Watery Earth Lesson 2.3 - How Frogs Use Water

I'm sure you know that frogs need water to survive, but do you know all the different ways they need water? Well, of course they need water to drink because if they didn't get enough they would die of dehydration. But there are other ways frog need water too, like the reason they live in/by the water. If they didn't, their slimy skin would dry out, and they would die. If they ever are without water for a long period of time, their skin would dry out. For this reason, all frogs really depend on water for survival, in a way unlike other animals. Some frogs hibernate under water when winter comes, but not all frogs hibernate this way.

Humans

• Humans don't need to keep our skin wet
• Humans need water to wash themselves
• Humans use water to clean other things
  

Frogs

• Frogs need water to keep their skin wet
• Frogs don't need to wash themselves, they already spend most of their time in the water
• Frogs don't need to clean other things because they don't need to
  

Both

• Both need to drink water to survive
• Both like to swim in water
• Both play in water
  

1.   Why is water considered a "Natural Resource?"
 2.   How is water essential (required) to our survival and the survival of all living things?

1. Water is considered a natural resource because it can only come from nature and can not be made by humans.
2. Water is required for survival of all living things because we all need to drink it, and if we go over our limit of time without drinking it, we will die of dehydration.
