Five-E Organization

Teacher Does Student Does

Engage: Learning Experience A) Common/Unique Game: Given a topic, students in a group will first try to come up with a word that the other groups might think of that relates to the topic of reproduction. Next, students in a groupwill try to come up with a unique word that is different from the other groups. (repeat 2-3 cycles) Questions * Can organisms reproduce by themselves? * If yes, how? (Ask them if they can think of any organisms that reproduce asexually.) * If no, explain why you think this is so.

Hoped for student response Students will be able to list basic ideas that pertain to reproduction; especially asexual reproduction Expected Students Response Various responses. Students are to have a wide range of responses depending on their knowledge of reproduction; especially asexual mechanisms of reproduction.

Evaluate

Note whether all students are actively participating and interested. Ask probing questions to determine students’ understanding of asexual reproduction.

Explore: Learning Experience Watch the video: Asexual Reproduction and Alteration of Generations. After every segment, ask questions that allow discussion of the video. As a team, students will identify advantages and disadvantages related to asexual mechanisms of reproduction. To develop their thinking, students conduct research, using printed and electronic resources. Questions * Questions to be addressed during the video.

Hoped for Student Response All students will understand and know what to do and will be engaged during the video and discussion. Students will be able to come up with an experiment that would adequately test their hypotheses and be able to explain their experiment idea to the rest of the class.

Evaluate

Monitor students to determine whether all successfully complete the activity.

Ask inquiring questions to see if they comprehend what they are doing. Check that they are filling out the data sheet(s) as they are carrying out the lab.

Explain. Learning Experience: Someone from each group will describe the experiment they would use to test their hypotheses. After students share their ideas, go over the general functions importance of asexual reproduction Questions * On the basis of student observations ask students to develop their own hypothesis about the mechanism of flower pollination.

Hoped for Student Response Students will be able to design several hypotheses based on their observations from the video. Expected Student Response Students will rely on information and knowledge obtained from this particular lesson to answer the following questions

Evaluate

During the explanation take a vote to get a scheme of how many students actually understand the concepts covered so far. Teacher walks around the room to hear students discuss their thoughts. Collect and grade data sheets form the laboratory investigation.

Extend/Elaborate: Learning Experience * Talk about ways sexual reproduction might be better than asexual reproduction or vice versa.

Hoped for student response Various answers

Evaluate

Note students’ contributions to various extensions to make sure that they understand the concept of asexual reproduction.

“Create an Experiment”

With the information discussed from the video, create an experiment to test your hypothesis for advantages and disadvantages of asexual reproduction. The purpose has already been given to you. Be sure to include your hypothesis, materials needed and detailed steps on how to perform your experiment. If necessary, continue onto the back. When you are done, make sure to summarize your experiment on the transparency so that you can present it to the class.

Purpose: To test and identify advantages and disadvantages related to asexual mechanisms of reproduction.
