Properties of water wrap up

We finished up the properties of water that help support life today - starting with the following daily questions:

Notes for today

How about staying in an ice hotel?!?!?!

Properties of water demonstrations day 2

GREAT start to the properties of water demonstrations!!!  We started with the following daily question before heading into our next set of activities.

We moved into our next look at Cohesion by adding pennies to a full jar of water to see how many we could add before if overflowed.  Some of you were able to get MANY pennies in there.  Why did this happen??????  Even though the jar was full, the water is SOOO attracted to other water molecules the Hydrogen bonds just get stronger and stronger and the water at the surface keeps "pulling" itself down to keep those bonds.

Next up was Adhesion and Capillary action.
Here were the notes:

And our next activity was using a capillary tube to watch water "climb" up!!

Here is a good video that discusses some of these properties of water we have looked at so far and are going to be looking at tomorrow.

Properties of water notes and demonstrations day 1

Announcements / Reminders

WEDNESDAY we will have a Water Lab Wrap up.

FRIDAY we will have our normal daily question quiz.

When you guys came in today you noticed that your desks had set ups something like this:

I started you off with the following daily questions and discussions.

We reviewed the concept of hydrogen bonding between water molecules using the models we worked with on Friday.

Next up was to see what the chemical properties of water have to do with life.  To give you a little "teaser" on this we watched the following introduction video.

Then into the first property of water:

And then our first demonstrations:

You poured water from your beaker into the baby food jar until it reached the rim and SLIGHTLY higher.  This showed you immediately the power of surface tension.



You then used pins to see how they can float.  This was to simulate what happens with many insects on water.

Some of you had a chance to watch this short video that shows how surface tension works.

Finish up Bonding - Introduction to water

Reminder:  DAILY QUESTION QUIZ TOMORROW!!!!!

Today's daily questions:

We ran through a little more about bonds and how molecules are held together:

I then gave you BACK your pre-assessment and you were to complete it again for credit.

As an introduction to water I had you watch the following crash course.  I use these a lot throughout the year either to introduce a topic or do a quick review.  Hank Green is kind of like the male version of me... so it should not surprise you at how fast he talks!!

Ions and Bonding

We started with some in depth daily questions today:  There are some images of the answers but i highly recommend watching  the screen cast if you were out so you fully understand how we got to the answers we did.

Then Into Notes for today:

 

Chemistry of life intro..... Lets see what you remember!!!!!

Today's daily questions were a good way for me to see what you remember from physical science.  I was VERY please with how much you remembered!!  This will help us FLY through the first part of the chapter!!!

Next up you did a little pre-assessment on this first section - this is NOT going to be graded - just a way for me to accurately see what you understand and what areas you may still be a little foggy on.

Since everything in my world is a production of sorts - I had another "movie trailer" to spark you interest a little in this 

Then we started into some notes!!

I had some visual images of the nucleus and electron clouds with 

Here is the nucleus.  Not the most exciting place to be.  It houses the protons and neutrons.  Sooooooo  it may be a POSITIVE place to be..... Not much action happening here.

Now we move to party central of the atom, the electron cloud.  The electrons NEVER stop moving and are always looking to make friends with other atoms.  THIS is the place we are going to be focusing our attention the most :)

Overall view of an atom!! (yes i stood on the desk to take this pic)

First Daily Question Quiz

Today was a relatively relaxed day for you guys.  You got your school pictures taken.... which is always a blast....

Then I gave you some time to finish up the lab questions from the activities we did over the past two days.

Finally we took our first Daily Question Quiz!!   That was it for this first unit. 

This was just a quick way to show you in general what it means to be alive... other than....

Next week we will get into our first in depth unit - Chemistry of life.

Happy Labor Day - Enjoy your long weekend!!!
