Lesson Summary In this lesson, students review the experiment they conducted in Lesson 10.  They graph their results and report them to the class.  The class compares each team’s findings.  Students attempt to make connections between what they found out and other students’ findings. Teacher Background This lesson gives students the opportunity to communicate what they have learned.  It is the occasion for presenting their findings graphically, applying mathematical skills, and making either written or oral presentations of the results of their group’s experiment, using language-arts skills. Once each group has presented its results to the class, the students then have time to think about the results and to try to synthesize them in to a more coherent view of electromagnetism. There are many possible ways for students to present their results.  Step 2 of the Procedure section shows a sample graph.  You could show students how to make this kind of graph or challenge them to find other techniques for presenting information. There are various ways in which students can present the results of their experiments: the choice is yours.  They might write up a group report and contribute a copy of it to a bulletin board on which all the reports are displayed.  In addition, you might ask each group to make an oral report to the class.  As an extra dimension to a presentation, you might suggest that the students pretend they are presenting a paper at a scientific conference.  You might challenge them to use visual aids and to adopt the language and study that they imagine scientist’s use at such conferences.  The audience could be challenged to behave appropriately and to try to ask the presenters probing questions. In whatever way you choose to have the students present their results, the products of their presentations should be kept in a portfolio prepared for each student.  A portfolio of work will be a useful way to assess the students’ progress at the end of the unit. Set-up/Management Tips Make copies of Activity Sheet 5 for the whole class. For each group, make a transparency of Activity Sheet 5. Overhead markers will also be needed. Optional materials include poster board or big paper for each group to present their results. You may need to review how to construct a graph. Decide how you plan to conduct this “conference”. It can be small or elaborate, depending on the amount of time you would like to spend. This is nice time to incorporate art into the unit if you have the time to spend. Literacy Support Students should also make sure they write at least a few sentences in their science notebooks describing what the graph shows.  See the Student Activity Book for Lesson 11. Scientific Vocabulary The following words are key vocabulary words that will be introduced in this lesson and reinforced throughout the unit: No new vocabulary introduced this lesson.
