- The Rock Cycle: Weathering, Erosion, Heat & Pressure, Melting, Cooling
- Rock Identification Tests: Mohs Hardness Scale, Streak Test, Acid Test
Lesson Structure
1. Introduction (10 minutes) – Direct Instruction
- Begin by asking: "What are rocks, and how do they change?"
- Introduce the three types of rocks (igneous, sedimentary, metamorphic) with real-life examples.
- Briefly explain the rock cycle and how rocks transform over time.
- Discuss how scientists identify rocks using tests like hardness, streak, and acid reaction.
Show the instructional video (5-7 minutes) to reinforce these concepts.
2. Exploration & Engagement (30 minutes) – Online Escape Room
- Guide students to the Crystal Cavern Quest online escape room.
- Students will solve puzzles, answer riddles, and complete challenges to discover, identify, and collect missing rock specimens.
- Encourage teamwork and discussion while navigating the adventure.
If students get stuck, remind them to use the Adventure Guide button to review information.
3. Assessment & Wrap-Up (20 minutes)
Escape Room Completion Check:
- Review the students’ progress in the escape room and discuss key takeaways.
- Ask reflection questions:
- What type of rock did you collect in the adventure?
- How do we classify rocks using scientific tests?
Optional Assessment Worksheet (Downloadable):
- Assign a worksheet with multiple-choice questions and short answers for extra assessment.
Conclusion
Encourage students to continue their geological adventure by exploring other rock specimens. Remind them that scientists like geologists are always making discoveries—and they just made their own in the Crystal Cavern Quest.
Students should log their collected specimen and challenge themselves to find more by completing additional Excavating Adventures.

Teacher Reference Guide: Rocks and Minerals
Rocks and minerals are the foundation of Earth’s surface and play a crucial role in shaping our planet. A rock is a naturally occurring solid made up of one or more minerals. Minerals are the building blocks of rocks and have unique properties that help scientists identify them. There are three main types of rocks: igneous, sedimentary, and metamorphic, each formed through different geological processes.
Igneous rocks form when molten rock (magma or lava) cools and hardens. If the cooling happens beneath Earth’s surface, the rock is called intrusive igneous rock and has large crystals due to the slow cooling process. If the lava cools quickly on the surface, it forms extrusive igneous rock, which has small or no visible crystals. Common examples include granite, obsidian, and basalt.
Sedimentary rocks are formed from layers of sediment, such as sand, silt, and organic materials, which compact and cement over time. These rocks often contain fossils, as they form in environments where plants and animals once lived. Sedimentary rocks provide a record of Earth’s history, preserving layers of past environments. Examples include sandstone, limestone, and shale.
Metamorphic rocks are formed when existing rocks undergo heat and pressure deep within Earth’s crust, causing them to change into a new type of rock without melting. This process, called metamorphism, alters the rock’s mineral structure and appearance. Common metamorphic rocks include marble, which forms from limestone, and slate, which forms from shale.
The rock cycle explains how these three types of rocks are continuously transformed through natural processes. Rocks can change from one type to another due to weathering, erosion, heat, pressure, and melting. For example, an igneous rock can be broken down into sediment and later compacted into a sedimentary rock. Over time, that sedimentary rock could be exposed to heat and pressure, transforming into a metamorphic rock. The cycle repeats as rocks continuously break down, change, and reform.
To classify rocks, scientists use rock identification tests based on a rock’s physical and chemical properties. One key test is the Mohs Hardness Scale, which ranks minerals from 1 (the softest, talc) to 10 (the hardest, diamond). The streak test helps determine a mineral’s true color by rubbing it against an unglazed tile to see the color of its powdered form. Another important test is the acid test, which is used to identify limestone and other carbonate rocks by adding a weak acid to see if the rock fizzes. These tests, along with observing a rock’s texture, color, and crystal structure, help scientists determine its identity.
In today’s lesson, students will explore these concepts through an interactive video and an engaging online escape room called Crystal Cavern Quest. The video will introduce key information, while the escape room will allow students to apply their knowledge to solve puzzles and complete challenges. The main mission of the escape room is for students to Discover, Identify, and Collect a missing rock specimen. They will navigate underground chambers, answer questions, and use problem-solving skills to unlock the final specimen.
After completing the escape room, students should log their specimen in their Specimen Log and reflect on what they have learned. For additional assessment, a downloadable worksheet is available to reinforce key concepts. Encourage students to continue their geological adventure by exploring other rock specimens and completing more Excavating Adventures to build their collection.
