Electronic balloon poppers

  1. 1. Making an Electric Balloon Popper 9th Annual Day of the Teacher Conference March 26, 2011 CSUEB Concord Campus Charles Reynes Elementary Science Specialist Castro Valley, USD
  2. 2. Making an Electronic Balloon Popper <ul><li>Materials </li></ul><ul><li>Safety glasses are necessary </li></ul><ul><li>A balloon (large for demonstration, small for group work.) </li></ul><ul><li>#3 steel wool </li></ul><ul><li>Masking tape </li></ul><ul><li>Aluminum foil </li></ul>This activity came from TOPS Learning Systems, www.topscience.org They are a great resource for cheap science thrills.
  3. 3. Making an Electronic Balloon Popper <ul><li>Cut the aluminum foil into two one-inch strips. </li></ul>
  4. 4. Making an Electronic Balloon Popper <ul><li>Tape the strips together. </li></ul><ul><li>Leave a small (2mm) gap between the strips of aluminum foil. </li></ul>
  5. 5. Making an Electronic Balloon Popper <ul><li>Connect the strips of aluminum foil with a very thin strand of # 3 steel wool. </li></ul><ul><li>Hold the strand of steel wool in place until the device is attached to a balloon. </li></ul>
  6. 6. <ul><li>Tape the device to the side of a balloon. </li></ul><ul><li>(Note: the side of a balloon has the greatest tension.) </li></ul>Making an Electronic Balloon Popper
  7. 7. <ul><li>Connect the aluminum strips to a power source such as a hand crank generator or several D-cells in series. </li></ul><ul><li>BOOOOOMMM! </li></ul>Making an Electronic Balloon Popper
  8. 8. <ul><li>Why did the balloon pop? </li></ul><ul><li>Challenge students to pop two balloons at the same time. (series and parallel circuits) </li></ul><ul><li>Draw a diagram of the balloon popper. </li></ul><ul><li>Sequence the process. </li></ul><ul><li>Compare and contrast the electric balloon popper with a fuse. </li></ul>Teaching with an Electronic Balloon Popper
