  1. Make a Rock Collection

  2. Starting a Rock Collection • Materials: • Shoebox / Cardboard box / Egg carton • Hammer • Hand-lens • Knapsack/plastic bags/paper • Science Journal (Keep notes) • Index cards (Used as labels) • Black permanent marker

  3. How to Identify Rocks • Materials: • Textbook • Geological Map of Oahu • Resources from class • Use books & resources to identify, classify & describe the rocks. • Look for features by which the rocks can be put into categories.

  4. Where to Look • Quarries • Road cuts • Natural cliffs • Beach • Hills & Steep slopes • *Be careful when collecting rocks. Work with another person, if possible, and carry a first aid kit. Wear protective clothing--safety glasses, hard-toed shoes, hard hat, and gloves--when dislodging specimens. Avoid overhanging rock and the edges of steep, natural or quarried walls.

  5. Starting a Rock Collection • Labeling • Use marker to write a number on the rock • Science Journal • Create a data table • List the following data: • The number • Rock name • Date collected • Description of collection site

  6. Hints for Rock Collectors • Label specimens as they are collected. Identification can wait until later, but the place where the rocks were found should be recorded at once. Many collections have become mixed up because the collector did not do this. • Ask for permission to collect rocks on private property. The owners will appreciate this courtesy on your part.

  7. Hints for Rock Collectors • Do not collect rocks in national parks and monuments or in State parks; it is illegal. Similar rocks commonly crop out on land nearby. • Look for unusual rocks to study in large buildings or in cemeteries. Dimension stone blocks and monument stone are often transported long distances from where they are quarried. Polished stone sometimes looks different from unpolished rock. This provides good identification practice.
