Extra Credit #3

Matching Match each description with the correct term. Gravitational Field the area around an object that pulls atoms together Magnetic Field the area around an object that produces a North and South pole Electrical Field the area around an object that produces a charge Draw it Draw the path that electrons take when two magnets are attracting and when two magnets are repelling. Draw it Draw arrows showing the path that electrons take in the circuit below. Sort Sort the following descriptions and examples into the correct column. Magnetism electrons emerge from the North pole and pulled into the South pole opposite poles attract and same poles repel this type of field force can cause other metals to act just like it clusters of atoms called domains are forced to align in particular metals due to this field force Electricity electrons move from the negative terminal of the battery to the positive terminal of the battery opposite charges attract and same charges repel this type of field force uses friction to transfer electrons a wire coil called a solenoid uses this field force to produce magnetism True Sort the following statements into either the True or the False column. True Earth's magnetic field and the magnetic field of a bar magnet have a North and South pole. Magnetic fields move from the North pole to the South pole False Earth's magnetic field emerges from the magnetic South pole When a magnet is moved closer to a ferromagnetic material it causes the domains to scatter. Which diagram correctly displays the magnetic field of a bar magnet and Earth? (Zoom in on each image to determine the correct answer.) A student completes 3 different activities. Which activity shows the balloons having the same charge? Activity 1 Activity 2 Activity 3 A student completes 3 activities using two balloons. What evidence supports that there is a non-contact force at work on the balloons? The balloons are not in contact and tend to move away from each other when both are rubbed with rubber. The balloons are not in contact and tend to move away from each other when both are rubbed with wool. The balloons are not in contact and tend to move close to each other when both are rubbed with a glass rod. The balloons are not in contact and tend to move close to each other when both are rubbed with wool. A student has two magnets like the ones below. How can the student arrange the magnets to feel the force of the magnetic field as a results of repulsion? A student suspends two inflated balloons from the ceiling. The student wants to show that a field exists between the balloons exerting forces on each other even though the balloons are not in contact. Which action will demonstrate that the balloons can either attract or repel each other? Push the balloons toward each other to generate a magnetic field. Place a magnet in between the balloons to generate a magnetic field. Cover one balloon with a cotton cloth to generate a gravitational field. Rub both balloons with a wool rag to generate an electric field. Matching Match each diagram of metal with the correct description. will not attract to a magnet will attract to a magnet aluminum will not attract to a magnet iron will attract to a magnet
