Scientists
This scientist discovered the concept that all matter was made up of tiny indivisible shapes.
Democritus
What is at the core of an atom?
Nucleus
Which sub-atomic particle has a positive charge
Proton
Which is the variable that is manipulated?
Independent variable
First step of the Scientific Method?
Observation, Identify a problem, ask a question
This scientist came up with the billiard ball model of the atom. That atoms where tiny indestructible spheres.
What is in the nucleus?
Protons and Neutrons
Which sub-atomic particle has a neutral charge?
Neutron
Which variable is measured?
Dependent variable
The second step of the Scientific method?
This scientist discovered the electrons and devised the pudding model of the atom.
J. J. Thomson
Which subatomic particle moves around the nucleus?
The electron
Which sub-atomic particle has a negative charge?
Electron
Which variable remains the same in both the experimental and control group?
Constant variable
The third step of the Scientific method?
Test your Hypothesis - Experiment
This scientist discovered the proton and his model of the atom had a positive core with electrons on the outer edge of the atom.
Ernest Rutherford
Electrons can be found on energy levels called?
The electron cloud
What's inside the nucleus?
Protons and Neutrons.
This group in an experiment features the independent variable.
Experimental group
The fourth step of the Scientific method?
Collect and Analyze your data from your experiment
This scientist devised the planetary model of the atom, where the electrons circle the nucleus.
Neils Bohr
99.9 percent of the atom is made up of ?
Empty space
An atom of any element has what type of charge?
Neutral as each atom has a balance of protons and electrons.
This group does not feature the independent variable. It is used to measure against the group with the independent variable.
Control group
The last step of the Scientific method?
Come to a Conclusion.
