Flower Dissection Lab

This is a teacher-created website with several resources for labs and activities. The introduction explains the definition of many terms. There is a brief overview of the dissection, which students are instructed to read. The directions are easy to follow and students are given an Observation Chart where they can record their observations (you must scroll all the way to the bottom to access it). Students are instructed to tape parts of their flower to their paper on the section provided. This is a well-developed lab with appropriate information and explicit directions.
