Interest Approach or Motivator
Your local grocery store conducted a survey of their customers and found that customers want to know where their food comes from. The store has hired your team to create an augmented reality video that will be triggered by an image at the grocery store and tell the story of where that food product came from.
Background – Agricultural Connections
Augmented reality is a live direct or indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. Augmented reality overlays virtual information atop a real-world object. This process is similar to the way a mobile device scans a QR code and links to a website.
Most Americans are three generations removed from the farm and don’t always understand how their food is produced. They think that milk comes from the grocery store, and rarely consider the cow that produced it or the transportation or processing that it went through before it found its way to that store.
Here are some basic products that students may be familiar with but might not know where they come from.
Milk: Most milk in the U.S. comes from Holstein cows (the black and white ones). Dairy cows are milked up to three times each day and can produce as much as 9 gallons of milk a day. The milk is transported to a creamery where it is pasteurized to kill any bacteria. It is checked for quality and then chilled and packaged.
Eggs: Female chickens or hens can produce one egg about every 24 hours. The eggs are collected, washed and checked for quality in a process called candling before being packaged.
Spaghetti pasta: A special type of wheat called durum wheat is used to make pasta. The wheat is milled or ground down to flour. The flour is mixed with water and egg and then put through a pasta press that will make the correct shape and size of pasta. The pasta is left to dry and then packaged.
Bread: A type of wheat called hard red spring wheat is used to make bread. The wheat is milled or ground down to flour. The flour is mixed with water, milk, oil, and yeast. The bread is kneaded and rested multiple times allowing the yeast to create tiny air bubbles and allowing the dough to become somewhat elastic. The bread is then baked, sliced and then packaged.
Cheddar cheese: The milk from dairy cows is transported to a creamery and bacteria is added to it. The bacteria feed on the lactose turning it to lactic acid. Rennet is added and the milk splits into curds (solids) and whey (liquid). The curds are removed and pressed get rid of excess whey. The blocks of pressed curds are cut to size and shape and then packaged.
Chicken noodle soup (chicken): Broilers can be harvested at 7-8 weeks old. Once the bird is dead, the feathers are plucked and the skin removed. The meat is cut away from the bone. The meat can then be cooked, cut into small pieces, and added to other products like soup.
Tomato juice: Tomatoes are harvested by machine and transported to a plant by truck. The tomatoes are washed and then crushed to release the juice. Seeds and skin are strained out. The juice is pasteurized and then bottled.
Syrup: Many syrups (like pancake syrup) are corn syrup with flavoring added in the process. Yellow #2 dent corn kernels are dried, shelled and cleaned. Kernels are added to warm water with sulfur dioxide. The kernels are passed through a mill and then into a separator to remove the corn starch. The corn starch is mixed with a small about of hydrochloric acid and water to convert the starch into sugar. The syrup could be used at this point or have flavors or coloring added to it.
- Provide the core concepts and set context of the why of the assignment using the background information.
- Talk about the different store products and have examples of each to show students. Review different food items and the agriculture behind them.
- Teach basic use of app (have app preloaded on classroom iPads or allow students to use their own devices)
- Break class into teams of two. Have each team select a grocery store product. Ask each team to come up with a brief explanation/example of their grocery store item and the process needed to grow and turn the raw agriculture product into the final product and that helped put it on the store shelf.
- One partner will shoot a short video of the other partner explaining the grocery store item. Videos should not be more than 1 to 2 minutes long. Take a picture of the item or use a picture of the item. (if the picture is a close up of the product name or logo the aura will work scanning the picture or the physical object)
- Select the video they took from their camera roll to be applied as the overlay.
- When each partnership is finished, tape the picture of their item on the walls around the room or display the physical objects around the room indicating what the trigger image is.
- Allow students to take a walking tour of the room and using an iPad or smart phone hover the device above the picture. The student created video overlay will automatically begin playing and students will learn about the different products.

- Dairy cows are milked up to three times each day and can produce as much as 9 gallons of milk a day.
- Female chickens or hens can produce about one egg every 24 hours.

- Most Americans are three generations removed from the farm.
- Sales of natural, organic food and beverages have increased 20% from 2009 to 2012.
- More than half (56%) of the food and beverage product categories in the U.S. showed decreases in the average number of ingredients per product in the same period.
- Half of consumers get more cooking ideas online than anywhere else.
- Two-thirds of consumers spend more than 10 hours a week online and 63% of consumers surf the Internet on their smartphones.
- Only 34 percent of Americans feel the agriculture industry is transparent and only 30 percent feel food companies are transparent about food production practices.
- Once you teach the process students can use it to create other augmented videos for future lessons independently. Keep a board posted in the room to display the trigger images.
- Use image software to have students edit the trigger images to make them more professional looking.
- Use screen flow software and allow students to edit their videos, splice different pieces together and make a more professional looking video. This would likely take more time and would be suggested as a homework assignment.
- Have students present their video to the class and have the class go through the learning activity at the grocery store or in class using their smartphones to read the trigger images and access the subsequent augmented reality.
- Set up a class channel on Aurasma to keep Auras organized and saved.
