In this video, Jessi and Squeaks will show you how a tiny seed can grow into a big plant. A seed is made up of three parts. An outer shell called the seed coat, a tiny baby plant called an embryo, and plant food for the embryo called endosperm. When a seed gets planted into the ground, it will go through a growing process called germination. Germination happens inside the seed, and with just the right combination of temperature, water, and sunlight the embryo will start to grow. The roots will grow down into the soil and start absorbing water and food from the soil, and the shoot pushes up towards the sunlight. It continues to grow and eventually produce seeds of its own.
This video satisfies the 3-LS1-1 requirement for third-grade science proficiency.
Students who demonstrate understanding can:
3-LS1-1. Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
