Grade 7Science6 days
5.0 (1 rating)
In this project, 7th-grade students investigate the health risks associated with processed foods, such as candy and chips, and develop strategies to promote healthier eating habits within their community. Students identify ingredients and chemical additives, compare how the body processes processed versus whole foods, and propose mitigation strategies. The project culminates in a community health campaign or nutrition guide designed to educate and encourage healthier choices.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

Ingredient Investigator: Unmasking Processed Foods

Students will select a processed food item (candy, chips, cookies, ramen, hot pockets, etc.) and identify up to 5 ingredients. They will then research the purpose and potential health effects of each ingredient, using provided reliable online resources. For example, if a student chooses a Snickers bar, they might investigate ingredients like high fructose corn syrup, chocolate liquor, or soy lecithin.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Choose a processed food item (candy, chips, cookies, ramen, hot pockets, etc.). Find the food label online using websites like Open Food Facts (https://world.openfoodfacts.org/) or the product's official website.
2. Create a list of up to 5 ingredients.
3. Research each ingredient to determine its purpose in the food item, using websites like the FDA (https://www.fda.gov/) and the USDA (https://www.usda.gov/)
4. Investigate the potential health effects (positive or negative) of each ingredient using reliable sources such as the National Institutes of Health (https://www.nih.gov/)
5. Using molview.org, draw the chemical structure of each ingredient.

6. Research and describe the roles of the liver, pancreas, spleen, and gallbladder in the digestion process, and how these organs might be affected by the 'suspect' chemicals.
7. Create a simple diagram or flowchart illustrating the breakdown process, labeling the food components, the digestive organs involved, the locations of physical and chemical changes, and the potential negative impacts of the 'suspect' chemicals.

Final Product

2. Research the health risks associated with overconsumption of processed foods (e.g., diabetes, obesity, heart disease). Use reliable sources such as the CDC (https://www.cdc.gov/), the NIH (https://www.nih.gov/), and the American Heart Association (https://www.heart.org/).
3. Select 2-3 specific health risks to focus on.
4. For 3-5 of the ingredients of your processed food, research if they affect any specific organs or organ systems, other than the digestive system (circulatory, nervous, immune, muscles, skeletal, respiratory, endocrine, excretory). Include a brief summary of each system's function (circulatory, nervous, immune, muscles, skeletal, respiratory, endocrine, excretory) and the organs in that system.
5. Calculate how many servings of your chosen food item would exceed the daily recommended limits for sugar, fat, or sodium based on a 2000-calorie diet.
6. Find statistics on how many people in the USA have the 2-3 diseases selected in Step 3, using websites like the CDC (https://www.cdc.gov/) and NIH (https://www.nih.gov/)

Steps

Here is some basic scaffolding to help students complete the activity.
1. Review all the research and notes gathered from previous activities in this project, focusing on key findings related to the health risks of processed foods and the benefits of whole foods.
2. Identify the single most important message about healthy eating that you want to communicate to your target audience (students in the cafeteria or members of your community). This could be about reducing sugar intake, increasing fruit and vegetable consumption, reading nutrition labels, or any other relevant topic.
3. Decide whether you want to create a poster for the school cafeteria OR a brochure to share with someone you care about. Consider which format will be most effective for your chosen message and target audience.
4. If creating a poster: Brainstorm visual elements (images, charts, graphs) that can quickly and effectively convey your message. Develop a catchy slogan or title to grab attention. Plan the layout of your poster, ensuring it is clear, uncluttered, and easy to read from a distance.
5. If creating a brochure: Organize your information into logical sections or panels. Use headings and subheadings to guide the reader. Consider including a personal anecdote or story to make the information more relatable. Plan for actionable tips that the reader can easily implement.
6. Design and create your poster or brochure, paying attention to visual appeal, clarity, and accuracy of information. Use reliable sources to support your claims and cite them appropriately.
