This lesson, if well planned out and conducted properly, addresses every component of the benchmark it is intended to cover. It involves a whole-group segment, during which the teacher provides a demonstration for students to observe. It also involves a segment that requires the students consult other sources of information related to what they observed in making their hypothesis and planning their investigation. It also involves a group-learning segment, that can easily be adjusted to incorporate differentiated instruction to accommodate students with special needs, during which students conduct the investigation they planned. Finally, it also involves a segment that allows the students the opportunity to communicate the results of their investigation and to evaluate the results of investigations conducted by others. It may also involve another segment involving direct instruction of the components of the scientific method and practice opportunities for students to develop their understanding of these components if this is determined to be necessary based upon the results of the pre-lesson assessment.
