Reflection: Debate That's Not a Plant, It's a Weed! Discovering Functions of External Plant Parts; What Makes a Plant a Plant? - Section 1: That's not a plant! That's a Weed!


I realized after looking at the last assignment that many students could not classify the difference between a flowering, seed bearing or non seed bearing plants. Most of them have  not had much experience looking at plants in their yard before and noticing what grows there. To me, science begins in our backyards. As children, we should be noticing birds, plants and things we find after we turn over rocks. I realized that many of my students have spent a tremendous time indoors, do not participate in gardening nor have awareness of the nature that is about them. It is my hope that through this lesson they develop new eyes and understanding of how to classify a plant.

In the lesson prior to this, students were introduced to seed bearing and non seed bearing plants. We discussed conifers and spore producing plants. The assignment was to find three plants and classify them as flowering, seed bearing or conifers.

For example, one student on his assignment had listed: pine tree- conifer

                                                                                 weeds-- weeds

                                                                                 dandelion-- weeds

When I surveyed the classroom, students thought that weeds are a classification of their own. This little debate was very important to help them begin to distinguish the meaning of "plant" and help them understand what they would be exploring today, and how we can understand the function of the external parts of a plant.

That's Not a Plant, It's a Weed! Discovering Functions of External Plant Parts; What Makes a Plant a Plant?

Unit 6: Plants: Structures and Processes
Lesson 4 of 14

Objective: SWBAT identify external structures of plants and describe their function.

Big Idea: Using data and prior knowledge, students use Educreations to explain their observations, measurements and understanding of various plant's external parts and how they help the plant survive in its environment.
