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!

Cool Science Tricks

Today, I wanted to share some of the cool science that my class has been doing. 
(Although these particular videos aren't from my classroom, they showcase the science).
Enjoy!



Egg in Vinegar
When the egg is dissolved in vinegar, the shell dissolves, but leaves the inner membrane in tact. Besides being cool in general, it's a great example of diffusion - Certain fluids (and small solids) can pass through the membrane.

"Blowing Out" a Candle
When baking soda and vinegar are mixed, they create and invisible gas - carbon dioxide gas (the same stuff you breathe out). This gas is denser than air, and can be poured just like water. 

Decomposition of Water
Electric current breaks water into hydrogen and oxygen gas! The salt is to help the mixture conduct electricity. (A lab similar to this is available in my Teachers Pay Teachers store). 

 

Please share any cool or interesting science from your class!
