A Donut Investigation

🔓 This is an unlocked sample! Byrdseed.TV is open for new memberships through May 31st, 2024. Join today!


Students will investigate the intriguing question: does a donut or a salad have more sugar? Using an image from an article, they'll determine if the photo is true or misleading, how they might add to it, and how they could create their own version.

Students will use the big idea "limited facts can lead to the wrong conclusions" to guide them in this investigation.

My findings (these may change over time):

Here is the original article.


  1. Students rank how much they trust the donut image.
  2. Then they check the math, using ratios to determine if the original image is accurate.
  3. They choose three new food items to compare, looking up the sugar content, then creating donut ratios for each.
  4. Finally, they redo the original image, choosing a new nutrient to use as the comparison.
  5. Students will update their original belief of how much they trust the image.
