite foods listed in question 3 would you not be willing to eat even if it were
     prepared in a new and interesting way?
Sarah= I would not use mushrooms.

Taryn= I would still never use mushrooms.


5.  What similarities and differences did you discover between your most and least favorites and those of
     your parent or guardian?
Sarah= My mom likes chocolate and I like chocolate My mom likes mushrooms and i don't like mushrooms.

Taryn= I don't like mushrooms but my mom does. My mom like chocolate cake and so do I.


6.  In what ways do you think your family affects your food preferences?
Sarah= When my sister or mom adds mushrooms to the food I like but i ask them if they can take some of the dinner out and not put the mushrooms in there.

Taryn= If they added mushrooms to everything I wouldn't eat the dinner so I would make my own dinner or have my mom save me some dinner without the mushrooms.

Biscuits using metric measurment and massing....

Purpose: To measure mass using the Metric System.

Procedure summary: (what did we do?) We used the cooled biscuts that we made and baked to see how much mass was really in the biscuts. To do the measurement we used a metric scale and thats how we got the mass of the biscuts.

Lab Data:
Mass of Biscuits: The mass of the biscuts were 105 grams.

Initial volume of rice in graduated cylinder B: The volume of the rice in graduated cylinder B was 812 grams.

Volume of rice remaining in Graduated cylinder B: There was 663 grams left.

Total volume of rice and biscuits in graduated Cylinder A: All together we had 250 grams in Cylinder A.

Volume of rice used: The amount of rice that we used was 149 grams.

Volume of biscuits: The volume of the biscuts that we had were 101 grams.

Calculate the density of the biscuits (density= mass / volume): 105/101=1.04 grams

1. What was the average density of your biscuits? The average density of our biscuts was 1.04 grams.

2. Which is a more accurate measurement: mass or volume? Why? The answer is mass. It was eaiser because it has less chances for a mistake.

3. How would you measure the volume of an irregularly shaped object in water? 1= measure volume of water in graduated cyclinder. 2= put the object into the water. 3= We would record the volume of both. 4= subtract the volume of the water from the total volume.

4. What relationship is there between density and texture of the biscuits? Big, fluffy biscuts would have less density because they have more air in them.

5. Which ingredient in the biscuits is related to density? Yeast or another leavening agent.

Metric System of measurement

Prefixes:

Centi- is 100 times smaller than the base unit.

Deci- is 10 times smaller than the base unit.

Kilo- is 1,000times more than the base unit.

Milli- 1,000 times smaller than the base unit.



Base Units:
Mass = Grams in the Metric System and Pounds in the English system.

Volume = Liters in the Metric System and Gallons and cups in the English system.

Temperature = Celsius degree in the Metric System and Fahrenheit degree in the  English system.

Length = Meter in the  Metric System and Feet in the English system.

WOW! Sarah is so smart! I love it! Ms.Turner!

Balancing Chewing Gum

Purpose: We will practice using mass and the electronic balance.

Which type of gum had a greater loss of mass after chewing? Why?
Regular gum lost more mass because it has sugar.
What substance cause the loss of mass during the chewing?
The sugar.
Was there a difference in the texture between the two types of gum?
Sugar was harder than the regular gum because it has sugar in it.
Given that sugar has 4 calories per gram, how many calories would you estimate are in a stick of gum?
8 times 4 = 32 calories
How would you determine the mass of 10ml of milk? We would put it in a lightweight container than we would use the electronic balance to mass the milk. Than we would have to subtract the mass of the container!
