Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific classification?Terrestrial material synthesized to mimic lunar regolith
2. What is the key mimicked properties?Chemical composition, mineralogy, particle size distribution, mechanical strength, and engineering behavior
3. What is a lunar regolith simulant and why do scientists make it?It is fake moon dirt made from Earth materials that looks and behaves like real moon dust. Scientists use it to test tools, spacesuits, and machines before sending them to the Moon.
4. How do scientists make the simulant so it feels like real moon dust?They mix minerals, adjust particle size, shape, and density, and add tiny electrical charges so the dust sticks the same way as on the Moon.

Lunar Regolith: The unconsolidated layer of dust, soil, and broken rock covering the Moon's surface, formed by meteorite impacts.
Simulant: A laboratory-created substance designed to replicate the physical and chemical properties of a naturally occurring material.
In-Situ Resource Utilization (ISRU): The practice of using local resources available on a celestial body to support human exploration and settlement.
Mineralogy: The scientific study of minerals, including their chemical composition, crystal structure, and physical properties.
