The daily questions for Tuesday went RIGHT along with Monday's discussion about heat of vaporization:
Of all the properties of water that help support life, waters specific heat/heat of vaporization and heat of fusion are probably the one we can relate to the most. We moved into the density of water and water a "universal" solvent:
I showed you guys this video that details the different densities of water:
Finally, we finished up the last property important to life.
On Thursday we took our Daily Question quiz due to the shortened periods on Friday. After the daily question quiz we went through the notes on specific heat. Friday I had you log in to Tyler SIS to make sure you know how to log in and see your grades. We will do that again tomorrow. Today we continued through specific heat. Here are today's daily questions and the notes from Thursday AND today.
I didn't get a chance to do a screen cast of today's daily question. This last question is VERY important to understand. If you were absent today I encourage you to watch the following Khan Academy video that discusses what i was drawing.
Here were notes from Thursday and today. I have included some videos that I used in some classes. Again, I encourage you to watch some of these if you were seeing as though this is a tough concept to digest!
We have been looking at the properties of water that are important for life. Yesterday we focussed on cohesion and how it causes surface tension. Here is another look at cohesion and surface tension.
Today we looked at Adhesion and capillary action. Here were today's Daily Questions:
I used the following image to show you the differences in density among solid, liquid and gas water.
Here is a little video of my discussion about some adhesion that we saw YESTERDAY in class:
Then into the notes and activities:
And we took a look at adhesion and cohesion/surface tension by adding water onto pennies
For a dramatic look at what happened - Check out this youtube clip:
We used capillary tubes to show capillary action:
This is important in moving water up the roots of plants - Here is a neat time lapse video showing how capillary action brings a plant "back to life"
Today we brought together our knowledge of Basic Chemistry to the properties of water. Here were the daily questions:
We then went into some notes / drawings / activities to understand the chemistry of Water ***NOTE: I encourage you to watch the following Khan Academy Video if you missed today's discussion / demonstrations:
Then we used our "cups of water" to build 5 water molecules
Reminder: DAILY QUESTION QUIZ TOMORROW!!!! (Intro to water and basic chemistry) Yesterday we had a daily question extravaganza about the properties of water. While water is CRUCIAL to life and have many "life giving" properties, we need to have a basic understanding of atoms to start. Today's daily questions were to see what, if anything, you remember about the parts of an atom. I was encouraged to see that while you may have not remembered it ALL, many of you could talk through some of the parts:
Then on to our first set of notes for this section:
