Quick Check - Reading a Graduated Cylinder

Just a quick check to see if you're ready to move on!  Look at the level of water in each graduated cylinder and write your answers on the scrap paper at your station.  You can easily enlarge the image in order to see it better.

Quick Check Graduated Cylinder

Look at the level of liquid in the graduated cylinder.  In the form below the picture, write your answer for each cylinder.

LET'S GET PRECISE!

In our recent labs we've continued to work on precision. From the 3cm ruler activity to the Rainbow Lab.... it's all about being precise.   But why?? Why is it so important to be precise?  Think about it!  So many reasons - in science... and in life actually.  Check out this video of Desean Jackson - he's talking about precision in football!  (Of course, I have no idea who Desean Jackson is... but Mr. Emerson shared this with me.  I guess he's some sort of famous wide receiver eh?)  PRECISION!  Skip to 2:05 to get to the precision part if you wish.



REFLECTION..... Create a blog post and do the following:
1) Label your post properly for science

2) Go to creative commons and find a picture of someone being really precise

3) Write a strong explanation of why precision is an important skill for science and life

4) Include an example from outside of school where being precise is important.  This can be from you or from an adult job or experience you or someone you know has had.

Observation and Inference Quick Check

Volume of Liquids

How would you find out the amount of coffee that is in this mug?  How would you measure it?

Today we'll learn how to accurately Read a Graduated Cylinder and work on a lab to find out just how accurate you are!

Rainbow Lab

Observation, Inference, and Precision in Measurement!

Today in class you went over your balloon observations - qualitative and quantitative.  Fun eh?  You also learned a new concept - Inference - making sense of the observations; an explanation of what that observation means.  For example, you saw bubbles as soon as you mixed the vinegar and baking soda. From that you would infer that a chemical reaction is happening and a gas is being produced.  Get it?  Start working on your observation/inference experiments this week at home.  They are due Friday for class C and E.  Monday for classes B,D,F. 

Practice precision in measuring by visiting the following website and working through it. You need to scroll toward the bottom of the site to reach the interactive measurement slides.  See how well you can do.   Click here for the Interactive Meausurement Website 

If you finish that, put in your ear buds and watch Bill Nye's clip on measurement

Observations

Today in class we finished up with the most common types of lab equipment and started talking about the importance of good observations and measurements in science.  If you weren't in class today, or if you'd like to share this video with your parents --- it's all about good observations!  Count the number of times the players in white pass the basketball. Cheerio!

Solutions

We've discussed global water problems, shared facts, looked at causes and now let's look at some of the things people and organizations are doing to help. Check out these websites - and any others you find on your own. When you find a piece of information you'd like to share, put it on the padlet wall below, as I showed in class. Hopefully this will work! If not, then just comment on the post and share your information. There are so many wonderful organizations and inventions out there!  Here are a few.....
ICT
The water project, 
Global Water Challenge,
The Other 90 Percent,
Water.org .

When you share your information on the wall below, PLEASE TRY NOT TO OVERLAP ENTRIES ONTO EACH OTHER.  You can move the wall around by dragging it and moving it right or down.  That way we'll have plenty of room for everyone.
Just move it until you find a good bit of blue, then double click and begin typing your information..Make sure you write the name of the organization or invention and also write a bit of information about it.   You can upload a picture or even video if you wish as well. Let's try to see if we can get everyone posting something different.
THAT will be just a bit too hard. One of my favorite inventions is The Hippo Roller -imagine how much easier it must be for these women than before.

Causes

Oxfam is an organization that dedicates itself to solving global issues.  Check out their slide show to find information about some of the causes of the water problems we face today.  Read about them - it's pretty basic, but gives you a general picture.  Write a blog post explaining a few of the causes - and of course include a picture to help your reader understand the post.

Causes of our Global Water Problems

Microlife in a Drop of Water

            Microlife in a drop of water!  (A video from under the microscope)

Yesterday we discovered that many of the infectious diseases we've been talking about in class are waterborne. For the next few days in class we'll be looking at some of the 'wretched beasties' that live in water.  

 For homework tonight, find three facts about our global water problems and waterborne infectious disease.  Post them to your blog - including a supporting picture.  Here are a few suggested sites - but you can research your own as well.   You might find better sites!

Microscopes - Part 2

Cell Theory, Germ theory - It's all going to come together soon!  In class,  after you get your LICENSE to operate the microscope, you'll be preparing and looking at plant cells from an onion skin, as well as animal cells from YOUR skin!  Here's a video to prep you for lab.  Click on How to Prepare a Slide.

