Fluorescent Fun

Please read the procedure before beginning! After reading, please watch the video. Some activities require more time and cleanup than others. You also have the choice of performing these activities in a way that suits your needs.

Not for children under 3 years. Adult supervision is required. Follow approved procedures.

Materials

· Container with lid

· Flour

· Salt

· Cream of Tartar

· Vitamin B capsule

· UV Flashlight

· Tongue Depressor

· Vegetable Oil

· Warm Water (not included)

· Highlighter

· Pliers

· Glow Dinosaur

· Glowstick

Procedure

1. Do this activity in a place where cleanup is easy. Ensure that the lights can be turned off with few windows—this activity works better in the dark!

2. Add the flour (approx. 1 cup), salt (approx. 1/3 cup), and cream of tartar (approx. 2 teaspoons) to the plastic container.

3. Carefully open the Vitamin B capsule by pulling apart the two halves, and pour the contents into the container. Turn off the lights, and shine the UV flashlight on it. What do you notice?

4. Stir the contents with the tongue depressor.

5. Use the pliers to remove the white piece from the bottom of the highlighter. Remove the ink sponge and squeeze it into 1/2 cup of warm water (not included). Turn off the lights, and shine the UV light onto the highlighter and ink. What do you notice?

6. Add the vegetable oil (approx. 2 tablespoons) to the dry ingredients in the plastic container.

7. Mix thoroughly while slowly adding the water. You have created glow dough! When the dough no longer sticks to your hands, stop adding water. Turn off the lights, and shine the UV light onto the dough! What can you make with your glow dough? Place the dough in the container and replace the lid to keep it from drying out.

8. Shine the UV light on the glow dinosaur and turn it off. What do you notice? Does this glow differently from the other materials?

9. Bend the glowstick until you hear clicking and watch what happens. Does this glow differently from the dinosaur?

Science Behind it!

Energy is anything that has the capacity to produce the change in matter. Matter is anything in the universe that has weight and takes up space. Cars move thanks to energy. We can walk because of the energy from the food that we eat. There are different types of energy such as chemical, nuclear, thermal, physical, sound, and  electrical. For this activity, we are exploring light energy.

You can physically see light. You cannot physically see energy but did you know that light is actually a form of energy. When the energy comes in the material, the material holds onto the energy and then releases it where is goes out. Something glows or you can see light because the energy is being released from the material as light energy, this is called photoluminescence. In this activity, you are exploring three types of luminescence: fluorescence, phosphorescence, and chemiluminescence.
