In deze activiteit, zullen de studenten de relatie tussen wetenschappelijke concepten over vulkanische activiteit en onze wereld te identificeren.
Het voorbeeld beschrijft de relatie tussen vulkaanuitbarstingen en huidige topografie van Hawaii.

Bring science to life by involving students in a hands-on volcano model activity. Building a simple model helps students visualize volcanic processes and connects classroom concepts to the real world.
Collect baking soda, vinegar, dish soap, red food coloring, and a small bottle or cup. These household items make it easy and safe for students to create their own eruptions.
Have students mold clay, playdough, or paper mache around the bottle to form a volcano shape. This step encourages creativity while reinforcing the structure of real volcanoes.
Ask students to add baking soda inside the volcano, then mix vinegar, dish soap, and food coloring before pouring it in. Watch the reaction! Discuss how the 'lava' flow models real volcanic eruptions and shapes landforms.
Prompt students to compare their model’s lava flow to Hawaii’s volcanic activity. Discuss how repeated eruptions can create new land, just as in the classroom model. This connection deepens understanding of volcanic processes and topographical change.
Volcanic eruptions build up the Hawaiian Islands by adding new land through flowing lava. As lava cools, it forms rocks and sand, continually changing the islands' topography and coastline.
Volcanoes help shape Earth's surface by creating mountains, islands, and valleys. Their eruptions deposit new materials, which alter the land's form over time.
The type of volcanic eruption determines the lava flow's appearance. Some eruptions create sharp, rough rocks, while others produce smooth, billowy surfaces as the lava cools differently.
Use simple models or diagrams, like a spider map, to show how volcanic activity builds islands and changes landscapes. Relate real-world examples, such as Hawaii, for better understanding.
Try creating a spider map linking volcanoes to landforms, use videos of Hawaiian eruptions, or have students compare different lava types using photos and simple experiments.
