Lots of science experiments for December! We are still talking about density and signs of a chemical change. Alana won a prize from Miss Sandy today by identifying the 4 signs of a chemical change and that baby oil is less dense than water. This week we made a snow storm in a jar and winter slime! 4 signs a chemical change is happening: 1.) forming an unexpected solid (precipitate) 2.) unexpected temperature change 3.) unexpected color change 4.) bubbling (but not boiling or air bubbles!)
