Why is science so reliable? By basing its conclusions on multiple lines of evidence drawn from experiments and observations, science seeks to build reliable knowledge and provide scientific explanations that people can use to better understand the world around them and inform their decision making. What is science PBS? If you look up the word […]
What happens if a chlorine atom attracts a sodium atom?
What happens if a chlorine atom attracts a sodium atom? A sodium atom loses an electron to a chlorine atom. The sodium atom becomes a positive sodium ion. The chlorine atom becomes a negative chloride ion. Both sodium ions and chloride ions have full electron shells. When a chlorine atom gains an electron what does […]

What are the 5 evidence of continental drift?
What are the 5 evidence of continental drift? The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. Why was Pangea not accepted? This idea was quickly rejected by the scientific community primarily because the actual forces generated […]
What is a fibrous joint example?
What is a fibrous joint example? Fibrous joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints called sutures. The skull bones of a fetus are unfused so that they can move over each other slightly to compress skull size during birth. Which joint do […]
What happens to energy and matter in ecosystems?
What happens to energy and matter in ecosystems? Any nonliving matter that living things need is called a nutrient. Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems. Decomposers release nutrients when they break down dead organisms. Do all living things obtain the matter and energy they need to live […]
Does tire pressure go up after driving?
Does tire pressure go up after driving? As temperature levels change, so does the air pressure in your tires. It’s the same as when you drive at higher speeds for an extended period: the tire warms, and the air within expands and increases pressure. Can you drive on a tire with 15 psi? It’s always […]
What is the best material for aircraft composite construction?

These are fiberglass, carbon fiber, and Kevlar. Glass fiber or fiberglass is the most widely used reinforcing material. Which are some of the disadvantages of using […]
What causes change in season?
What causes change in season? The Short Answer: Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the […]
How do you break the current in a circuit?
How do you break the current in a circuit? The most common way to measure current in a circuit is to break the circuit open and insert an “ammeter” in series (in-line) with the circuit so that all electrons flowing through the circuit also have to go through the meter. What happens when there is […]
