Do as lot of research. Check out some light drawing that this old guy named Picasso used to make.Do a google image search for drawing or painting with light. After you see what is possible:

1. The first thing you need to do is find out how you can get your camera to keep the shutter open as long as it can. Ideally 5 to 30 second exposures are good. See if your camera has an adjustable shutter. See if it has a fireworks mode.Try experimenting in the dark with every mode.

2. Choose a light source.Some ideas: cell phones. glow sticks, flash lights, anything that will light up. Experimentation is your friend.

3. Decide if you want to hand hold, or place your camera on some object while the sensor is being exposed. Experiment with both to see which method you like best.

4. Find a dark room or go outside at night and experiment.

Your assignment will be graded using these criteria:

From Mr. P's Photo Rubric

Vision:
Is you image original, innovative and daring, or just another example of the same old thing? Does it fulfill the requirements for the assignment (see assignment requirements above) ?

Aesthetics:
Have you used the appropriate elements and principles of design that would enhance your photograph or did you just shoot what was in front of the camera? Have you used good composition or did you just place the center of interest in the center because it was easy?

Mechanics:
Camera Techniques: Is the image sharp/in focus? Is the exposure correct? Was the appropriate aperture/shutter speed used (if applicable for your camera), did you find the best angle?

Computer Techniques: Is the image sharp/in focus? Is it resized correctly? Is it color corrected and sharpened?

Presentation: Is the artwork presented in a professional manner as outlined in the assignment?

Good luck
