Answer:
1. Unusual or non-standard units for length are as follows:
- Cups
- Cubes
- Sweets
- A pencil
- An arm
- A toothpick
- A shoe.
2. Thermometer (2 photo examples)- A thermometer is an instrument for measuring and indicating temperature, usually one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and is contracted into the tube with heating and cooling (the degree to which something is hot or cold). It has two important elements: a temperature sensor (where some change occurs with a change in temperature); and some ways of converting change to a numerical value (e.g. the visible scale marked on a mercury-in-glass thermometer or the digital readout on an infrared model). Thermometers are widely used in technology and industry to monitor processes, meteorology, medicine, and scientific research.
Protractor (example in the picture)- The protractor is an instrument for measuring angles, usually in the form of a flat semicircle marked by degrees along the curved edge. Some protractors are simple half-discs. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle.
Temperature (example in the picture)- Temperature is the level or intensity of heat present in a substance or object, especially as indicated by a scale to be compared and shown by a thermometer or detected by a contact. It is a physical volume that expresses hot and cold. It is the reflection of thermal energy, present in everything, which is the source of the occurence of heat, a flow of energy, when one body comes in contact with another that is colder or warmer. Temperature is measured with a thermometer.
Step-by-step explanation:
1. Non-standard units of measurement are units of measurement that are not commonly used.
