Matters, Atoms, and Mixtures & Solutions
Solid, liquid, and vapor.
What is inertia?
The ability to do work.
What is energy?
They attract and repel.
How do opposite poles of a magnet interact with each other?
Life science, earth science, and physical science.
What are the three branches of science?
Any change of matter to its size, shape, or state.
What is a physical change?
An objects speed AND direction.
What is velocity?
An object doing motion.
What is kinetic energy?
These are materials that allow charges to move through them easily.
What are electrical conductors?
This is the variable that is influenced by the independent variable. It is the results of your experiement.
What is a dependent variable?
This shows the number of protons an atom contains.
What is an atomic number?
Objects of greater mass require greater force in order to accelerate.
What is Newton's second law of motion?
This form of energy is stored in bonds of atoms and molecules and is released during reactions like burning fuel or digesting your food.
What is chemical energy?
This type of circuit only has one path for the current to travel.
What is a series circuit?
The liquid that does the dissolving in a mixture. This is usually water.
What is a solvent?
It allows us to walk without slipping and allows cars to stop when brakes are applied.
How does friction help in daily activities?
This device is used to capture sunlight and turn it into electricity.
What is a solar panel?
This is what the magnet exerts on certain materials, including other magnets.
What is a magnetic force?
These are the remains of ancient plants and animals that were buried and changed over millions of years.
What are fossil fuels?
This is one process of separating small and large solid particles. First, put the mixture of different sized solids into a container that has a screen material at the bottom. Then, move the container around so that the smaller particles go through the screen and the larger ones do not.
What is sifting?
This has a net force in one direction. For example, riding a bike with the wind at your back.
What is an unbalanced force?
The higher an object is off the ground, the more of this type of energy it has.
This is the point on Earth's surface where the planet's magnetic field points vertically downward.
Who is Dmitri Mendeleev?
