Rainbow Spectroscope #1

1. Cut the cardstock. Cut two squares of cardstock that are large enough to cover the ends of the cardboard tube with space left over. » If you do not have a cardboard tube, then use additional cardstock to make a tube!

2. Add the film.Use the hole punch to punch a hole in the center of one of the squares of cardstock. You might have to fold the edge of the square to get the hole punch over the center. » Now tape a small piece of spectroscopic film over the hole that you punched. Do not get any tape over the hole!

3. Attach the cardstock. Place the cardstock with the spectroscopic film over one end of the cardboard tube. » Cut the cardstock into a circular shape and then cut slits towards the center all the way around the cardstock. Be careful not to cut too far! Only cut up to the tube-- do not make any cuts where the cardstock stretches over the opening. » Fold down the flaps that you made and tape the cardstock to the tube by wrapping tape around the flaps.

4. Option A spectroscope. Attach the other piece of cardstock to the other end of the tube using the same process that you used in step 3. » Use the thumbtack to poke a pattern into the cardstock. Be creative with your pattern!

5. Option B spectroscope. Cut the remaining piece of cardstock in half and center the two pieces over the end of the cardboard tube. Leave a couple millimeters of space between the halves. » Before you tape the pieces down, look through the hole that you punched on the other end and turn the tube until the rainbows run parallel to the slit. » After it is calibrated, tape the pieces down using the same method from step 3.

6. Look for rainbows!Look through the hole that you punched to see some rainbows! Try looking at different types of light such as fluorescent, incandescent, candlelight, daylight. etc. Remember, do NOT look directly at the sun!

Rainbow Spectroscope #2

1. Prepare the template. In this tutorial, you will use the template on the next page to create your spectroscope. » Start by gluing the template to an opaque piece of paper (opaque means that you cannot see through it). » Next, cut the template out according to its instructions. You will need the craft knife to cut out the two windows.

2. Build the spectroscope.Follow the instructions on the template to construct the spectroscope. » After it is completed, cut two flaps on the bottom underneath the eye window and open them (see picture on the left).

3. Option A. Take your CD or DVD and tape it shiny-side-up to the bottom of your spectroscope. The shiny side of the CD should completely cover the opening that you cut in step 2. » Use the sides of the CD as handles and try out your new spectroscope! Look through the eye window directly down onto the CD while aiming the other window at a source of light. Do not aim it directly at the sun!

4. Option B. Put the safety goggles on and cut the CD or DVD into sixths. » Tape the piece of CD shiny-side-up over the opening that you cut in step 2. Make sure the opening is completely covered. » Test out your new spectroscope by looking down through the eye window at the CD while aiming the other window at a source of light. Do not aim it directly at the sun!
