Plant Needs

In this series of Lessons to Grow By, we are exploring plant needs. For healthy growth and development, plants must obtain just the right amounts of light, water, air, and nutrients and they also need space to grow. These five requirements are the basic needs for all plant life. Fortunately for our world full of diverse environments, different plants need different amounts of each of these essentials so there are plants well adapted to grow in almost all environmental conditions. Through these activities, kids will investigate plant needs to better understand how to be take care of their green friends while also gaining a deeper appreciation for how the living and nonliving elements in an ecosystem work together.

The lesson sets below are written for grades 3-5, but are easily adapted up or down. We also have this related lesson for early childhood, appropriate for younger learners: Early Childhood Plant Needs Activity
