Students record the number of paper-clips the magnet can attract through each substance. Students use a magnet to stroke various metallic objects to determine which metals can be made into magnets. They demonstrate their scientific skills and processes by engaging in investigations, formulating questions, and constructing models to represent their ideas. To assess how students interpret their data and draw simple conclusions, the teacher helps students construct a bar graph using the data from the magnetic strength tests. Students identify greatest and least strengths and compare their results with those of other students.
Students draw conclusions from their results.
The teacher gives students a set of materials and asks them to classify the materials as magnetic or non-magnetic. Students provide a summary statement concluding which materials are magnetic and which are non-magnetic. To assess how students describe the characteristics of magnetic fields, the teacher asks them to draw the results of sprinkling iron filings over a piece of paper or transparency with different arrangements of magnets. These resources are those that have been evaluated since 1992. A complete list of resources to support this organizer can be found in Appendix B .
