A Moldy Fry
By: Valene Salas
General Characteristics: In my class, I have a total of twenty-two 5th graders that consist of
10 girls and 12 boys. They are ages 10-ll years and the socioeconomic status of most of my
students are from middle class families. I have a diversity of cultures in my class that
includes Filipino, Chamorro, Korean, and Caucasian. The students are very energetic and
hardworking. I have one student who is visually impaired, where he cannot see things so
small, but he is very active and does not let his disability stop him.
Entry Competencies: Introduce the topic on Nutrition and the types of foods that taste good
but are actually bad for our health by asking the students to compare the prices, weight, and
the amount of French fries given by three different food establishments (McDonalds,
Wendy’s, and Burger King). This is a good opportunity to discuss the Food Pyramid and the
topic of obesity and the reasons for obesity and what could lead to health problems. The
students have little experience gathering information and interpreting data. They have had
exposure to computers and excel due to computer classes, but they never really used the
computers to assist in their research.
Learning Styles: Most of the students in my class are excellent in Math and Science. Most
of my students are kinesthetic learners and visual learners. Two to three are auditory and
textbook oriented where they could read and answer questions on quizzes and exams. Most
of my students like to work independently, but they enjoy working in groups when it comes
to projects. Their math scores are high and their reading level is just above average.
1. Students will be able to make predictions of which French fry would mold faster by
formulating a hypothesis
2. Students will obtain knowledge of how fast foods could lead to health problems by
observing different french-fries from different fast food restaurants
3. Students will create a spreadsheet of the number of days it takes a specific French
fry to mold by inputting their data in excel.
4. Students will analyze their results by creating a chart in groups of 4
5. Students will present their findings by creating a poster board( title of science project,
hypothesis, materials, charts, etc)
Select Media, Materials, and Methods
2. Documentary “Super Size Me”
4. French Fries (McDonalds, Wendy’s, and Burger King)
5. Zip-loc bags (plain white and clear)
6. Paper Towels
8. Microsoft Word and Excel
Show a documentary titled “Super Size Me” to the students. After watching the
documentary, the students will predict which French fry will mold faster. The students will
then get into groups of 4 or 5. The teacher will distribute the French fries into the 5 groups
(1 McDonalds, 1 Wendy’s, and 1 of Burger Kings Fries for each group).Using the given data
sheet, that serves as their outline, they will have to input their data of the compared prices,
the amount in each order of fries, and the weight of the fries. Each group would then have a
chance to create a spread sheet in their computer classes and input data once a week. The
computers in the computer class would serve has the chosen software to use for their data
Utilize Media, Materials, and Methods
• Get students into groups of 4 or 5. Distribute one batch of fries from each
establishment and give it to the groups. The students will put the fries into
separate plastic Zip-loc bags with labels and observe the changes for 2
months, but observe the bags every week.
• Using Microsoft 2007, have the students create a table of the data they
gathered (Prices, Amount of fries, and weight) But if time is an issue, create a
data sheet for your students.
• Click on the “table” icon and choose 4 rows across and 4 columns down.
• Label the top with Fast Food, Price, Amount of Fries, and Weight
• Label the left side of the columns Burger King, McDonalds, and Wendy’s.
• Students will then input their data from the given data sheet that served as
How many fries?
Require Learner Participation
Includes detailed methods for actively engaging all students for the lesson’s duration.
10 minutes- Introduction
Review the food pyramid and the healthy foods that we should include in our
everyday diet and the reasons we should include these foods into our diet
Talk about the issues on obesity, but first ask the students the meaning of obesity
and the causes of obesity.
Once their input has been given and gathered, ask if fast foods are healthy for us to
eat every day.
40 minutes- Exploration
Show a documentary titled “Super Size Me”. When finished watching the
documentary, ask the students questions about the documentary.
Group the students into groups of 4-5 and distribute the data sheet to each group
Then distribute the French fries and each group should have 1 batch of fries from
McDonalds, Burger King, and Wendy’s. Using the scale given to them they will weigh
each batch of fries and input their findings into the data sheet. The students will also
get the prices and predict how many fries they think are in each batch and the
actually count the batches of fries.
The students will then place each batch of fries into a clear zip-loc bag. Make sure
the bags are labeled.
McDonalds Burger King Wendy’s
Distribute another data sheet the students will use to observe the French fries at the
end of every week. Like shown above. The students will input their finding for the
first week and continue on for the next 2 months
20 minutes- The next day
Using a projector, show the students how to input their data into the readymade
table. Then have the students create their own table during computer class and have
them save it to your personal flash drive so you will be able to work it in class as well.
Using their own table, they will input their data of the price, weight, and the amount of
fries in each batch along with their predictions.
Have the students create a table again for their observations of the fries. After every
week, the groups will input their observations: 1-not moldy or brown, 2- brown, 3-
brown and soft, 4 brown, soft, and moldy. They could do this in their computer class
and again save their information on the teachers flash drive. Continue this for two
At the end of the second month, have the students input all their data and create a
After gathering their data, putting their information on tables and charts, the students
will create a poster board with their title, materials, methods, conclusion, and most
especially charts and tables.
A World of Fries
Each group will come up and present their poster and most especially their charts.
Each member of the group must have a part of the presentation
The teacher will then relate the student’s observations and results to how Fast Foods
are unhealthy if eaten a lot and that it will take longer for our bodies to digest these
foods which can cause weight gain and other health problems such as obesity.
Evaluate & Revise
The students were able to predict which French Fry would mold faster and which
would not mold as quick. They were able to create charts and tables that helped them
gather data. However, a few of the groups had a bit difficulty creating a chart in the
computer, but with a little guidance they were able to create charts easily. They just needed
to understand the icons, what icons to press, and where to find the icons. After inputting
their data into their tables and charts, the students were able to justify their hypothesis that
McDonalds fries would take longer to mold than the Burger King and Wendy’s fries.
As for the presentation, several students in the group played a vital role in presenting
their charts and basically their finding. For teachers grading purposes, a rubric was
conducted to grade the students as a group and how well they worked together.
The rubrics below are based on the completion of the project from each group and
the structure of the chart which will help me as a teacher evaluate their understanding of the
