How to Use the Rock Classification Gizmo to Learn About Rocks
Rocks are natural substances that are made up of one or more minerals. There are three main types of rocks: igneous, sedimentary, and metamorphic. Each type of rock has different characteristics and forms in different ways. In this article, we will show you how to use the Rock Classification Gizmo to learn about these three types of rocks and how to classify them.
What is the Rock Classification Gizmo
The Rock Classification Gizmo is an online interactive tool that allows you to explore different types of rocks and their features. You can use the Gizmo to:
Examine 12 different rock samples and observe their textures, colors, and compositions.
Classify each rock sample as igneous, sedimentary, or metamorphic based on its characteristics.
Learn about the common characteristics of each type of rock and how they form.
Answer questions and complete activities to test your understanding of rock classification.
How to Use the Rock Classification Gizmo
To use the Rock Classification Gizmo, you will need a computer or a tablet with an internet connection and a web browser. You can access the Gizmo from this link: https://www.explorelearning.com/index.cfmmethod=cResource.dspDetail&ResourceID=1076. You will also need a student exploration sheet and an answer key, which you can download from the same page.
Once you open the Gizmo, you will see a screen like this:
The Gizmo has four main parts:
The SAMPLES pane, where you can select a rock sample to examine.
The CHARACTERISTICS pane, where you can see the features of the selected rock sample and compare it with other samples.
The CLASSIFICATION pane, where you can classify the selected rock sample as igneous, sedimentary, or metamorphic based on its characteristics.
The QUESTIONS pane, where you can answer questions and complete activities related to rock classification.
How to Classify Rocks Using the Gizmo
To classify rocks using the Gizmo, you need to follow these steps:
Select a rock sample from the SAMPLES pane by clicking on it. You can use the arrows to scroll through the samples.
Observe the texture, color, composition, and other features of the selected rock sample in the CHARACTERISTICS pane. You can use the magnifying glass to zoom in or out on the sample. You can also turn on Show common characteristics to see a list of typical features for each type of rock.
Based on the characteristics of the selected rock sample, decide whether it is an igneous, sedimentary, or metamorphic rock. You can use the definitions and examples in the CLASSIFICATION pane to help you. Click on the appropriate button to classify the sample.
If you are correct, you will see a green check mark and a brief explanation of why your answer is correct. If you are incorrect, you will see a red X and a hint to help you correct your answer.
Repeat steps 1-4 for all 12 rock samples. You can use the Reset button to start over at any time.
After you have classified all 12 rock samples, you can check your progress by clicking on Show summary in the CLASSIFICATION pane. You will see a table that shows how many samples you have correctly classified for each type of rock.
