 If a rock were taken from earth to the moon, how would its mass and weight be affected? Rock will weigh less because there is no gravity on the moon. The force of the gravity between your body and the moon would be less. List four properties of matter liquid, gas, solid and magnetism What is magnetic another property of? Matter What happens when an object is placed in water? If the upward push is strong enough compared to the object's weight, the object will float. How do you measure weight? Use a quantity called the newton to measure force. One newton is the same of .22 pounds How is volume measured? Cubic centimeters What happens if the density is more than the water's density? The matter will sink. What happens if the density is less than water's density? The material will float. What is buoyancy? The push up on an object What is density? How tightly packed matter is. What are three forms of matter? Gas, Liquid and solid What is actually the force of gravity between Earth and a book? Weight Measures how much space a sample of matter takes up VOLUME What does Conduct do? It allows heat or electricity to flow through readily What properties are used to classify matter? density, ability to conduct electricity and magnetism What metal is a good conductor of electricity? Copper What is Density? A measure of how tightly packed matter is; the amount of mass contained in a given volume What is volume The amountof space an object takes up What is weight? (on Earth) a measure of the force of gravity between Earth and an object What is Mass The amount of matter in an object Why is plastic used to coat the wire that conducts electricity? It insulates the passage of the electricity so the person holding the wire will not get shocked. What is buoyancy? The upward push on an object by the liquid (or gas) the object is placed in How many poles does a magnet have? 2 -North and South How do engineers and scientists use properties of matter? When they design and build things How is mass measured? Kilograms What does Insulate mean? It does not allow heat or electricity to flow through readily. What is magnetic? when certain object push or pull on each other. Anything that has mass and takes up space MATTER
