This science lesson was created to foster the critical thinking skills of students and enhance their ability to working in cooperative learning groups and share ideas and information in a supportive setting. Knowing that every teacher has an individual teaching style and faces challenges unique to their setting this lesson was developed to allow you to make modifications necessary to address your students’ strengths and challenges. I have included several modifications that can be used for this lesson but allowed enough flexibility for you to make additional modifications. The modifications to this lesson are only limited by your imagination. Please feel free to “take ownership of this lesson” for the benefit of your students.
