= Webquest 1: = ** The Task **
 * 1) Create a PowerPoint presentation sharing what you have learned after researching websites on different topics about electricity.
 * 2) You should have at least 20 slides.
 * 3) Use the websites listed below to combine information on:


 * Static Electricity
 * Series and Parallel Circuits
 * Electric Charge
 * Electric Current
 * Electromagnets
 * Conductors and Insulators
 * Magnets and Magnetic Fields

** The Process ** To capture pictures off the internet, **__right__** mouse click over the picture and save to the hard drive, the server, or a floppy disk. You may rename the file if you want to.**
 * 1) You will work together in teams of two.
 * 2) Each person on the team will contribute.
 * 3)  Decide how you are going to collect your information from the internet. ( note taking, copy and pasting into a Word Document, etc. You may want to capture pictures off the internet during your research to use in your finished product - see below for directions on how to do that.)
 * 4) ** At this point, share your information with your teacher before you continue. **
 * 5) Once you have the OK from your teacher, you need to research the areas listed above under the task section.
 * 6) Below you will find web sites to help you in your research:

 * MAKE A LEVITATING ORB!
 * [[image:http://www.sciencebob.com/graphics/watch_orb.gif width="233" height="122" link="http://www.sciencebob.com/experiments/videos/video-static_orb.php"]] [[image:http://www.sciencebob.com/graphics/youwillneed.gif width="233" height="75"]]
 * 1 inch (2.5 cm) wide PVC Pipe about 24 inches (60cm) long. You can also use a regular balloon if you do not have PVC pipe.
 * Mylar tinsel for Christmas trees. There are many types of tinsel - you should look for the thinnest and narrowest possible. The tinsel used in the video is about 1 millimeter wide. If it is much wider than that, the orb may be too heavy to levitate. ( see below to get tinsel from Bob )
 * A head of clean, dry hair
 * Scissors
 * 1.** Arrange 6 strands of mylar together and tie them together in a knot at one end.


 * 2.** Tie them together again about 6 inches (15cm) from the first knot.


 * 3.** Cut the loose mylar strands off just past each knot.


 * 4.** Charge the PVC pipe by rubbing it back and forth through your hair for 10 seconds.


 * 5.** Hold the mylar orb (by the knot) above the charged pipe and let it drop and touch the pipe.


 * 6.** It should repel away and start floating. If the tinsel keeps sticking to the pipe, the tinsel is probably not thin enough and you will need to try another kind of tinsel or order some from us. (You will usually have to "recharge" the pipe before each levitation.)



It is all about static charges. Similar static charges repel away from each other. When you rub the pipe in your hair you give the pipe a //negative// static charge. The orb is attracted to the pipe at first because the orb has a positive charge. As soon as the orb touches the pipe, it picks up a negative charge. Since the pipe is negative and the tinsel orb is now negative, they repel away from each other and the orb levitates! The orb will also take on more of a "ball" appearance when charged since all the tinsel strands are repelling away from each other. Did you notice the orb is attracted to other objects around you - including you? That is because most objects (including you) have a positive charge.

The project above is a **DEMONSTRATION**. To make it a true experiment, you can try to answer these questions: **1.** Does the number of mylar strands affect how well the orb levitates?

**2.** Do different materials (hair, fur, wool) build up better static charges?

**3.** How long does the static charge last / how can you make it last longer?

**4.** Do different widths of pipe affect the floating ability of the orb? ||
