Solids and Liquids
Our first grade science "states of matter" explorations provide children with an opportunity to observe what happens when solids and liquids are mixed together.
Objects such as craft sticks, cloth, beans, candy, rice and rock salt are observed and charted according to their properties. Afterwards the items are placed in water and we see what happens.
The following day when asked, "What happened?" our young scientists eagerly raise their hands to share their observations. Using their important scientific words they tell us...
"Some things dissolved!"
"They can melt!"
"It became crystals!"
"They can change to different colors!"
"Some things didn't change at all!"
But, my favorite observation, which came at the end of the discussion, came from one little girl whose statement was so obvious I didn't even think of it. She said, matter-of-factly,
"They got wet!"
