Room 22 is wondering WHY???
Room 22 has been asking some questions about water recently. We’ve learned that rivers, lakes and streams contain freshwater and oceans and seas have saltwater. We read about how when water evaporates and the salt stays in the oceans and it only rains freshwater. We wanted to know what happens to objects in saltwater and freshwater? It turns out many objects end up floating when they are placed in saltwater. Our next question is why??