Wow! Thanks, Catherine!!

AIDS patient cured!?  Catherine Edds shared this in class today.  You can read a full report from CNN here

Germ Theory of Disease

If you weren't in class today, be sure to watch the video (click on the picture) on the cell theory

This leads us to germs.  Some are cells, some are not - But - We do know that germs cause infectious disease.  It's a no brainer!

However, for hundreds of years people had no idea what caused infectious disease.  Many scientists and discoveries led to what is now known as The Germ Theory of Disease.   Your assignment is to read about the germ theory of disease and create something that shows your learning on this.  It's pretty straight forward.  We give you three options, and if you don't like those - then do your own!  This is due in two blocks so don't put it off!

Virtual Microscope

You're going a great job in class guiding your learning. For extra practice - do some virtual work using the same website as we used in our manual - virtual urchin. Click on the microscope icon to take you there. Peruse and work through the list of items on the left hand side of the site. It's kinda fun!  Scan the QR code for an extra little piece of information.

Microscope Practice

If you want to do some virtual work with the microscope - virtual urchin is a great site to use.  Click on the icon and peruse through the many options on the left of the site.

Cell Webquest

CELL.... WHAT'S A CELL?

*The cell is the smallest unit of all living things.
*They are the building blocks of LIFE.  
*IF IT'S EVER BEEN ALIVE - IT'S MADE OF CELLS!

**ALL LIVING THINGS ARE MADE OF CELLS**

In order to understand microbes (germs) we need to first understand cells and in order to understand cells we need to  quest - and in order to quest we need to click on the cell!
Homework:  Fill out the cell quest document.  You will have until next week to do this.  Make sure you "make a copy" if you are going to edit on the document.  Otherwise, just print it off and fill it in by hand.

Reading Writing Thinking Day

Video Clips

Coming up we'll be exploring the germ theory of disease.  I'm looking for short, informative video clips of the following scientists:  Hooke, Leeuwenhoek, Schleiden, Schwann, Siebold, Semmelweiss, Virchow, Nightingale, Pasteur, Lister, Koch, and Halsted. If you find one, please embedd it to your blog and then email the embedd code to me. Thanks!

Bubonic Plague

Typoid Mary was certainly the most famous carrier in the world, but what about the most famous vector?  Is there a most famous vector too?  The mosquitos which carry dengue and malaria are well known culprits, but in the late 1800s and early 1900s it was a little fellow that lived on the rat that came to stardom.  Watch this very short segment on the bubonic plague by clicking on the picture (adapted from Science Odyssee).

Clinical Trial 6A Data

Halloween Science

Side Effects

During our simulation of clinical trials we talked about side effects.  Check out the video of the side effects David experienced after his dental surgery.  Love it!

Clinical Trials

When trying to find a cure for Pellagra, Golberger performed what was to be referred to as a 'clinical trial'. Today clinical trials are used to test new medicines and procedures.  To further understand clinical trials, click on the image and follow the tutorial.
If you want some extra credit, then create a blog post explaining all about clinical trials. Be creative with your post.  Try to go beyond just using text.  Maybe use an xtranormal cartoon or something like that.  In addition to explaining a clinical trial, talk about protocol, placebos, and consent. Either on the form below - or in your journal - define each term.

Studying People Scientifically

From Saving Fred to All Aboard, approaching problems involves well thought out methods.

What if you're studying people instead of solving a problem like we did in class today?  Does the problem solving method change?  Do you need to think about what's ethical with human testing? What's right and wrong? Next class we will be looking into one doctor's attempt at solving a serious health problem which existed in the Southern United States in the 1900s.  Watch the video (click on Dr. Goldberger's picture) and think about these questions:
1.  What was the problem of pellagra?
2.  What did people think caused pellegra?
3.   What evidence did Dr. Goldberger observe or collect about pellegra?
4.  What did Dr. Goldberger conclude about the cause of pellegra?
5.  What are your thoughts about the right and the wrong in Dr. Goldberger's testing to solve this problem?

For more information on Dr. Goldberger and Pellegra - see  http://sepuplhs.org/students/sali/ 

Density of Liquids and Solids

We've completed a number of labs on density of solids and liquids. For more practice- pick from two optional pieces of homework. You don't have to do both to get the 'bucks'. Just pick one that suits your fancy.

Kitchen Layers- follow the guidelines on this sheet but instead of drawing a picture and explaining - make a blog post with a photo or video and include an explanation - immiscible, interface, density etc.

