Wednesday September 30th - Adhesion and Capillary Action

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"

Tuesday September 29th - Wonders of Water Day 2 - Cohesion and Surface Tension

Today we started into the properties of water and how they support life. Today you started with the following warm up.

Screencast of the discussion around this:

We then watched the following "Movie Trailer" for this section.

This was the only slide of notes we took - the rest of the period was SEEING this property of water in action.

Filling up our jars with water

Dropping pennies in to see how many we could add until the water spilled over.

Taking a look at surface tension by balancing pins on the water.

It was a MESSY day in room 220 that's for sure!!

SOME classes got a chance to see the following two clips that show in slow motion the concept of surface tension:

The second video can be found at

Monday September 28th - Properties of Water Day 1

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

 And then you diagramed that on your desks!!

Friday September 25th - Basic Chem and Water Intro DQQ - Finish up basic chem notes

BEFORE the daily question quiz I had you watch the following crash course as a nice review / introduction to the properties of water.

We then took our daily question quiz.

AFTER that we did finish up notes on the different types of bonds:

Thursday September 24th - Basics of Chemistry

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:

Wednesday September 23rd - Daily Question Extravaganza!!!!

     Today we spent the entire period going through a variety of Daily Questions that introduce us to the wonders of water.
     You used the KEYSTONE Finish Line books (Book pages available here) to search for answers to both yesterday and today's daily questions.
     Here are some screen shots of the questions and then a screencast of our discussion follows.

The answer to that last one is A (Cohesion allows droplets to form, and adhesion keeps the droplets on the needles)

Tuesday September 22nd - Chemistry of Life Pre-Test

FIRST on your agenda today - go to Study Island - Login -- Go to "my classes" - Click on Biology 2015-2016

There is an assessment called "Chemistry of Life Pre-Test" - Take this.

Once you have finished the pre-test -  grab  a KEYSTONE Finish Line book

 - you will use pages 26-28 to answer the following Daily Questions (Please put these in your notebook - you can start a new section of Daily Questions)

Monday September 21st - First Round of CDTs

Happy Monday All!!!!

Today we took our first CDT

This test is to show your progress throughout the school year.   It assesses how well you are doing on each section of the Keystone Exam content.  I expected pretty low scores since well....... we haven't learned it yet!!!

I WAS impressed though with your baseline scores.  This shows me you guys came in with a pretty solid background.  That is encouraging for sure!!

Those of you who did not finish today will finish that up tomorrow and we will all take a Study Island pre-test for the next unit - Chemistry of Life.

Friday September 18th - Daily Question Quiz!!!
