Rock Dominoes

Hopefully you have heard that Room 221 scientists are studying rocks and minerals! We have been learning to look closely at rocks and use precise words to describe their characteristics. Yesterday we learned some fancy vocabulary words that describe rocks. Your third grade scientist can tell you that we can describe a rock's luster. Luster tells you how shiny a rock is. Third grade scientists can also tell you that we can describe a rock's texture. Texture describe how a rock fees.

We ended the lesson playing a game of Rock Dominoes. I held up a rock. Third grade scientists had to choose a rock that had the same property as the first rock. For example, they might start with a rock that was pointy. If a child had a different rock that was also pointy, they could put it next to the first rock. They would have to explain that both rocks share the property "pointy." We continued the game with each rock. Children could choose a similar property or choose a different similarity.

You can even play this game at home! :o)
