Both sections are subdivided into six lessons about topics including humans' relationship with plants, the soil, and the parts of plants. The students are led by the characters Bud, Sprout, and Professor LePlant to find clues, do experiments, and solve problems as they journey into the world of plants. They see the goals and main ideas for each lesson, are presented the background facts to help them solve the plant mysteries, and get the instructions for the hands-on activities. Both individual and group assignments are incorporated into the activities. The teachers' guide provides classroom management tips, background information, and extension ideas.
Teachers can also find lists of additional resources related to each of the lessons.
One lesson about soil asks students to consider what is in soil and what about it makes it important for plant growth. They are given an opportunity to identify foods that are grown underground, experiment with soil substitutes, and perform activities in which they set up a compost box with red worms. The teacher's guide describes the components and characteristics of soil, explains the soil activities, and offers questions that lead to deeper investigation of soil.
