Why does the light bulb light when the needle touches a paper clip?
A circuit is complete
Does pencil fade on paper?
yes pencil fades on paper overtime especially pencil drawings this is due to the friction caused when paper rubs off against each other even when flipping pages and with moisture one day you will have a dark line drawn of pencil then later the line becomes lighter and lighter until you can easily erase them. On a science level i think its because the paper molecules are breaking down constantly
How can you write with a pencil?
A sharp point on a pencil will be eroded by a rough surface (paper) and leave a coating of graphite. This does not immediately penetrate the paper and can be erased. After some time, the paper will absorb some graphite molecules into its structure, and erasures will not be complete.
Would a paper clip complete a circuit to make a light glow?
yes because metal obsorbs electricy and makes a complete flow in a circle
Is a pencil technology?
Yes, it one part of writing technology (which includes paper, paper mills, pencil making machines, erasers, eraser making machines, etc.) which is a portion of communications technology.

Why colorful pencil?
Coloured pencils have pigment embedded in the wax. When the pencil is rubbed against the paper, the tiny imperfections in the paper hold the wax that has the color. The principle is the same with wax crayons, but the pencil has much harder wax. To test this, colour a piece of paper with the pencil, then hold the drawing to a light bulb. You will find that the colours will "melt" with the heat and get a bit brighter. The wax was absorbed into the paper leaving the colour in the paper bits.
What does paper and pencil relate to math?
You can do calculations using a pencil to write on paper!
Which is the least authentic mode of assessment?
Multiple choice tests are often considered the least authentic mode of assessment as they generally do not require deep critical thinking or creativity. They tend to focus on rote memorization and do not effectively assess a student's understanding or application of knowledge.
What is the outcome of adding a metal paper clip and then a rubber pencil eraser to a circuit?
A metal clip is a conductor. A rubber is not. If there is a complete circuit (of conducting materials), current will flow - if the circuit is interrupted at any point, for example with the rubber, it won't.
How do you draw a dove?
get a pencil and some paper and draw a dove with the pencil onto the paper
Why does a pencil leave a mark on paper?
When a pencil is rubbed on paper fiction causes a small amount of the graphite from the core of the pencil to be left on the paper. This leaves a visible mark.
Does a pencil or a paper clip have more mass?
A pencil has more mass than a paper clip no matter how big the pencil is.
Explain why using a metal paper clip to connect to the wire at B will light the light bulb?
The metal paper clip will conduct electricity, so completing the circuit.
Why Can you not see youself in a piece of paper?
Because unlike in a mirror, the light does not bounce off the paper, but it is absorbed. People use paper to write because the absorbed light contrasts with the graphite of the pencil, making it easy to adjust to, or read the literature.

Is mathematical genius connected to ability of huge mental calculations?
No, not at all. Many professional mathematicians are unable to do relatively simple arithmetic without pencil and paper.
