1. 1.

   What does compressibility measure?

   Hint

   Think about how a sponge behaves.

2. 2.

   What does a higher Swelling Index indicate?

   Hint

   Is more swelling better or worse?

3. 3.

   What does the Swelling Index measure?

   • Change in pressure
   • Change in moisture
   • Volume change with moisture

   Hint

   Think about how plants absorb water.

4. 4.

   Compressibility refers to the ability of a material to decrease in volume under pressure. True or False?

   • True
   • False

   Hint

   Consider what happens to a sponge.

5. 5.

   Consider a building site where the soil has a high Swelling Index. What design strategies could engineers implement to mitigate potential problems?

   Hint

   Think about what you would do to secure a wobbly table.

6. 6.

   A civil engineer determines that a nearby river impacts the soil's moisture levels significantly. Propose a study to examine the effects on compressibility properties.

   Hint

   What would you need to track?
