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

It's almost Jack O' Lantern time! Which has Squeaks wondering why pumpkins get so big and other vegetables don't.

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:

LS2.A: Interdependent Relationships in Ecosystems - Plants depend on water and light to grow (2-LS2-1).

Performance Expectation:

2-LS2-1. Plan and conduct an investigation to determine if plants need sunlight and water to grow.
