Our science experiment today was EGGseptional, EGGsiting, EGGselent!!
Critter & Freckles enjoying the EGGselent science experiment |
We studied how steam engines work (for Mike Mulligan and His Steam Shovel AND for our trip this week to Greenfield Village when we get to ride a steam train!!)
We took an old glass milk jar and placed it in a pan with water. We boiled the water and the jar. Filling the jar 1/2 full with the boiling water we CAREFULLY placed it on a hot pad. Dollar placed a peeled, hard boiled egg on top. A few minutes later the egg dropped into the jar!! When the steam evaporated, it created a negative pressure in the jar thus sucking the egg through the opening! Way cool!
