Magnets & Motors
Making a Motor
Students graph their data and discuss their results as a class.
Explaining: Use evidence from scientific investigations to think critically and logically to develop descriptions, explanations, and predictions (INO3 2.1.3).
Communicating: Communicate scientific procedures, investigations, and explanations visually, orally, in writing, with computer-based technology, and in the language of mathematics (IN05 2.1.5).
Use graph paper to record and describe data. Communicate results of experiments visually, orally, and through discussion.
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.
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.
