How Plant Seeds Travel the World

All plants start as seeds, and they can travel all over the world in lots of different ways. They might even hitch a ride on you!SOURCES:First Grade Next Generation Science StandardsCrosscutting Concept: Structure and Function: The way an object is shaped or structured determines many of its properties and functions.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 StandardsCrosscutting Concept: Structure and Function: The way an object is shaped or structured determines many of its properties and functions.Disciplinary Core Idea:LS2.A: Interdependent Relationships in Ecosystems - Plants depend on water and light to grow (2-LS2-1). Plants depend on animals for pollination or to move their seeds around (2-LS2-2).Performance Expectation:2-LS2-1 Plan and conduct an investigation to determine if plants need sunlight and water to grow.2-LS2-2 Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.
