What are Stalactites and Stalagmites? | Let's Explore Caves! | SciShow Kids

After visiting Sam the Bat in his family’s cave, Squeaks is learning all about the rock icicles that are growing from the ceiling and the floor in the cave!

Hosted by: Jessi Knudsen Castañeda (she/her/they/them)

Teachers and parents: scroll down to check out the Next Generation Science Standards (NGSS) for this episode!

Second Grade Next Generation Science Standards

Disciplinary Core Ideas:

ESS1.C: The History of Planet Earth - Some events happen very quickly; others occur very slowly, over a time period much longer than one can observe (2-ESS1-1).

ESS2.A: Earth Materials and Systems - Wind and water can change the shape of the land (2-ESS2-1).

PS1.A: Structure and Properties of Matter - Matter can be described and classified by its observable properties (2-PS1-1).
Performance Expectations:

2-ESS1-1. Use information from several sources to provide evidence that Earth events can occur quickly or slowly.

2-ESS2-1. Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.

2-PS1-1. Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
