5 fantastic science demonstrations to get your students excited!


It's Friday! I'm linking up once again with Doodle Bugs Teaching for her awesome Five for Friday weekly linky party.  This week, I've decided to spice up your classroom with some amazing science demonstrations that I'm sure will get your students sitting on the edge of their seats!

Sit back, enjoy while sipping your coffee and don't forget to visit Doodle Bugs Teaching for more great Five for Friday link ups!


Air & Gas Properties

Here is an amazing demonstration to show that CO2 gas is actually heavier than air!  I love it, because it shows you that the CO2 molecules are there, even though you can't see them.  The list of materials is short and easy, so get ready to amaze your students!





Gas, Liquid and Solids

Have you ever wondered why Ivory soap floats?  Me neither. In fact, I didn't know that it was the only soap that floated until I started doing some research for this blog post, but once I found this video, I knew I had to share!  I was amazed!  It even explains why it happens (which is perfect)





Light Bending

I always have a hard time teaching optics because I never have the proper material on hand!  But this video is really neat and shows how the light rays bend when they enter a difference substance and really does a good job of explaining why it happens.




And then I saw this video!  Now this you can do in your classroom with materials you probably already have!







Forces

I am absolutely LOVING this next demonstration! It's the perfect way to show how different forces work.  In the first example, the penny was only slowed down due to gravity (very little friction since it's round) and the hex nut slowed down much much faster due to friction AND created vibrations/sound waves! 






Heat

This is a classic, but this one has a twist!  It shows you how to get the egg back out of the bottle too!  It's easy to do, and I'm sure your students will love trying to figure out how it happens!





Any of these videos would also be great to do in front of your students and then let them figure out how it works!  Science is way too interesting not to have fun with it!

See you next week!
