In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this activity, learners try to figure out who has their matching rock type by reading a description of their rock (no talking!).

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity, learners will learn how igneous rock, metamorphic rock, and sedimentary rock are formed as part of the rock cycle and that the same forces that produce/change rocks also produce/chan

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity, learners take core samples of candy bars with a straw and carefully observe & excavate their sample, modeled after what the NASA Perseverance rover will do on Mars.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then
