The oceans around Antarctica are cold, but full of life. Join Jessi and Squeaks to learn about the blubber of seals, the amazing antifreeze blood of fish, and the shrinking skills of krill.

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!

First Grade Next Generation Science Standards

Disciplinary Core Idea:

LS1.A: Structure and Function - All organisms have external parts. Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air (1-LS1-1).

Performance Expectation:

1-LS1-1. Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.

Second Grade Next Generation Science Standards

Disciplinary Core Ideas:

LS4.D: Biodiversity and Humans - There are many different kinds of living things in any area, and they exist in different places on land and in water (2-LS4-1).

ESS2.C: The Roles of Water in Earth’s Surface Processes - Water is found in the ocean, rivers, lakes, and ponds. Water exists as solid ice and in liquid form (2-ESS2-3).

Performance Expectations:

2-LS4-1. Make observations of plants and animals to compare the diversity of life in different habitats.

2-ESS2-3 Obtain information to identify where water is found on Earth and that it can be solid or liquid.
