Meanwhile in another Science class

While the other kids were doing the Materials and Structures unit, Christine was doing some cool science learning of her own. She made her own crystals and was able to compare the surface of the crystals to some rocks.

She also studied chemical weathering by putting limestone and another stone in vinegar to watch the chemical reaction of the limestone to the vinegar. She also put a ball of steel wool in the vinegar and a few days later the steel wool was completely disintegrated!

(this picture is after 1 day, we forgot to get a picture of the totally disintegrated stage)
