AGHS - Bio - Water Properties Virtual Lab - Casey Rurode | Library

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.

1

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!

1

What must be true about human skin if water can stick to it?

Video #2 - Answer the next question about this video.

1

Identify the property of water is BEST shown in this video clip. Which property allowed the water droplet to behave in this way?

Video #3 - Answer the next few questions about this video.

1

Identify the property of water is BEST shown in this video clip when the items "merge".

1

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?

1

Ultimately, why do molecules of water have the ability to attract one another or stick together?

Video #4 - Answer the next few questions about this video.

1

Identify the property of water is BEST shown in this video clip.

1

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!

Video #5 - Answer the next few questions about this video.

1

Identify the property of water is BEST shown in this video clip of sugar dissolving.

1

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.

Video #6 - Answer the next few questions about this video.

1

What must be true about the molecules oil given the events of this video?

1

What do you know when you look at the final location of the oil at the end of the 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!

1

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!

1

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

1

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!
