Best Examples of Thematic Unit Plan Examples on Plants for K–6 Classrooms

Plants are a teacher’s best friend when it comes to thematic units. They’re everywhere, they’re observable over time, and they connect naturally to health, food, climate, and culture. The best examples of thematic unit plan examples on plants take advantage of that real-world relevance and turn it into rich, cross-curricular learning.

In 2024–2025, many districts are pushing for more inquiry-based science, STEM integration, and place-based learning. Plant units check all those boxes: students can design investigations, collect data, and connect what they see in the schoolyard or at home to bigger environmental and food-system questions. Current standards, like the Next Generation Science Standards (NGSS) in the U.S., emphasize understanding ecosystems, life cycles, and human impacts on the environment, all of which fit beautifully into plant themes. You can explore NGSS life science standards here: https://www.nextgenscience.org/.

Below are several real examples of thematic unit plan examples on plants, organized from early elementary to upper elementary. Use them as templates, mix and match ideas, and adapt them to your context.

Example of a Kindergarten–Grade 1 Plant Unit: “Living Things All Around Us”

This is one of the most approachable examples of thematic unit plan examples on plants, perfect for young learners just starting to notice the natural world.

Big idea: Plants are living things that need water, air, light, and space to grow.

Core subjects blended: Science, language arts, early math, art.

Sample learning goals

Students:

• Sort objects into living and nonliving.
• Identify basic plant parts (root, stem, leaf, flower).
• Describe what plants need to grow.
• Use simple sentences and drawings to share observations.

Key activities

• Plant or Not? Sort: Students examine pictures or real objects (rock, leaf, stuffed animal, seed, plastic flower) and sort them into “living” and “nonliving.” They justify their choices orally.
• Seed-in-a-Bag Observation: Each child gets a bean seed in a damp paper towel inside a clear bag taped to the window. Over 1–2 weeks, they draw what they see and dictate or write short labels like “root” or “sprout.”
• Plant Needs Experiment (Simple Version): Set up three plants: one with no water, one with no light, and one with both. Students predict what will happen and check in daily.
• Literacy tie-ins: Read-alouds like From Seed to Plant by Gail Gibbons or Planting a Rainbow by Lois Ehlert, followed by shared writing: “Plants need ___.”

This early-grades example of a thematic unit plan on plants builds the foundation for later, more complex units while staying very hands-on and concrete.
