Matter & It's Properties
The energy of motion.
What is Gravitational Energy?
Daily Double: What object in our solar system would we consider to have the strongest gravitational pull?
What do you call two or more substances that are combined and do not change their physical properties?
What is a mixture.
A similarity between a controlled experiment and the engineering design process.
Examples: They both begin with a question or problem, involve gather in information or doing research, designing a prototype or test to gather data, running repeated trials, and sharing results with other scientists.
The energy produced by the motion of electrons between atoms.
What is electrical energy?
Daily Double: Name two materials that conduct electricity.
This is a combination of two substances that are uniformly or consistently mixed together, but do not change their physical properties.
What is a solution?
Daily Double: Give an example of a solution.
A force that works against motion.
What is friction.
Daily Double: Name one way we could increase friction between a wheel and a flat surface.
A tool that measures temperature.
What is a thermometer?
Mass, volume and density are used to identify matter. What type of properties are they?
What are Physical Properties.
This type of energy is demonstrated when an object of higher mass pulls smaller object towards it.
What is Gravitational Energy?
Daily Double: What object in our solar system would we consider to have the strongest gravitational pull?
Name two ways you can increase the speed at which one substance is dissolved into another substance.
What are increasing the temperature and stirring the mixture?
The definition of energy.
What is the ability to make a change or cause motion?
The amount of a substance that can be dissolved in another substance is a measure of its ____________.
What is solubility.
Daily Double: What is the point at which no more of a substance can be dissolved called?
When the forces in one direction are stronger, so they don’t cancel each other.
What is unbalanced forces.
This state of matter typically has the most matter compared to its volume (also known as the most density).
What is a solid?
Daily Double: How do you find the density of an object?
The process by which heat energy travels from a stovetop to a pot of water.
What is conduction?
Daily Double: Give an example of another type of energy which is conducted.
This is the substance that dissolves another substance in a solution.
What is a solvent?
Daily Double: Which is the substance which dissolves called?
Objects will stay in the same state, in motion or at rest, unless acted upon by another force. What is this property called?
What is inertia?
Daily Double: Why do most moving objects on Earth eventually come to a rest?
Repeated examples, prototypes, or trials are known as this.
What are iterations?
Daily Double: Why do we repeat trials of an experiment or design?
