100
These two things attract each other.
What are positive and negative charges?
100
This is the unit for the rate of current.
What is ampere or amp?
100
This refers to the different ways scientists study the natural world.
What is scientific inquiry?
100
The invention of this made it possible for people to discover and learn about cells.
What is a microscope?
100
This helps to support and protect plant cells.
What is a cell wall?
200
This is a region around a charged object where the object's electric force is exerted on other charged objects
What is an electric field?
200
This is a complete, unbroken path through which electric charges can flow.
What is an electric circuit?
200
This is a possible answer to a scientific question.
What is a hypothesis?
200
This uses a beam of electrons instead of light to magnify an image.
What is an electron microscope?
200
Both animal and plant cells have these. It has been nicknamed the "gate keeper" of the cell.
What is the cell membrane?
300
This is the buildup of charges on an object.
What is static electricity?
300
This is a material through which charges can flow easily.
What is a conductor?
300
These are the facts, figures, and other evidence gathered through observations.
What is data?
300
He was one of the first people to observe cells.
Who is Robert Hooke?
300
This directs all of the cell's activities.
What is the nucleus?
400
There are 3 ways charges can be transferred to build up static electricity: friction, conduction, and this method.
What is induction?
400
This potential difference causes a current in an electric circuit.
What is voltage?
400
This is a statement that describes what scientists expect to happen every time under a particular set of conditions.
What is a scientific law?
400
Schleiden, Virchow, and this scientist were key in developing the cell theory.
Who is Schwann?
400
These are the "powerhouses" of the cell because they convert food to energy.
What are mitochondria?
500
Lightning is a dramatic example of this.
What is static discharge?
500
Long wires have more of this than short wires.
What is resistance?
500
This is a well-tested explanation for a wide range of observations or experimental results.
What is a scientific theory?
500
This is the ability to clearly distinguish the individual parts of an object.
What is resolution?
500
These capture energy from sunlight and use it to produce food for the cell.
What are chloroplasts?
