,Teachers and parents: scroll down to check out the Next Generation Science Standards (NGSS) for this episode! Platypuses are so funny, it looks like someone made them up as a joke. But they're real animals! Join Jessi and Squeaks to learn about how amazing platypuses really are! Hosted by: Jessi Knudsen Castañeda (she/her/they/them) 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 Idea: 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). Performance Expectation: 2-LS4-1. Make observations of plants and animals to compare the diversity of life in different habitats. ---------- Love SciShow Kids and want to help support it?
