Mitosis done in steps
Post a scenario on the board to have students begin thinking about the cell division process. An example would be: You sat at the park all day on a sunny June day. You forgot your sunscreen and got a pretty bad sunburn. Over the next few days your skin blisters and peels off. But there is new skin under the old damaged skin. How does that happen?
This hook gives students a real life reason to be curious about cell division. It is the perfect lead in to learning about mitosis and cytokinesis.
2 Direct Instruction
Students receive direct instruction via teacher created videos using Doceri. The content delivery method allows students to receive the information at their own pace. This can be done at home in a flipped classroom model or in class before the activity begins. Either way students are able to focus on the content without the full class distractions that may occur during a traditional lecture type content delivery method. Students are also able to rewind and re-watch the videos as often as they like to get the content explanation more than once.
3 Guided Practice
Students participate in a modeling activity to solidify the concept of mitosis. They use pipe-cleaners and chalk or large paper and markers to model each phase of mitosis. After modeling each phase, students use Skitch on their iPads to take pictures of the model. Using Skitch students are able to annotate the pictures. They also answer questions on a worksheet describing they stages as they progress through the activity.
4 Independent Practice
Students use anyone of multiple methods of creation to showcase their knowledge of the cell cycle. The students may choose to use iMovie, Garageband, or non-technology method such as a booklet. They can use the pictures they took and annotated using Skitch as their images for their iMovie project. Students must write a script describing what is happening at each stage of the cell cycle (including all the stages of mitosis). The completed project will be used to evaluate the students’ level of mastery and will also be available to use as a study tool.
Students will be asked a closing question – What happens to the two cells that were made after cytokinesis?
Have the students make the connection that both new cells begin the cell cycle. Then ask them how gamete cells are different than the somatic cells that were formed during mitosis and cytokinesis. These questions are asked using the Geddit app. Students are to type in their answers and then the teacher receives their responses.
