Water Systems

What are the big ideas from this Science Unit?

• Water is crucial to life on Earth.

• Water is not a concern for us, because Lake Ontario is huge.

• Water is an important resource that needs to be managed sustainably.

• Water systems influence climate and weather patterns.

sustainability

• being able to meet the needs of the present without compromising the ability of future generations to meet their own needs

• a note that is held for a duration of time

• recycling, as though "facilities exist" when in reality most of the things we recycle end up in the garbage because recycling facilities are sparse. We do not hold companies responsible for their packaging

• caring only about my needs and vowing to take action when the lack of finite resources begins to effect me

Floc

• loose clumps formed from the reaction of aluminium in water, combined with rocks and other waste liquids

• another word for alum

• sticky clumps formed from the reaction of alum in water, combined with sand and other waste solids

• waste solids

Water treatment

• treating water fairly

• a process used in spas in which water is used to plump the skin

• the process of removing potentially dangerous substances from water to make it more acceptable for a desired end-use

• the process of adding potentially dangerous substances to water to make it less acceptable for a desired end-use

Glacier

• a large piece of ice

• a river of ice, formed from snow accumulated over hundreds of years, that moves slowly downhill under the force of gravity

• the French word for ice cream

• a made up term that "Scientists" use when talking about their Global Warming conspiracies

Icecap

• a large area of ice that permanently covers land

• a river of ice, formed from snow accumulated over hundreds of years, that moves slowly downhill under the force of gravity

• a drink from Tim Hortons

• the top of a mountain

Polar ice sheet

• a frozen field of ice covering the equator

• a cookie sheet made for Polar Bear cookies

• another word for window

• a frozen field of ice covering either the North Pole or the South Pole

Precipitation

• leaving your work to the last minute

• solid or liquid water that floats into space

• solid or liquid water that stays in the atmosphere as clouds

• solid or liquid water that falls to Earth’s surface

Water table

• the depth at which loose rock and soil below Earth’s surface are saturated with oil; the upper boundary of an aquifer

• the depth at which sand under the Earth’s surface is saturated with water; the upper boundary of an aquifer

• the depth at which loose rock and soil below Earth’s surface are saturated with water; the upper boundary of an aquifer

• the depth at which loose rock and soil within a mountain are saturated with water; the upper boundary of an aquifer

Aquifer

• a geological formation of water

• a geological formation of loose rock or soil that is saturated with groundwater

• a geological formation of fur from prehistoric creatures

• a geological formation of solid rock through which water cannot flow
