Weigh three random marbles against three random marbles. (Thats weighing number 1.) If they balance, take three away and check the last three. (That's weighing number two.) The scale will not be in balance. Pick one from the new group and weigh it against another one of the new group. (That's weighing number 3.) If they balance, the unweighed marble is the heavy one. If they don't balance, the lower marble is the heavier one.
Now that I've got your interest piqued, solve this one... You have 12 marbles, one is either lighter or heavier than the others. What is the minimum number of weighings required to indentify the odd marble?
Pick 6 marbles. Weigh 3 against 3. If they balance, then weigh the other two against each other to find the heavier one. If they don't balance, look at the three that are heavier. Pick 2 and weigh them against each other. If they balance, then the 3rd marble in that group is the heavier one. If they don't balance, you have the heavier one.
Weighing 1: Weigh any four against any other four. The set containing the heavier marble will be heavier. Weighing 2: Weigh any two from this heavier set against the other two from the set. The pair containing the heavier marble will be heavier. Weighing 3: Weight the two marbles from the heavier pair against one another and you have the odd marble. Simple!
No, marble is a rock, however it is acidic slightly.
2 pounds
it is a heavy, solid rock with charcaterisitc white colouring
A graduated cylinder or a beaker with volume markings would be appropriate for measuring the volume of a marble. Simply add water to the cylinder or beaker, record the initial volume, then carefully drop the marble in and record the new volume to calculate the volume of the marble.

Walking on a wet marble floor can be difficult because the smooth surface of marble does not provide much traction when wet, leading to a higher risk of slipping and falling. Additionally, water on the surface of the marble can create a slippery layer that makes it hard to maintain balance while walking.
A marble's cleavage refers to how the marble breaks or fractures along certain planes. Marble has a tendency to break along flat planes due to its crystalline structure, creating smooth surfaces when separated. Cleavage is used by geologists to help identify and classify different types of rocks and minerals.
Limestone and marble are primarily composed of calcite, a mineral that reacts with acid by producing bubbles. This reaction is commonly used to identify these rocks in the field.
The format of the Taj Mahal shows symmetrical balance, with its iconic white marble shape mirroring perfectly alongside its central axis.
No. A marble is made of glass, not marble. Glass will not react with vinegar. Edit - Some antique marbles ARE crafted out of marble or other stone/ rock types. Using ANY sort of chemical to clean them can possibly damage the surface finish or even worse, cause the marble to break or split. I happen to own a few antique marbles from the 1880's to the early 1900's. To clean them use a damp, warm soft cloth. Try checking each marble by carefully rubbing a small portion of a marble before cleaning the entire marble(some marbles are sun hardened clay, and getting one wet can damage them). One other method to identify the material your marble(s) are made out of - try a local rock shop. Most rock shop owners can identify what your marble is made from, if it is a naturally occurring rock. They might even be able to provide the possible value of your marble(s), but you should ALWAYS get a second opinion for any value appraisals.
