Pressurized Gas

We explore what happens when you shake a can of soda in this episode of Science With Hannah. 

True or False?  Tapping on the top of the can will keep your soda from exploding after it has been shaken.  The answer:  False, tapping on the sides and the bottom work, but tapping on the top does not because the bubbles on the top are not responsible for the explosion...but the ones stuck to the sides and bottom are..

Chemical Change

The activity is like magic!  But, it's really just a chemical reaction that changes the color of a nail. 


Gas- air is a gas


This activity is so simple.   But the results are surprising to most people!  I bet you have everything you need to do this in your kitchen.  Have fun!




Polar and non-polar molecules- SWIRLY MILK!

The activity in this video is so much fun and even a little artistic!  Molecules can be repelled and attracted to one another based on many characteristics.  In this activity, you'll see how milk swirls around by adding a little bit of soap to it.




Another thing to think about when watching, is how soap removes the oil and other gunk from your body when you take a bath!  One end of the soap attracts the oil while the other attracts water.  The soap and water get washed away leaving you with clean hair and skin!
