1. The U.S. customary system of measurement is a system of measurement used in the United States. It includes units such as inches, feet, pounds, and gallons.

2. A meter is a unit of length in the metric system. It is equal to 100 centimeters or approximately 39.37 inches. It is commonly used to measure distances and lengths.

3. The metric system and the English system (U.S. customary system) are two different systems of measurement. The metric system is a decimal-based system used by most countries around the world, including scientists. It uses units such as meters, grams, and liters. The English system, on the other hand, is used in the United States and includes units such as inches, pounds, and gallons. One major difference is that the metric system is based on powers of 10, making conversions between units easier.

4. A meter is a unit of length in the metric system. Some examples of objects that are approximately a meter in length include a baseball bat and a standard door.

5. Large or small distances can be measured in various ways. Some common methods include using a ruler or tape measure for shorter distances, a measuring wheel for longer distances, or even using GPS technology for very large distances.

6. Temperature is a measure of how hot or cold something is. There are three temperature scales commonly used: Celsius (°C), Fahrenheit (°F), and Kelvin (K). Celsius is commonly used in most countries, Fahrenheit is used in the United States, and Kelvin is used in scientific applications.

7. Mass is a measure of the amount of matter in an object. It is different from weight, which is the force of gravity acting on an object's mass.

8. Matter can be measured using various instruments and techniques depending on its properties. For example, the mass of a solid object can be measured using a balance or a scale, while the mass of a liquid can be measured using a graduated cylinder.

9. Derived units are units that are derived from basic units through mathematical combinations. One example not covered in the lesson is velocity, which is derived by dividing the distance traveled by the time taken.

10. The mass of an object is not affected by its location in space. The mass of an object remains the same regardless of whether it is on Earth, the moon, or in outer space.

11. Gravity is a force that attracts objects towards each other. It is responsible for the weight of an object. Weight is the force exerted by gravity on an object's mass.

12. Weight is affected by the location because the strength of gravity varies depending on the location. For example, an object will weigh less on the moon compared to Earth due to the moon's weaker gravitational pull.

13. The important thing to remember about the relationship between mass and weight is that mass is a measure of the amount of matter in an object and remains constant, while weight is a measure of the force of gravity on an object and can vary depending on the strength of gravity.
