What are loud? 

A humongous hippo roaring in the Amazon waters.

What are silent?

 Air on a warm spring morning.

What are hard?

Sticky cement on the solid ground.

What are soft?

Cotton clouds floating through the air.

What are heavy?

A beautiful bottle in a school backpack.

What are light?

Dandy clock seeds flying freely through the air.

What are cruel?

People toppeling trees for palm oil.

What are kind?

Terrific teacher telling a story.
