INQUIRY INVESTIGATION SUMMARY
PART 1
Students observe that iron or steel objects in contact with a magnet become temporarily magnetic themselves. This induced magnetism disappears when the iron or steel object separates from the magnet. Students find out that the magnetic force acts right through materials, with the exception of iron.
INVESTIGATION 1: THE FORCE
Students find that objects that contain iron stick to permanent magnets; other objects do not. They discover that two magnets will either a�ract or repel one another, depending on their orientation. The agent responsible for this behavior is the magnetic force.
INVESTIGATING MAGNETS AND MATERIALS
• What kind of materials do magnets stick to?
• What happens when you bring two or more magnets together?
Time: 30–45 minutes
INVESTIGATING MORE MAGNETIC PROPERTIES
• How do magnets interact with other objects?
• Does an iron object have to touch a magnet to become a temporary magnet?
• Does magnetic force go through all materials?
Time: 30–45 minutes
BREAKING THE FORCE
• How can we measure the force of a�raction between two magnets?
Time: 50 minutes, in 1 or 2 sessions
Students use a balance and large washers to measure the force of a�raction between two magnets. They systematically investigate what happens to the force of a�raction as the distance between the two magnets increases. Students graph their results.
Students explore ways to detect the magnetic force. They find several ways to detect the force and to make it visable, using such things as compasses and iron filings.

Students explore simple electric circuits. They use trial and error to build a circuit that lights a bulb. They begin developing concepts about how connections must be made and how electricity flows through a circuit.
Students use a circuit base to build a circuit with a D-cell and a motor. They add a switch to the circuit to control the flow of electricity. Students learn the conventions for drawing schematic diagrams of circuits.
Students build a circuit to test whether objects are conductors or insulators. They search the classroom for insulators and conductors.
Students work with mystery boards to reinforce the concept of conductor and check their understanding of how electricity flows through a circuit.

INQUIRY INVESTIGATION SUMMARY
PART 1
BUILDING AN ELECTROMAGNET
• Can you make a magnet that turns on and off?
Time: 30–40 minutes
CHANGING NUMBER OF WINDS
• How does the number of winds of wire around a core affect the strength of the magnetism?
Time: 50 minutes, in 1 or 2 sessions
INVESTIGATING MORE ELECTROMAGNETS
• How can the strength of an electromagnet be changed?
Time: One 50-minute session or two 30-minute sessions
Students discover that, when current flows through an insulated wire wound around a steel core, the steel core becomes a magnet. They find out where to wind the wire on the core to produce the strongest magnet.
Students experiment to find out how the number of winds of wire affects the strength of magnetism. A�er collecting data for a 20-wind, 30-wind, and 40-wind electromagnet, students graph their results. They predict the strength of magnetism based on the graph.
Students propose other ways to change the strength of the electromagnet. A�er listing a set of variables, students plan and conduct an experiment.

Examples of questions students might generate for inquiry projects
• Part 3 of this investigation is an inquiry project. See investigations suggested in that part.
• A magnet can be made by winding an insulated wire around an iron core and running current through the wire.
• The magnetism produced by an electromagnet can be turned on and off.
• The greater the number of winds of wire around the iron core, the stronger the magnetism produced.
• A graph can be used to make predictions.
• There are many ways to change the strength of an electromagnet, including tighter coils, number of D-cells, and different wire gauge.
• Wire used to make an electromagnet must be insulated.
• All wire coils must be wound in the same direction.

GETTING READY1. SCHEDULE THE ASSESSMENT
You may need to give the assessment in two sessions: one for the performance items, and one for the multiple-choice/short-answer and narrative items. Read through Steps 2 and 3 below before deciding how you will proceed.
2. ADMINISTER THE PERFORMANCE ITEMS
The performance assessment is in two parts: one assesses understanding of magnetism and the other of electricity.
Individual Assessment. If you want students to work individually, you can assess up to sixteen students at a time. Set up eight identical stations for magnetism and eight identical stations for electricity around the room. Or set up both tasks at each station (eight stations, instead of sixteen). Students will need about 10 minutes to complete each task and to fill in the assessment sheet at each station. Send shi�s of students to the stations until all have had a chance to complete both tasks. Students waiting to take their turn at the performance tasks can be completing the multiple-choice/short-answer and narrative items, or working on some other quiet activity.
Collaborative-Group Assessment. If you don’t have time for each student to complete the performance tasks, have students work in groups. A�er the group completes the task, each student fills in his or her assessment sheet individually. The completed assessment sheets should reflect each student’s learning.
3. ADMINISTER THE MULTIPLE-CHOICE/SHORT-ANSWER AND NARRATIVE ITEMS
Assessment items in content areas such as science o�en require a fairly high level of reading. If you feel that students will have a difficult time reading the items on their own, you can read each item and its possible answers (when appropriate) aloud. Have students mark their answers and move on to the next item, working together through the assessment, item by item.
4. COPY ASSESSMENT SHEETS
Make copies of the assessment masters provided a�er this folio. Each student needs one set of sheets. Make a copy of the assessment chart no. 6 to record scores.

