Unit Summary
Life is more hectic than ever -- between school, sports, and friends. Very few have the time to think about what to eat. We often wonder whether we eat to live or live to eat. The answer to this question decides our eating habits. However, the lifestyle of many people suggests that we live to eat. Our modern lifestyle has brought a dramatic change in the eating disorders. There has been an alarming increase in obesity worldwide. Earlier, obesity was just linked to adults but now it has engulfed children. Statistics show that about one in ten children in Asian countries suffer from obesity. This has become a concern to all, and various ways and means are being taken to reduce the number of cases of childhood obesity.
In this unit, student nutritionists of school, investigate the eating habits of their peers by conducting a survey. The students work in groups with an aim to create awareness about childhood obesity in the school community and propose feasible strategies to prevent and control obesity. They plan a balanced diet for their peers and present their study through wiki. As a culminating activity, the young nutritionists create flyers to generate awareness about balanced diet and distribute them during the Eat Healthy, Stay Healthy Campaign.

Assessment Processes
View how a variety of student-centred assessments are used in the Eat Healthy, Stay Healthy Unit Plan. These assessments help students and teachers to set goals; monitor students’ progress; provide feedback; assess thinking, processes, performances, and products and reflect on learning throughout the learning cycle.
Instructional Procedures
Prior to Instruction:
Distribute the project newsletter (DOC 1.00MB) to parents and school community to explain the concept of projects in your classroom
Week 1: Getting Started
Pose and discuss the Essential Question, How can we lead a better life? Elicit students’ ideas and examples. Relate the discussion to the topic of healthy eating. Use the Food Nutrition Quiz* to tap students’ prior knowledge. Have students write notes and questions in their journals.
The Problem Scenario
Place students in groups of five. Explain the following situation using the project introduction slideshow (PPT 1.64MB).
Obesity was once associated with adults but now it is affecting children too. In the recent years, cases of childhood obesity have increased significantly. Your class has been asked to work as nutritionists to create awareness about childhood obesity and propose feasible strategies to prevent and control obesity in the school community.
Introduce the Unit Questions:
- How do I plan a healthy and nutritious balanced diet?
- How do I prevent and control obesity in my school community?
Explain to students that they will be exploring these questions throughout their work on the project. Distribute the To-Do-List (DOC 297KB) to help students self-assess their own progress.
Homework Assignment: Ask students to refer the list of websites (DOC 28.5KB). Ask them to think about the following Content Questions while they are researching and to take notes to prepare for the upcoming class discussion.
- What is food pyramid?
- What are the classes of food?
- What are their functions to the body?
- What is obesity?
- What is Body Mass Index (BMI)? How to calculate it?
Covering Nutrition Basics
Introduce the Discussion Rubric (DOC 87KB) to the students. Explain to students that the project requires them to participate in a number of discussion activities using the online discussion board. Yahoo! Group*, ezboard* and phpbb* are the tools for setting up the online discussion platform. Review the different criteria such as “Engagement, Interaction, Collaboration and Reflection”. Highlight the key points of each criterion and stress the importance of using the rubric as a scaffold to help students benefit maximum from the discussion sessions.
Students discuss their research findings using the online discussion board. Have the appointed moderators to monitor the group discussions. Remind students to review the discussion rubrics and the online discussion guidelines (DOC 54KB) before they start their discussions. Support the students by giving your inputs on nutrition basics.
Get students to present their understanding of the terms - food pyramid, obesity, BMI, etc. on posters for the class notice board. Encourage the students to make posters creatively by using drawing, photographs, etc.
Week 2: Conducting Online Survey
Inform students that survey is one of the important milestones of their project. Provide time for students to come up with some questions that they would like to investigate. Let students brainstorm in their groups and share their questions with the class. Compile a survey questionnaire based on suggested questions.
Introduce online survey tool for students to post their surveys. Surveymonkey* is an example of the online survey tools. Share with students the survey guidelines (DOC 43KB). Students identify sample classes in the school to conduct the online survey.
Analysis
Have students analyse the survey data in their respective groups. Arrange a session with the mathematics teacher for analysis of the survey data and presenting it in a graphic form. Provide time for students to do the analysis and plot the graphs. Review students’ work and provide feedback.
Sharing session
After the completion of the survey, make students sit in their respective groups and discuss their survey results. Ask them to note down their learning from the survey. Spend time with each group and monitor their progress. Encourage students to make connections between the data collected and the eating habits, family background, daily routine, etc.
Have students calculate the BMI of each student and categorise them in underweight, normal, overweight and obese students. Also, to make students realise the feelings of obese students – have an open discussion and share some case studies. Request students to empathise with the students and thus sensitise them about the problems of childhood obesity. Speak about the impact of obesity covering both the physical as well as the emotional aspects.
Introduce students to the Eat Healthy, Stay Healthy Campaign and ask for suggestions to make the campaign informative and interesting for the school community. Instruct students to collate their entire study, as they will start making their wiki in the next class. Ask students to brainstorm and discuss on the causes and effects of obesity on children. Pose the Unit Question again, “How do I plan a healthy, nutritious balanced diet?” Encourage students to conduct research for planning healthy diet to prevent obesity. Arrange for a session with a Dietician. Encourage students to clear their doubts regarding diet and obesity. Organise each group to have a face-to-face interaction with the Dietician and get them to share their plans for a healthy diet.
Week 3: Creating Wiki and Flyers
Introduce the assignment of creating a wiki*. Share the wiki rubric (DOC 41KB). Explain each criteria of the rubric. Ask students to make a story board of their wiki in a group. Review the story board and give comments. Emphasise that the wiki will answer the Essential Question “How can we lead a better life?” Schedule two to three days for students to work on this project and have meetings in-between to check on students’ progress.
Encourage students to make Eat Healthy, Stay Healthy flyer (PDF 337KB) for answering the Unit Question “How do we prevent and avoid obesity in our school community?” Describe the criteria in assessing the students’ flyer using Eat Healthy, Stay Healthy flyer checkbric (DOC 31KB). Provide two days for the completion of this assignment.
Week 4: Awareness campaign
Put the posters prepared by the students during the project on the school notice board. Send invitation letters to the parents, the dieticians for the Eat Healthy, Stay Healthy Campaign. Arrange for a hall where students will present their findings. The hall should be big enough to allow students to present simultaneously.
Allocate a session in which students would do a rehearsal on their presentations. Make all students in each group to participate in the presentations.
Arrange for the banner of Eat Healthy, Stay Healthy to be put up in the entrance of the hall. Put up the posters of the students in the hall. Have students share their wiki* and the diet posters to the audience. Make students distribute the Eat Healthy, Stay Healthy flyer (PDF 337KB) to the students and parents.
At the end of the project, as a culminating activity ask students to write their reflections in the journals.
