Set Up:
1. Print out a variety of pictures of everyday objects. Also, have some blank sheets so students can make up their own objects. Tie a string to them so they can be worn as nametags (op onal).
2. Print a picture of soil and set it in the middle of the room or in the middle of the wall.
3. Print out pictures of intermediate products.
4. Cut lengths of ribbon or string (4‐5 feet, one for each student) and affix one end to the picture of the soil.
Notes:
The web can be built on the wall (requires tape) or in the middle of the floor.
Prin ng on cardstock or lamina ng lets you reuse the pictures for mul ple groups.
If you have a small space, print out pictures on notecards rather than full sheets.
Introduce the Ac vity Ask: Have you thought about the soil today? Did you know that you’ve already relied on the soil in many ways this morning, without even knowing it?
The Soil Web
Step 1: A soil chain. Hand out the pictures of objects. You could pass them out randomly, or ask students to name an item they used this morning, and hand them the corresponding picture. Ask your students to think about how that object is derived from soil and to draw a chain represen ng this rela onship. Provide an example if they need inspira on:
T‐shirt —> Fibers/Tex les —> Crops (co on) —> Soil
Some objects may have more than one link to the soil. For example, furniture requires both lumber and fiber. If the students iden fy both, great. If not, that’s OK; they can just focus on one linkage. Have students work in small groups to share their chains with each other and discuss.
Step 2: Create the soil web. Have students a ach one end of the yarn to the soil picture and hold the other with their object. Have them iden fy intermediates in their soil chain and clip them to the yarn. Note that mul ple objects will share the same intermediate steps, so students will have to work together to build this web.
Varia on: Print mini versions of the objects, a ach to magnets, and arrange on a magne c black/white board. Draw the links between the objects.
Generalize and Apply Ask your students to take the perspec ve of various professions, and think about why soil is important from their perspec ve.

In this ac vity, students will build a web that connects everyday objects to the soil,
learning that soils support many important products and services.

The Soil Web
Notes: – “Soil” goes in the center of the web
– Items with green dots are everyday objects and will be the outermost part of the web – pass these out to your students. Everyday objects may have more than one link back to soil.
– Items with blue dots are intermediate products or services that soils provide. These will be the inner links between soils and the everyday objects. Multiple objects may link through the same intermediate.
