The CyberPad module on magnetism has also been aligned with the FOSS curriculum, as is shown below. While you do not need to acquire pre-made science kits, such as those offered through FOSS, students will need access to the physical materials listed for each day. For a list of all materials needed for the three modules, see physical materials here. Whether students work with the physical materials individually or in groups is up to you, as is the size of the student groups. Ideally, however, students will be individually recording answers and observations with the CyberPad.

+ Focus Question 1: What materials are attracted to (pulled towards) magnets?
+ Focus Question 1: What materials are attracted to (pulled towards) magnets?
Learning Objectives: Aligns with FOSS Investigation 3, Part 1
1. Some materials have particles that are affected by magnets.
2. Iron is the only common metal that sticks to magnets.
Physical Materials:
For Each Group: magnet, paperclip, paper, nail, cardboard, straw
+ Focus Question 2: What makes a magnet magnetic?
+ Focus Question 2: What makes a magnet magnetic?
Learning Objectives:
The way iron particles are affected by magnets changes the properties of the larger material object. Those changes in the object cause it to be attracted to the magnet.
Physical Materials:
No materials required unless you want to provide supplemental activities.
+ Focus Question 3: What happens to the particles in an object when it is turned into a temporary magnet?
+ Focus Question 3: What happens to the particles in an object when it is turned into a temporary magnet?
Learning Objectives: Aligns with FOSS Investigation 3, Part 3
1. The particles in an iron object (the “mini magnets”) will change their orientation when exposed to a magnet/magnetic field.
2. The way iron particles are affected by magnets changes the properties of the larger material object. Those changes in the object cause it to be attracted to the magnet.
3. An iron object can be made into temporary magnets by bringing the object into a magnetic field or by stroking the object with a magnet.
Physical Materials:
For Each Group: magnet, 2 paperclips, straw, bobby pin
+Focus Question 4: What happens when two or more magnets interact?
+Focus Question 4: What happens when two or more magnets interact?
Learning Objectives: Aligns with FOSS Investigation 2, Part 3
1. Unlike poles attract, like poles repel.
2. The orientation of the N and S sides of the magnet matches the orientation of the mini magnets.
Physical Materials:
For Each Group: Two donut magnets, pencil
+ Focus Question 5: Can magnets work at a distance to attract objects?
+ Focus Question 5: Can magnets work at a distance to attract objects?
Learning Objectives:
Magnetism can work at a distance and through objects (e.g., cardboard).
Physical Materials:
For Each Group: donut magnet, paperclip, cardboard, paper, aluminum foil
+ Focus Question 6: What happens to the force of attraction of a magnet as the distance from it changes?
+ Focus Question 6: What happens to the force of attraction of a magnet as the distance from it changes?
Learning Objective: Aligns with FOSS Investigation 2, Part 1
Simple circuits consist of an energy source (e.g., battery) that is connected to an energy converter (e.g., light bulb) by conductors (e.g., wires).
Physical Materials: 1 flashlight with 2 D cells, rulers, wire stripper, 1 incandescent bulb
For Each Group: 2 D cells, 2 light bulbs, short striped wires (20 gauge, 15 cm long)
Learning Objectives:
1. Magnetism works at a distance, and gets weaker as the distance from a magnet increases.
2. It takes more force to attract more paperclips, less force to attract fewer paperclips.
Physical Materials:
For Each Group: ruler, (at least) 4 magnets, (at least) 8 paperclips
