This assignment will provide you with opportunities to apply water properties to different video clips. These don't show you why the properties are essential for life but they clearly demonstrate one of those characteristics that allow life to exist on Earth.
Part 1 - Identifying the Observed Properties

In this section, each option for identifying the chracteristics of water will be used only one time so select the property that is BEST shown. TWO properties of water will not be used in this section.
Video #1 - Answer the next few questions about this video.

Part 2 - Understanding How These Properties are Helpful for Living Organisms

In this section, you will explain how the requested property of water is helpful for life
EXAMPLE: This video deomonstrates why cohesion and adhesion are helpful to life. Without these properties happening inside of plants to move water from the roots to the leaves, the plants would die and consumers would not have a source of food. This also explain how plants lose water/sweat like what was discussed at the end of the EdPuzzle!
Question 13
13.

Explain why water expanding as it freezes is helpful for life. There is more than one correct answer here!

No credit will be awarded with you do not clearly state how living organisms benefit form this property!

Question 14
14.

High specific heat is another property of water. This means that it takes a lot of energy for the temperature of water to change. Explain why this property is important for life. There is more than one correct answer here!

No credit will be awarded with you do not clearly state how living organisms benefit form this property!

Part 3 - Understanding How The Properties of Water can do Harm - A Human Impact Story
In this section, you will explain how the requested property of water is helpful for life
Question 15
15.

In this video we see the danger of water being a universal solvent.

A) Explain how water's ability to dissolve substances can be harmful when humans do everyday activities like throw away a plastic bottle (1 pt). Spiral this out and explain how one small act can have a larger an unexpected impact on living organsisms or the biosphere as a whole. (1 pt)

***This isn't meant to make you feel bad, but rather make you aware of the consequences of our daily activities!

Identify the property of water is BEST shown in this video clip. The astronaut draws attention to it at the very end of the clip!
evaporation
high specific heat of water
ice expanding
adhesion
surface tension
solvent
cohesion
What must be true about human skin if water can stick to it?
skin is nonpolar; it does not have charges
skin is polar; it does not have charges
skin is nonpolar; it has charges
skin is polar; it has charges
Identify the property of water is BEST shown in this video clip. Which property allowed the water droplet to behave in this way?
cohesion
evaporation
ice expanding
solvent
high specific heat of water
surface tension
adhesion
Identify the property of water is BEST shown in this video clip when the items "merge".
adhesion
cohesion
evaporation
high specific heat of water
ice expanding
solvent
surface tension
In the merging droplets video, the astronaut says that our observations are due to the "attracticve forces" between the very large droplets of water (FYI- each droplet is made up of trillions, or maybe even more, molecules of water). What scientific term describes this attraction between water molecules?
nonpolar covalent bond
hydrogen bond
polar covalent bond
ionic bond
Ultimately, why do molecules of water have the ability to attract one another or stick together?
In the ionic bonds between oxygen and the hydrogens of one molecule, there is an unequal sharing of electrons
In the covalent bonds between oxygen and the hydrogens of one molecule, there is an unequal sharing of electrons
In the hydrogen bonds between oxygen and the hydrogens of one molecule, there is an unequal sharing of electrons
Identify the property of water is BEST shown in this video clip.
adhesion
solvent
evaporation
ice expanding
cohesion
high specific heat of water
surface tension
Dive deeper, which substance can absorb more heat or energy from a surface and why? Keep in mind, both liquids were tested in identical environments!
rubbing alcohol; it could absorb energy for 1 minute and 15 seconds
water; it could absorb energy for 1 minute and 15 seconds
water; it could absorb energy for 45 seconds
rubbing alcohol; it could absorb energy for 45 seconds
Identify the property of water is BEST shown in this video clip of sugar dissolving.
ice expanding
adhesion
surface tension
solvent
cohesion
evaporation
high specific heat of water
What must be true about the molecules of sugar given the events of this video? Recall, on a molecular level, that the water was attracted to the sugar molecules and separated the sugar.
sugar is polar
sugar is nonpolar
sugar is unique
What must be true about the molecules oil given the events of this video?
oil is polar
oil is nonpolar
oil is unique
What do you know when you look at the final location of the oil at the end of the video
oil more dense than water
oil and water have the same density
oil less dense than water
