3-D: Short for three dimensions. This term is an adjective of something with characteristics that can be described in three dimensions – height, width, and length.
astronaut: Someone trained to travel into space for research and exploration.
umbrella: The smallest structural and functional unit of the organism. Usually too small to be seen with the naked eye, it is composed of a liquid liquid surrounded by a membrane or wall. Depending on their size, animals are made up of thousands to trillions of cells. Most organisms, such as yeasts, molds, bacteria, and some algae, consist only of one cell.
chitin: A chewy, semi-transparent substance that is a major component of the arthropod̵7;s outer skeleton (such as an insect). Another type of carbohydrate, chitin is also found in the cell walls of certain fungi and algae.
mixture: Materials are created using two or more different building blocks, together they create something with new and better features. Carbon fiber reinforced polymers are one example. Immersed in these firm, hard plastics are filaments made of carbon. Engineers use these plastics to build lightweight bodies for racing cars and planes, among other things.
Compounds: (often used as a synonym for chemistry) A compound is a substance formed when two or more chemical elements are bound (bound) in fixed proportions. For example, water is a compound made up of two hydrogen atoms linked to one oxygen atom. Its chemical symbol is H2UMBRELLA.
concrete: Sure and real. (in construction) A simple building material, consists of two parts. Part is made of sand or reefs. The other is made of cement, which hardens and helps to bond the material particles together.
density: A measure of the concentration of a number of objects, found by dividing its mass by its volume.
Skill: The field of study uses math and science to solve real world problems.
habitat: An area or natural environment where animals or plants normally live, such as deserts, reefs, or freshwater lakes. A habitat can be home to thousands of different species.
insect: An adult type of arthropod will have six legs and three body parts: head, chest and abdomen. There are hundreds of thousands of insect species, including bees, beetles, flies and moths.
Mars: The fourth planet is from the sun, only one planet from Earth. Like Earth, it has seasons and humidity. But its diameter is only half the size of the Earth.
materials scientist: A researcher studies how the atomic and molecular structure of a material is related to its overall properties. Materials scientists can design new materials or analyze existing ones. Their analysis of a material’s overall properties (such as density, strength and melting point) can help engineers and other researchers choose the most suitable material for an application. new application.
metal: Something that conducts electricity well, tends to be shiny (reflective) and malleable (meaning it can be reshaped with heat and not too much force or pressure).
paradigm: A simulation of a real world event (often using a computer) was developed to predict one or more possible outcomes. Either an individual is used to show how something will work in or look like others.
ratio: Relationship between two numbers or quantities. When written down, numbers are usually separated by colons, such as 50:50. That means that for every 50 units of one thing (the left side) there will also be 50 units of something else (indicated by the number to the right).
red planet: A nickname for Mars.
regolith: Thick soil layer and weathered rock
Resistance: (in physics) Something that keeps a material material (such as a block of wood, stream of water or air) moving freely, usually because it creates friction to hinder its movement.
seashell: The hard, protective outer shell of mollusks or crustaceans (such as clams or crabs), bird eggs or some other relatively soft tissue needs to be protected (such as tree nuts or peanuts). (in ammunition) Explosive bullets, bombs, grenades or other ammunition.
Singapore: An island nation just off the coast of Malaysia in Southeast Asia. Formerly a British colony, it became an independent country in 1965. It is about 55 islands (the largest is Singapore) comprising some 687 square kilometers (265 square miles) of land, and is inhabited. accommodation for more than 5.3 million people.
emphasize: (in physics) Pressure or tension exerted on an object.
Technology: The application of scientific knowledge for practical purposes, especially in industry – or equipment, processes and systems as a result of those efforts.
three-dimensional printing (3-D): Computer program creation of a three-dimensional object follows instructions from the computer program. The computer tells the printer where to place consecutive layers of some raw materials, be it plastic, metal, food, or even living cells. 3-D printing is also known as additive manufacturing.
waste: Any leftover materials from biological or other systems have no value, so they can be disposed of as trash or recycled for new use.
