Many new words to process...

Our weekly visit from Science Mom really makes us think! We have many new science words to think about: solution, dissolve, catalyst, vacuum and pressure to name a few. 
By dropping sugar cubes into bottles of a solution (water), we watched them dissolve at varying rates depending on the temperature (catalyst) of the water.
How did she get that egg into the bottle?? As the air inside the bottle was being heated, the egg was placed over the opening of the bottle. The flame went out and the air inside the bottle started to cool. As the air cools, it gets smaller, reducing the pressure in the bottle. The egg acts as a cork, sealing the top of the bottle to keep air from coming in to balance the pressure. Instead, the higher outside pressure pushes the egg into the bottle. It was amazing.  We have so much fun learning about science with Zosia's mom.
