The Glencairn Elementary fourth grade classes had just finished a lesson on states of matter. To provide some fun supplementary lessons, YCC brought hands-on demos about the states of matter. We talked about phase changes and froze rubber ducks with liquid nitrogen. The students were asked to explain the properties of goop (cornstarch and water) and slime (borax-glue mixture) and classify them as solids or liquids to practice being scientists.
