Investigate the rock cycle. What is a rock? What is the rock cycle? How do rocks form? How are they classified? Your students will answer these essential questions as they conduct a series of hands-on activities. Using the set of rock specimens included, they will observe the distinct characteristics of each type of rock and explore the igneous, sedimentary and metamorphic processes of rock formation. Your students will Understand the processes that form igneous, sedimentary and metamorphic rocks. Identify rocks by their physical characteristics. Classify igneous rocks as extrusive or intrusive. Classify sedimentary rocks as clastic, organic or chemical. Classify metamorphic rocks as foliated or nonfoliated. Model the effects of metamorphism on rocks. Relate different types of rocks to the processes of the rock cycle. Class Size: 40 Students. Grades: 7-10.

Borosil brand pipettes are manufactured from specially selected heavy-wall machine-drawn borosilicate accurate bore glass tubing. They have precision formed jets and bevel ground ends to resist chipping. The graduation marks are in durable white enamel or amber stain, both are resistant to normal laboratory agents and repeated washing. All the pipettes are individually measured and then marked. Accuracy is ensured between any two readings, because of uniformity of bore. The pipettes can be autoclaved and if necessary can be flamed for sterilization.
