Tasha is running around the yard with her friends on a hot summer day. After about an hour, she's flushed and sweaty. Tasha's mom calls her in to cool off and rehydrate. She hands Tasha a glass of ice water. Tasha asks her mom how water becomes ice. Describe the process of how water freezes. Use information from this week's lesson to support your answer. (Hint: Consider the polarity of water and hydrogen bonding.) Knowing that the human body is approximately 60% water, and that some organisms live in water, what is the importance of temperature regulation? Scientists use the presence of water as a measure of the possibility of life on a planet. Knowing that the surface temperature on Mars averages -67 degrees Fahrenheit, do you believe that the properties of water (discussed here and in your text) would support life? Why or why not?
