Next, have students place the bones in a jar of vinegar acetic acid for a day. A black light you can find them at places like Walmart and hardware stores, as well as online stores like Amazon.
Find a dark room. Please log in or create a free account to let us know how things went. From your results, do you think the glow-in-the-dark objects will glow longer in summer or winter? Set up your measuring device in a room with as few disturbances in lighting as possible.
Charge the object by exposing it to light for a specific time and then put it in the jar and monitor the resistance over time. Bend the leads of the photoresistor sideways and cover them in electrical tape, so they do not bump into each other and create a short circuit.
You can even make glow in the dark writing that is invisible in the day. Bad Question Can I use a different part?
We used kosher salt, but any salt will do. Does adding the second half of the tablet cause any changes? If you are using a highlighter, you will need the blacklight to make the mixture fluoresce. Next, open the jar and replace the cold water with hot water to increase the temperature, as follows: Electrical and electronics engineers may specialize in one of the millions of products that make or use electricity, like cell phones, electric motors, microwaves, medical instruments, airline navigation system, or handheld games.
Your resistance curve should start with a low level at first and then gradually rise to a higher level as the light intensity decays. This is to be done in a room that is available to be undisturbed for the duration of the experiment. Besides changing the brightness of the glow sticks, does the temperature also change how long the glow sticks glow?
In the dark, the resistance should be in the mega-ohm range. Were their predictions correct? What will the salt do to the ice? Thanks for the cool hub.
Make sure to let the leads of the photoresistor stick out from under the tape, so you can attach alligator clips to them later.
