Teaching Aids
2. Smart Board
3. Paper for students to use to construct a Venn diagram comparing and contrasting sexual and asexual reproduction.
4. Powerpoint
5. After the powerpoint and a reading of the textbook, students will be given the following worksheet to complete for homework. The teacher will go over the assignment with them the next day.
Class Projects
Students are to prepare a report listing 5 organisms that use asexual reproduction, and 5 organisms that use sexual reproduction. The report is to include the scientific name of the organism and a photo of the organism.
