I Scream, You Scream
From Step 2007 Wiki
Our group incorporated global climate change by developing a lesson about matter changing from one form to another. Our lesson is about changing liquid matter to solid matter and classifying matter according to physical properties. These concepts are linked to climate change when we study about how sea ice, ice shelves, and glaciers are melting due to the higher average Earth temperatures.
A liquid will change its form. Salt will change the freezing point of water. Good scientists take careful measurements. What will happen to this liquid? Changing matter is delicious.