5. SET UP THE PERFORMANCE STATIONSSet up stations for the magnetism and electricity performance tasks as suggested below.
Magnetism Station• Put the two magnets on the table, away from the washers.
Electricity Station• Prepare the compasses by taping each to a small piece of
cardboard. Wrap an electromagnet wire around the compass and cardboard, leaving about 15 cm on each end for students to hook into a circuit. Tape the wire coil to the back of the cardboard to keep it secure.
• Put all equipment at the station, making sure none of the components are connected in any way.

PERFORMANCE ASSESSMENT ITEMS—Magnetism and ElectricityEND-OF-MODULE ASSESSMENT SCORING GUIDES
Performance Assessment Item—Magnetism
Score If the student... 4 writes detailed procedures and results; includes in
the response that he or she (1) tried to see how many washers one magnet picked up, (2) recorded that number, (3) repeated this for two magnets, (4) learned or confirmed that two magnets together are stronger than one.
3 writes brief notes that are accurate; presents all components above, but abbreviated.
2 fails to explain fully the procedure or results; appears to use the correct technique; misses one component above.
1 writes incomplete notes; gives flawed explanation. 0 does not complete the item, or gives information that
has nothing to do with what was asked.
Performance Assessment Item—ElectricityScore If the student...
4 draws an accurate schematic diagram using conventional symbols; notes that the compass needle moves when electricity is turned on; explains that the wire that has electricity flowing through it also has a magnetic field, and that the magnetic field around the wire interacts with the magnetic needle of the compass.
3 draws an accurate schematic diagram using conventional symbols; notes that the compass needle moves; explains that the wire must be magnetic.
2 draws a reasonably accurate diagram; notes that the compass needle moves; explains that magnetism is somehow involved.
1 draws a diagram with mistakes; notes that the needle moves, but cannot explain why.
0 does not complete the item, or gives information that has nothing to do with what was asked.

• Conducts electricity: basketball hoop, soup can, aluminum foil, bo�le cap, penny.
• Sticks to a magnet but does NOT conduct electricity: magnetite.
Narrative Items
Item 16 Magnet Interactions
Score If the student...
4 writes about logic used: if two white ends repel, but one of each color a�racts, then two gray ends should act like two white ends and repel; same poles (or sides) always repel, opposite poles always a�ract.
3 writes that the same ends always a�ract and opposite ends always repel, so the two gray ends will repel.
2 writes that the magnets will repel because sometimes magnets a�ract and sometimes they repel.
1 writes only that magnets repel.
0 gives the wrong answer (they a�ract); does not complete the item, or gives information that has nothing to do with what was asked.

Item 17 Double-Pole Switch
Score If the student...
4 explains that a closed circuit is made when the switch is closed in either direction: closed to the le� makes the bulb light and closed to the right makes the motor run; notes that the light and motor cannot run at the same time.
3 explains that a closed circuit is made by closing the switch in either direction: closed to the le� makes the bulb light, closed to the right makes the motor run.
2 explains only that the switch will work the light one way and the motor the other.
1 makes an error, such as saying that the motor and the bulb will run at the same time.
0 does not complete the item, or gives information that has nothing to do with what was asked.
Item 18 Troubleshooting an Electromagnet
Score If the student...
4 explains that the wire wrapped around the core needs to be connected to a D-cell in a complete circuit; suggests checking other factors that might influence success, such as making sure the wire is insulated and that the rivet is iron or steel; draws a diagram to show how to hook the electromagnet into the circuit.
3 explains that a source of electricity is missing; suggests adding a D-cell to make a complete circuit; suggests adding a switch.
2 suggests adding a D-cell or other source of electricity, but does not elaborate further.
1 makes a suggestion that is related to the problem, such as “wrap the wire more times” or “add a switch.”
0 does not complete the item, or gives information that has nothing to do with what was asked.
