This week, the students are investigating the properties of various minerals. On Tuesday, we practiced our observation skills by describing minerals based on their color, size, texture, transparency, and mass. On Thursday, we will testing each of the four minerals for hardness, a key property in mineral identification. Our test will include attempting to scratch each mineral with a fingernail, a nail, and a paperclip, then recording results and interpreting data. Key questions to ask students: What were some observations you made about the minerals? Which one was the hardest? The softest? How could you tell?
Have a wonderful break, everyone!
