Preparation

1. Print and cut out the attached Source Search Pictures showing everyday items.
   • Optional: If you prefer to get your students involved in the preparation stage (and have time), have students collect their own pictures of every day items. Gather a variety of magazines or slick ads from the Sunday newspaper and instruct your students to cut out pictures that represent items they use regularly (food, cars, soap, clothes, computer, etc.) Avoiding duplication, select 36.
2. Randomly divide the 36 pictures into two groups. Use two colors of index cards (or card stock) and glue the pictures onto the cards. Laminate the pictures for future use.
3. Obtain four containers (boxes, plastic tubs, paper box lids, or paper grocery bags) and label each with one of the following: "Stores," "Factories," "Farms," and "Natural Resources."
4. Identify a suitable location for a relay race such as an area outside, a wide hallway, or the gymnasium.

Activity

1. Divide the class into two teams. Divide the laminated pictures by color. You should have 18 pictures in each pile. If you are using red and blue index cards, you will have a red and blue team.
2. Take the students to the location of the relay race and place each team in a single file line. Be sure to have all the pictures face down in front of the first person in each line. Locate the tubs 20-50 feet away from the lines.
3. Give students the following instructions: "This is the source relay. Your job is to place each card in the tub representing the original source of the every day item that is pictured. When you are in the front of the line, pick up a card, look at the picture, then run to and place the picture in the correct tub based on the product’s “source”– either “Stores,” “Factories,” “Natural Resources,” or “Farms.” Keep in mind that you are looking at the product, not the packaging. The next person in line goes when the person in front of them returns and crosses over the start line or hand-tags them. The returning player should go to the end of the line."
4. Ask students if they have any questions and clarify as needed. Begin the relay race and continue until all of the pictures have been sorted. The first team to finish the sort wins temporarily, but the ultimate winner will be determined by accuracy.
5. After the relay is over and the pictures are sorted, return to the classroom or have the students gather around you in a suitable location to go through the cards and discuss the correct answers. As you hold up each picture, the students can show whether they agree or disagree with the sort using the "thumbs up" or "thumbs down" signal, or another response as chosen. Use the attached Source Search Items Reference List for the correct answers and explanations for each card. You can also refer to the Source Search e-Learning lesson video for a recorded explanation. If you choose to keep score to identify a winner, tally the number of cards in the correct boxes for each team.
   • Farms: Explain that if the item contains ingredients or raw products from a farm, the item is in the correct box. Examples would be any food items such as cereal, cookies, and milk, or any clothing item made from a natural fiber such as cotton (jeans) or wool (coat). Some items from a farm that are not eaten or worn include paint (this contains linseed or soybean oil) or fuel such as ethanol. 
     • Note: After most relays, the “Farms” container will typically have only a few items in it.
   • Natural Resources: Explain that items in this tub should be products we get from the ocean, from plants or animals that occur naturally without management from humans, or from mining. Examples of items that should be in this box are cars, salt, water, plastic (plastic starts as oil, which is mined) synthetic fabrics (polyester, petroleum or oil products), computers, cell phones, and any metallic items. Fish or shrimp can be caught in the wild, but can also be farmed. Wood products may be in this box, but many wood products come from timber grown on farms. Let the class decide how to divide these. Remind your students that this is the “source” search. What is the “real” source of the things we use every day? Nearly all are grown or mined – farmed or extracted from the natural world.
     • Note: This tub is also likely to only have a few items inside.
   • Factories: Explain that a factory is a place where raw ingredients are changed into the useful items we need or want; wood into furniture, ore into steel for cars, wheat into bread, and potatoes into chips. A factory assembles items to later be sold in a distribution center or store. With this information, ask students, "Can factories be the original source of any items?" (No) Proceed by sorting every card in the “Factories” box into either the “Farms” or “Natural Resources” container. After doing this, your students should understand that all products were originally grown or mined.
   • Stores: Move to the box labeled "Stores." After receiving the explanation about factories, check for understanding by asking, "Are stores the original source of any items?" Students should realize that, like the “Factories” container, nothing should be in the “Stores” container. Stores are where we purchase items and are not their original source. Clarify that factories and stores rely on raw ingredients from the farm and natural world. Every picture or product should now be in either the “Farms” or “Natural Resources” container.
6. Explain to the students that farms need water, soil, the sun, and air to grow and raise plants and animals. To illustrate, place the "Farms" box inside the "Natural Resources" box.
