Fourth Grade Studies Rocks and Minerals


047

Fourth graders have been studying rocks and minerals.  They have been able to learn about the properties of rocks that scientists use to identify specimens out in the field, and have collected their own rocks and tested them to help categorize them.  Students have been scratching rocks on streak plates to determine their streak (color of the mineral’s powder,)  determining a rocks density using water displacement method of calculating volume, and measuring mass on a triple beam balance.  To finish off the unit, each student received a geode to crack to see the tiny crystal wonderland within!  It was very exciting and definitely one of the student’s favorite topics of study.
