This lesson is designed to occur as part of a Nutrition and You Unit.
Before engaging in this lesson students learn, through inquiry-based strategies, about
This lesson consists of two parts:The characteristics of the nutrients-fat, protein, and carbohydrates. The health benefits of each nutrient. The risks of consuming too much of each nutrient. Units of measure – gram as unit of mass and calorie as unit of energy.
What am I Eating? Does it Matter?
Spreadsheets: Know your Nutrition Numbers
After this lesson, students will revise their daily food choices to meet the USDA recommended daily allowances. Then, as a culminating authentic unit assessment, students will collaboratively create a meal plan for their family that meets the USDA recommended daily allowances and accounts for family members’ tastes and dietary needs.

WHAT AM I EATING? DOES IT MATTER?
|
Objectives: Students will:
|
This lesson will encourage
students to become more aware of the nutritional needs of their bodies.
Students will:
1) Create a personal data sheet of food and drink consumed within the past 24
hours.
2) Students will refer to Use the
Nutritional Analysis Tool website http://www.nat.uiuc.edu/mainnat.html
to discover the nutritional contents of the food they ate.
3) Students will enter the amount of fats, carbohydrates, proteins and calories
into an Excel Spreadsheet.
4) Each student will calculate the amount of each nutrient they consumed within
the 24 hour period and create a chart (or graph) using this
data.
5) Students will use the following websites to compare their diet to what
is recommended, looking at servings, the food pyramid and dietary
recommendations: http://www.pueblo.gsa.gov/cic_text/food/food-pyramid/main.htm,
http://www.health.gov/dietaryguidelines/dga2000/document/choose.htm
6) Students will discuss their discoveries, reactions and questions and be prepared to answer questions.

A LESSON IN USING SPREADSHEETS TO KNOW YOUR NUTRITION NUMBERS
For this part of the
lesson, you will apply what you have learned about nutrition to determine how
balanced YOUR diet is. You will do this by creating and using a spreadsheet.
You will make and use an
Excel spreadsheet to track the food you have eaten for the last 24 hours.
Open up Excel on your
computer.
|
Before we begin you may want to learn a little about spreadsheets and
Excel, the software used to create one. A
spreadsheet is set up like a big table. The
rows, go across, and are numbered. Columns
go down, and are labeled with A,B,C’s. Each
box that is created when a row and column come together is called a cell.
In the example, cell B3 says “car loan”. |
Here is a link to a
site with tutorials on various parts of using Excel to create
spreadsheets. You may not need to use it, but if you need more help, here
is the address. |
Set up and label COLUMNS |
You will be typing
LABELS for the columns. When it says, “Food Eaten” with quotations
marks around it, type those exact words; do NOT enter the food that you
ate yet. Put your cursor in
cell A1, click and type Your Name, then press enter. |
Set up ROWS and
enter data into CELLS. |
Now, Put your cursor
in cell B2, click and type in one of the foods you ate for breakfast
today, then press enter.
Enter the appropriate
numbers for that food item in each of the corresponding cells B2-I2. Continue doing this
for each food you have eaten today, using a new row for each food and
being careful to select the correct serving size. |
Use SUM to
calculate the total for each column. |
When you are finished
entering the food for the day, begin a new row. We will call it “(x)” because we don’t know how many
foods you ate. (If you ate 20, it would be row 21.) Put your cursor in
cell A(x), click and type “My Total” then press enter.
It looks like a
weird, triangular E in the bar at the top. When you do this, the
numbers in that column should be included in an area outlined with a
dotted flashing line and the cell will say = SUM (D2:D”x”). Hit enter.
Repeat the procedure
for columns E through I. (Substitute
the column letter for column you are working on.) For tutorial see http://www2.nau.edu/edtech/newtutorials/excel/sum/sum.html |
Preparing
information for comparison to recommendations and for graphing. |
Now make a row (y),
under row (x), that starts with “total recommended”. To do this, click
in cell A(y) and type in “total recommended”. To find the total
recommended for your age and gender, go to the nutrition web site. When
you find the appropriate amount for each nutrient, enter it under the
appropriate column in this new row you just created (y) or total
recommended. So, the recommended
number of calories for your age and gender will be in cell H(y). |
Writing formulas
to Figure Percents |
Next, you will
calculate, for each nutrient, what % of the total recommended amount you
had for the day. You will do
this in row (z), which is right under row (y). First label the row by
clicking in cell A(z) and typing “% of recommended”.
To calculate percent,
start by clicking in cell D(z), or cell
D of your % recommended row, to calculate the % fat you ate today.
When you do this, you
will see a green checkmark appear. Click in cell D of
the row you labeled “my total”, to start with the total fat you ate
for the day. Next, add the “/”
(for divide sign) after the number you see in the white box. Do this by
typing the forward slash key on your keyboard or the divide key on your
numbers keyboard. Next, click on cell D
of the row you labeled “total recommended” D(y). Type in a $ sign right
after the “/” mark and before the last number you see, which
will be D(y) in this case. Click
OK. Repeat this process
for each column E-I. See a tutorial on how
to do this and how to format the cell for %. http://www2.nau.edu/edtech/newtutorials/excel/percent/percent.html |

Make a Chart (or graph) - Use either set of directions to make a chart in Excel |
|
These directions result in a quick chart added to the spreadsheet. |
These directions result in a separate object that can be placed in another document. |
Make a chart
comparing the amount you consumed to the recommended amount
for each of the nutrients. While holding the
“control” key –lower left on the keyboard-down, highlight the 2
boxes with your totals for the column you want to graph. So, if you are
graphing calories, you would highlight H (x or my total) and (y or total
recommended)
You will see a choice
of pictures for possible charts and graphs. Choose the one you like. I chose the
second one down on the left to get 3-D bars.
Click next, and next
again. The chart wizard will
ask you to add a title. Choose a title that describes the column you are
graphing (i.e. “calories” or “fat”) Click on the tab at
the top that says legend. To remove the legend, click where it says
“show legend”. You will see the legend disappear. Click on the tab that
says, “data labels” and click on “show value”. When you are
finished, click on “finish” and your graph should appear on your
spreadsheet. |
Using Microsoft Word and EXCEL: Select Chart from the INSERT Menu.Select the type of Chart you want to be inserted by clicking on it. Once you have made your selection, click the NEXT Button. Select the data that is to be included in the Chart by clicking the icon located in the right corner of the Data Range Field. This will minimize the size of the Source Data window to display the work sheet. You will select the data by clicking and dragging until you have selected all the relevant data. Click the NEXT Button located at the bottom of the window. Now label some of the items. Click on your chart so the handlebars appear. Go to CHART and choose CHART OPTIONS. Pick axes. Label the x axis “Actual Calorie Intake vs Recommended”. Label the y axis as “Calories”. Pick labels. Make an appropriate title. To change colors of your chart, Choose FORMAT, then on the drop down, choose CHART OBJECTS, then choose FORMAT CHART AREA. You may now select the colors for your chart. You may then print it out.
