The Hydrosphere!

This week it was our turn to share on Science Monday!  Our focus for this week was the HYDROSPHERE!

We learned that 75% of the Earth is covered in water!  Next we had to guess how much of the water on Earth is salt water and how much is fresh water.  Using a small piece of paper to represent all of the water on the planet, we colored in how much of the water we thought was salt water. 

Then we shared our guesses with the rest of the TLC.  How much of the water on Earth do you think is salt water? 

It turns out, 97% of the water on Earth is salt water!  Of the 3% of water that is fresh, 2% is frozen!  That means just 1% of all the water on Earth is available fresh water! 

Next we learned about the Water Cycle.  Two Islesford students presented a slide show about the Water Cycle and then we watched an animation to further explain the process.  Next we modeled the Water Cycle with our bodies.  Here the whole TLC is condensing! 

Next, each school had to come up with a series of tableaux to demonstrate the Water Cycle.  Can you imagine these kiddos evaporating? 


Running off and collecting!  Every school took turns presenting their tableaux to the other TLC schools.  We finished the lesson with a discussion about the Water Cycle, how we use fresh water and questions we have about water on Earth.

Everyone enjoyed learning about the Water Cycle!
