Air Pressure Giveaway and Blog Hop!

Today, I want to take a closer look at air pressure!

Below, you'll find several amazing air pressure demonstrations (and some explanations)  - many of which you can repeat in your classroom!

You'll also find a related product from my TpT store - the Air Pressure Lab Pack. This product includes four experiments students can complete - and one comment on this post will win it FREE! (Comments/giveaway close at the end of the day on Sunday, 12/16/12).
Be sure to stop by on Monday to see if you've won!

Also, we're running a blog hop! Check out the links at the bottom of the post to follow the hop!

Enjoy!

Air Pressure is STRONG!

Wish you could do this in your classroom?

Well, you can! (Sort of).

See the next video!

The Amazing Smooshing Can!

I usually use this demo to introduce air pressure.
As students learn, they are able to explain what happens!



Another great air pressure demo for the classroom!

Low air pressure created by the burning oxygen leaves relatively high pressure outside.
This high pressure pushes the liquid into the cup!



Some engaging labs for students from my TpT store!

One lucky commentor on this post will receive a FREE copy of this lab pack!
Be sure to stop by on Monday to see if you've won,
leave your email in your post,
or send it to me at ScienceTeacherResources@ymail.com.
I promise no spam - I'll just need to contact you if you win!

Another great demo!
(and some more detail on how air pressure works)

More Awesome Science! (videos and resources)

Time for some more awesome science -

With some student friendly, ready to use teaching materials to match!

Time Lapse Erosion

Two amazing looks at erosion - aided by time lapse! Above,

Collaroy-Narrabeen Beach (Sydney, Australia) in June 2007. During 3 days,

almost 300 000 cubic meters of sand was removed from the beach.

Below, the erosion of a soccer ball over time.

Both work well with one of my freebie resources:

FREE Rock Cycle Simulation Lab 

 

The Egg in the Bottle

Whoa! The fire consumes the oxygen - around 21% of the air inside the bottle.

This leaves relatively low pressure inside the bottle (as compared to

the relatively high pressure outside the bottle). This higher pressure outside

air pushes the egg in!

This demo is a great match with

my Air Pressure Lab Pack or Percent Oxygen Lab!

The Ultimate Zoom-In Shot

 One of my (and student) favorites! 
A simulated zoom from the outskirts of the universe to the inside of an atom!
This is great for looking at relative sizes, and can easily be paired with my  
Cells vs. Atoms Worksheet.




The Blubber Glove

I have a friend who participated in a pain study at the National Institutes of Health.

She had to keep her hand in ice water as long as she could stand it - too bad

she didn't have blubber! Blubber is an incredible insulator, allowing very little heat to

transfer from the hand to the water!

This demo makes for some great lessons when paired with my Conduction Lab, 

Heat Notes Pages, Heat Transfer Practice Worksheet,and FREE Heat MiniQuiz.

Or get them all (and more) with the Heat Transfer Teacher Pack!

Correct Horse Battery Staple (awesome science websites)

My brother showed this one to me. Awesome.

It's from

 xkcd.com 

A very cool (and addictive) math/science web-comic.

I especially like the What If section, self described as "Answering Your Hypothetical Questions With Physics, Every Tuesday." 
Disclaimer: I've browsed the site, but can't vouch for 100% kid-friendliness.

Planet-Science.com

Cool and amazing videos, experiments, and a special section for parents and teachers!

HowStuffWorks.com

Ok, so you may have heard of this one, but I had to include it.

It's too awesome not to.Wonder how anything (real or imagined) works?

You can probably find out here.

Gross! (and Awesome) Lab

One of the messiest, grossest, and BEST labs that I have - Oobleck!

With very simple materials, students can create this strangely behaving non-Newtonian fluid. It acts like a liquid when handled slowly, but solidifies when handled quickly! (I usually use it in my middle school classroom to teach about atomic/molecular motion in solids and liquids).

A day or two day ago, I uploaded the lab to my Teachers Pay Teachers store.
(See it here - there's a free downloadable preview).

Due to some curriculum and grade level changes, I haven't had the opportunity to do this lab with my classes in a couple of years, but looking it over reminded me what a great learning experience it is - I've had kids come back to me years later and still remember it.

Below are some videos (not of me or my class) showing Oobleck's strange behavior. 
Think you know how it works? The first three comments on this post get the lab and key for free! (Please leave your email address in the comment, or email it to me separately if you'd prefer).

There's also a recipe that involves glue and Borax.

 I haven't used it, but I know others who have:
