Unit 1: Scientific Knowledge and Practices
This is something that can change, or vary, in an experiment.
What is a variable?
This theory states that all matter is made up of tiny particles called atoms.
What is the atomic theory?
This is an important part of a circuit. The circuit will only work if this is closed.
What is a switch?
A push or pull.
What is force?
This planet has the longest revolution around the sun.
What is Neptune?
This graph shows fractions or percentages of a whole.
What is a circle graph/pie chart?
This particle has a negative charge, and is the smallest particle in an atom.
What is an electron?
This type of circuit has only one path for the electrons to travel. If one load is broken, the whole circuit is broken.
What is a series circuit?
This is where an object is located.
What is position?
The Milky Way Galaxy is this type of galaxy.
What is a spiral galaxy?
This is a chart used to organize data in rows and columns.
What is a data table?
A solution is always this, but this is not always a solution.
What is a mixture?
Many objects can transform energy into this, including a computer, a human, and an old neon light.
What is sound energy?
Gravity can change how fast an object moves, which is called this.
What is speed?
This is the distance that light travels in one year, in kilometers.
What is a 9.5 trillion kilometers?
This is a series of steps that scientists use as a guide to answer a question or solve a problem.
What is the scientific method?
A physical change from gas to liquid.
What is condensation?
This type of energy is commonly created as waste. Electrical energy accidentally transforms into this, which loses some energy that was meant to be transformed into other types.
What is thermal energy?
This is movement, or a change in an object’s position.
What is motion?
A comet’s tail always points in this direction.
What is away from the sun?
The final step of the scientific method.
What is to share your conclusion?
This is a method of separating matter in which substances of different densities separate themselves because less dense objects float on top of more dense objects.
What is floatation?
This is a type of energy made by the sun.
What is solar energy?
An example of this is a game of tug a war where there is one person on one side and five people on the other side.
What is an unbalanced force?
These are pieces of rock or dust in space that come from asteroids or comets.
What is a meteoroid?
