Magnetic Mystery

  1. 1. Magnetic Mystery<br />Brooke Icenogle<br />
  2. 2. Science Standard<br />4.3.15 Demonstrate that without touching them, a magnet pulls all things made of iron, and either pushes or pulls other magnets. <br /><br />
  3. 3. Definitions:<br />Magnet: an object than can attract other objects that are made up of iron, steel, or alloy. <br />Pole: one of the two ends of a magnet where the magnetism seems to be concentrated <br />
  4. 4. Background Information<br />Magnets are a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other materials like iron and attracts or repels other magnets.<br />
  5. 5. Purpose and Materials<br />The purpose of this experiment is to demonstrate that without touching, magnets either push or pull other magnets. <br />Materials needed:<br /> - Bar magnets, tape, small sticky notes, construction paper, crayons or markers, and science journal<br />
  6. 6. Science Journal<br />In your science journal, please reflect on the following:<br />Do magnets attract everything?<br />Are some objects easier to pick up with magnets?<br />Which material do you think the magnet will pick up the easiest? <br />After the experiment we will go back over your answers to see if they have changed any. <br />
  7. 7. Magnet Models <br />In this activity students will be modeling how magnets attract and repel one another. <br />Each student will receive a piece of construction paper.<br />Half of the class will write “N” on their chest, and the other half “S” and tape them to their chest. <br />Students will then move slowly around the room interacting as magnets would. <br />Once a North and South are attached, they have to remain that way until the teacher gently pushes them apart. <br />
  8. 8. Magnetic Mystery<br />Students are divided into groups of two, and each pair are given two bar magnets. One with covered ends and the other uncovered. <br />Ask students what the difference is between the two magnets and explain why the paper is covering the ends. <br />The goal is to determine the correct labeling of each pole. <br />Students will create a plan to test and determine what each end is and record it in their science journals.<br />Once ends have been determined, label them N or S and record result in journal. <br />
  9. 9. Magnet Test<br />In the box there are several different materials that are listed on the chart provided. <br />Students are to take the bar magnets provided in the box and test the various materials using both the North and South ends of the magnet. <br />Using the chart, record results<br />
  10. 10. Assessment<br />In the science journal, answer the following questions: <br />Do magnets pull all things made of iron without touching them? <br />Which materials were the magnets attracted to the most? <br />Were your predictions correct at the beginning of the experiment?<br />What did you observe when you placed two magnets next to each other?<br />Why do magnets push or pull other magnets<br />
