Under Federal regulations, antifreeze is not a listed hazardous waste, but careless treatment of the product (i.e. disposal in storm sewers, septic systems, water ways, or even on the ground), can often result in hazardous conditions and effects. The good thing is, antifreeze can (and should!) be recycled.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProject Overview\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEmily predicted that it would be this recycled antifreeze that would be the least harmful to the environment.

As we exert ourselves, our bodies produce sweat (a liquid) which evaporates when it meets the air, taking some of our body's excess heat with it. The flip side of this phenomenon is that, if we don't replenish our body's store of water and continue to exercise, we can become dehydrated. (Be sure to read the full article on sweat at Kids Health!)
