Scientific Method
This is the first step of the scientific method
Make an observation
Charge of an electron
Negative
This is a group of two or more atoms held together by chemical bonds
Molecule
This is an example of an element
Oxygen, hydrogen, carbon, etc.
Cheetahs can run up to ____ mph
60
This is a testable explanation for an observation
Hypothesis
This is the smallest unit of matter
Atom
This type of bond involves the sharing of electrons
Covalent
This is a substance made of only one type of atom
Element
This is the first and only sport played on the moon
Golf
This is a factor that is changed or manipulated in an experiment
Independent variable
This is the charge of a proton
Positive
This type of bond is formed when electrons are transferred from one atom to another
Atomic Number is determined by
Number of protons
Babies are born without this bone in their body
Knee caps
This factor acts as a baseline for comparison with experimental groups to allow researchers to isolate the effects of the independent variable
Control group
This is a charged atom
Ion
This rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell
Octet Rule
A water (H2O) molecule is held together by this type of bond
(Polar) covalent
This is the biggest animal on earth
Blue whale
These are all the steps to the scientific method
- Make observations
- Ask a question
- Research the topic
- Plan the experiment
- Conduct the experiment
- Record the data
- Analyze the data
- Make a conclusion
These are located in the nucleus of an atom
Protons & neutrons
This type of bond forms between a metal and a nonmetal
Ionic
Atoms of the same element with different numbers of neutrons
Isotope
This many people have walked on the moon
