Want to know about the properties of water just check out some of the resources we found!!!
Overview
Evan offers this video clip
Nancy found a fantastic wayto understand why and how the water molecule is called a polar molecule. She explains that “H20 has two poles. Hydrogen is slightly positive and the oxygen pole is slightly negative. When two water molecules combine it creates a weak hydrogen bond.” Or this one.
Water is a polar molecule. AnnaD found a terrific animation that shows how the hydrogen bonds form. Erica found this video on bonds…what do you think?
Water covers 70% of the earth’s surface and has unique properties
Katharina found this video that explains
Physical properties of water by Science Steve is something EmmaV found
Bella thought this animation and stop-action movie was very helpful but uses some big words so be ready. You could make a movie like this!!!!
Romila found a 3D representationof the water molecule.. She explains “ My video explained the water molecule. It shows you how molecules are attracted to each other and bond. It also explains how and why water is known as H2O(there are 2 hydrogen atoms and 1 oxygen atom in a water molecule).”
Capillary Action
Natalie says it is on capillary action and it helped me understand what capillary action was and it gave me an example of it. It is an experiment and it uses two glasses (one filled with water, one empty) and a paper towel.
Gerry found this video on both Capillary Action and Surface Tension. Short but very helpful in illustrating the properties.
Sarah says, “This video us about capillary action, and how two hydrophilic particles attract each other. They also push away from each other. This is pretty cool to watch!
Colored water travels upwards, defying gravity and show capillary action. Sent in by Emily.
Surface Tension
Watch how surface tension works in this video that EmmaV found
Emerson and Claire made this Blabberize about how cohesion and adhesion works
AlexP found a crazy and “strange” video that shows surface tension at work or this demo of the attraction power of water. He also found a science segment from a news show that explains how paperclips can float on water.
Adian offered this robot that walks on water using surface tension.
“This video”, says Conor, “shows an experiment done at Berkley which displays surface tension. They drop aluminum coins into a tub of water. They should sink, but they stay afloat because of surface tension! They then break the surface tension by adding soap to the water. The aluminum coins immediately sink to the bottom of the tub. Fascinating! ”
Universal Solvent
EmmaV and Greta found an amazing animation of how water dissolves salt…(plus you can work on learning French by reading the subtitles)
Nathan found a terrific video that shows how water works to dissolve salt.
EmilyA found this teacher’s explanation how water is a univeral solvent and uses models of the water molecule to demonstrate exactly how those slightly charged areas of the molecule work. 2nd Hour thought it was a little up too close, but the information is wonderful.
Specific Heat
What do you think of this Storytime video which explains specific heat that EmmaV found?
Other Properties of Water
Watch water freeze before your eyes with this animation that Greta found.
Tianna sent this video on the understanding atoms,elements and molecules.
Chloe found a wonderful lab that you can do at home. It looks at the density of water. She says “This video shows what happens when you put water that is less dense on water that is more dense and vice versa. Do they mix?”
“This is a new animation I found that shows water molecules in all 3 states of matter (liquid, solid, gas.) “, says Clark.
