Rock Types

Examine  the three types of rocks, sedimentary, igneous, and metamorphic.

Rocks are all around us, forming the ground we walk on and the mountains we see. In the Webelos Earth Rocks! Adventure, scouts learn about three main types of rocks: sedimentary, igneous, and metamorphic. Each type of rock is formed in a different way and has its own unique features.

  • Sedimentary Rocks: These rocks are made from pieces of other rocks, sand, or even shells. Over time, these materials pile up in layers and harden into rock. Examples include sandstone and limestone, which can often be seen in cliff faces or canyons.
  • Igneous Rocks: Formed from cooled lava or magma, these rocks can be found where volcanoes are present. When lava cools quickly, it turns into rocks like basalt. If it cools slowly, it becomes granite, which is often used in countertops.
  • Metamorphic Rocks: These rocks start as one type and change into another under great heat and pressure inside the Earth. Slate, which is used in roofing, and marble, used in sculptures and buildings, are examples of metamorphic rocks.

Here are some options for fulfilling Webelos Earth Rocks! Adventure requirement 1:

What’s Inside a Rock

Find a rock, safely break it apart and examine it.

Finding and breaking apart a rock is an exciting way to see what’s inside. This activity helps Webelos learn more about the structure and composition of rocks. It’s important to do this safely and responsibly.

  • Choose the Right Rock: Find a rock that is not too large; something you can easily hold in your hand is perfect.
  • Wear Safety Gear: Always wear safety goggles to protect your eyes from flying pieces. Gloves are also a good idea to protect your hands.
  • Use the Right Tools: Use a light hammer and a chisel to gently tap on the rock. Don’t hit it too hard, as the goal is to carefully break it open, not smash it into powder.
  • Examine the Pieces: Look at the broken pieces with a magnifying glass. Notice any grains, crystals, or layers in the rock.

Here are some options for fulfilling Webelos Earth Rocks! Adventure requirement 2:

Testing Mineral Hardness

Make a mineral test kit and test minerals according to the Mohs scale of mineral hardness. Using the rock cycle chart or one like it, discuss how hardness determines which materials can be used in homes, in landscapes, or for recreation.

Understanding mineral hardness helps us know how durable materials are and where they can be used effectively. In the Webelos Earth Rocks! Adventure, scouts make a mineral test kit and use the Mohs scale to test hardness. This scale ranks minerals from 1 (softest) to 10 (hardest).

To make a mineral test kit for the Mohs scale, you will need a few simple materials. First, you will need some minerals to test. You can use rocks from your rock hunt or buy a mineral kit from a store. Next, you will need a few items to test the minerals. To test the hardness of a mineral using the Mohs scale, you need to scratch the mineral’s surface with a mineral or object of a known hardness. You can use items like a nail, a penny, a glass plate, and a steel file.

Here’s how to test for each level:

  1. Talc: Use your fingernail to scratch the mineral. At this level, your fingernail easily leaves a mark.
  2. Gypsum: Use your fingernail to scratch the mineral. Your fingernail barely leaves a mark.
  3. Calcite: Use a copper penny to scratch the mineral. If it barely leaves a mark, the mineral is softer than calcite.
  4. Fluorite: Use a knife or a file to scratch the mineral. You easily make a mark with one of these items.
  5. Apatite: Use a knife or a file to scratch the mineral. You barely make a mark at this level.
  6. Orthoclase feldspar: Use a piece of glass to scratch the mineral. If the knife or file doesn’t leave a mark, but the glass does then you are at this level.
  7. Quartz: Use a piece of quartz to scratch the mineral. If it leaves a mark, the mineral is softer than quartz.
  8. Topaz: Use a piece of topaz to scratch the mineral. If it leaves a mark, the mineral is softer than topaz.
  9. Corundum: Scratch a piece of topaz with the mineral. If it leaves a mark on the topaz, the mineral is at this level.
  10. Diamond: Use a diamond to scratch the mineral. If it leaves a mark, the mineral is softer than diamond.

Using the rock cycle chart, discuss how the hardness of these materials affects their use in everyday life. For example, softer minerals may be used in landscaping because they wear down easily, while harder minerals are better for countertops in homes because they resist scratching.

Here is an option for fulfilling Webelos Earth Rocks! Adventure requirement 3:

  • Mineral Lab
    • Cub Scout study and share observation of the mineral test.
    • Supplies: penny, small piece of glass, piece of unglazed tile, metal file, eyedropper, safety glasses, minerals to test (talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum), small bottle of vinegar, Webelos handbook, paper
    • indoor, moderate energy, one week prep