Gizmo - click on the interactive density picture in this post and it will take to you to gizmos. Log in and go to the density lab we played with in class. Fill out this sheet as
you manipulate the shapes and find their volume, mass, and density.

Water Displcement

Density

The next concept we'll touch on briefly is density.  As defined it is - The amount of mass per cubic volume and the unit we use is g/cm3 (that is supposed to be a superscript 3 but I don't know how to make it on this format!). Think about what g/cm3 might really mean. To help understand what density is, click on my picture and listen up.To help understand how to calculate the density of an object, watch Nathan's video .  You'll see a familiar face! (and I hope you know the song 'Popular'.)
 When you're finished listening to me and watching the video, please give a quick explanation below.  If the form doesn't show up at the bottom of this post then just write a brief understanding of density in your log book.  Hopefully the form works and you can submit it.

Holy Gumball Batman!

Today in class you brainstormed and explored ways to find out how much of a gum's mass is sugar.  After much discussion and setting standards to control variables you found the answer! Holy Gumball Batman, that's alot of sugar! Hope you have fun recording it all on your blog. Remember - if you have difficulties with the video, then just write about the experiment and include an image to help the reader understand.
(This post is for Monday's class only - Classes that have science on Tuesday aren't quite here yet)

Click on this picture to find out just how many sugar cubes are in your favorite foods.

Mass vs. Weight

Next science class, we'll be doing a lab called Looking for Mr. Mass.  Watch this video and sing along! Do you recognize the song? If you don't, I bet your parents will! Have good fun with it. He's a quirky, goofy, guy! Below the video is one question I'd like you to answer. Don't forget to scroll down. 

And by the way - I'll give a worm buck to anyone who comes into science class singing the chorus to the song!

Blogging Survey

This is your opportunity to share your feelings, thoughts, and ideas regarding our newly created blogs. I look forward to reading your responses! One great thing about blogging is that we will be constantly learning from each other and sharing our work.

Well Done!

In the last couple of days we put 'science' on the back burner and have been hot to trot with setting up our blogs.  You now all have a blog and have included many features and links that will come in quite handy in the future.  You should have the following on your blog:

• One homework calendar for all subjects - some with daily agenda as well.
• All Gamma A teacher blog links
• Gamma A website link
• One post with labels all set and ready to go.

If you got lost and dazed along the way - please don't stress!  Just come to me and we'll set up a time to redo everything  together.  It is such a cool tool to use - I don't want anyone feeling overwhelmed. Please just come and see me - or try to use the instruction links at the end of this post to reset anything you need to.
Make sure you finish your welcome blog post before next class. I look forward to sharing and commenting with you!  Happy Blogging!

Great job everyone!  Can't wait to see what you all do with your earnings.

Water Chemistry!

Chemistry!
As we segue into our study of chemistry, think about all of the connections chemistry has with water -  from the water molecule itself, to the chemicals used for water sanitation.
A few years ago, shortly after the Haiti disaster, I was watching Larry King Live.  I was astonished at this little packet of chemicals called PUR and the tremendous change it could make in the lives of thousands.  Take a look.

Happy World Water Day! March 22

What an Opportunity!

Thanks to  Hana M., I enjoyed a private tour of world class bioimaging and the chance to operate an electron microscope. Absolutely thrilling!  We looked at three electron microscopes, including the Titan Krios - a five million dollar microscope of which there are only fifteen in the world.  What an experience!  Imagine if you could actually view the microbe you're studying right now.  Imagine.

An image of a virus discovered in Yellowston
This was viewed with the Titan Krios

Humorous Microbes!

Gary Larson is one of my favorite cartoonists - the creator of the Far Side - a very famous single panel cartoon series.  Satirical, humorous - and always a play on words.  Check out this one that plays on the structure of amoebas.  Do you get it?
Perhaps you're the next Gary Larson.  For extra credit, create a cartoon of a microbe - any kind of microbe - bacteria, protist, virus - anything.  Just make sure the cartoon shows your understanding of both the structure and the function of the microbe.  Have fun and good luck!  Bring it in any time within the next couple of weeks.

Dengue, Anyone?

 A number of days ago, during our investigation of microscopic organisms, I walked into the lab and was overwhelmed with the stench of decay.  Beakers full of dead tubifex worms.  Oooh, nasty!  We disposed of them in a pitcher outside and then pretty much forgot about it. When I finally remembered (many days and rainfalls later) I found it crawling with new life forms! Hundreds of them - all in various stages of development.  Fascinating.  They are now nicely evolving under controlled conditions in the lab.  Let's see what happens.
Here's a short clip on the life cycle of a mosquito
