Pōhaku (Rocks)

Culture

Pōhaku of Hawai‘i

Across the Pacific Ocean, islands are often composed of volcanic rock, providing the very foundation to support life on land in the midst of the largest ocean on the planet. Lava rock, often referred to in ʻŌlelo Hawai‘i (Hawaiian language) as pōhaku, is not only the core of our islands, but a core resource for many purposes in Hawaiian and Oceanic culture.

Science

Pōhaku: Rocks, Stones, & Geology

There are many different rocks in the world. And each type behaves differently under different conditions. Pressure, heat, and erosion are just a few of the conditions that can be applied to rocks, and they can become different types of rocks according to the Rock Cycle. Check out the PODCAST and Rock Cycle Game to learn more about the process of the rock cycle and the different types of rocks it produces before creating your very own edible rock cycle!

Rock Cycle Lesson Plan

In this lesson, students will explore theories of island formation based upon evidence in the geosphere. They will investigate Hawaiian igneous rock by participating in hands-on activities with rock samples and using models to demonstrate the rock cycle.

Pōhaku: Rocks in Space

There are many different types of rocks in space, from asteroids to moons to planets. Here are some resources to help you learn about them!

Asteroid Mining Activity

In this activity, learners will imagine the challenges and opportunities of asteroid mining. Learners will draw their own asteroid mining machines, and consider how these devices would extract, process, and return mined materials to Earth. They can also assume roles assigned by the activity’s “challenge cards,” and imagine what concerns or priorities they might have as a scientist, explorer, lawyer, or engineer. Download all four files to do the activity! Recommended for ages 4 and up.
