Scientific Method
What is the first step of the scientific method?
What is making observations?
True or False: Science only affects people who become scientists.
What is false?
What are the three subatomic particles found in an atom?
What are protons, neutrons, and electrons?
A testable prediction based on observations is called a what?
What is a hypothesis?
What is one example of how biology helps improve human health?
Example: developing vaccines or understanding diseases.
What part of the atom contains protons and neutrons?
What is the nucleus?
What is the difference between the independent and dependent variable in an experiment?
The independent variable is what you change; the dependent variable is what you measure.
Why should scientists share their findings with the public?
To increase knowledge, inform decisions, and allow others to build on their work.
What is a compound?
Two or more atoms chemically bonded together.
Why is it important to have a control group in an experiment?
To have a comparison and see the effect of the independent variable.
Name one way science can be influenced by society.
Example: funding decisions, ethical concerns, public interest.
What is the main difference between ionic and covalent bonds?
Ionic bonds transfer electrons; covalent bonds share electrons.
Identify the independent and dependent variables: A scientist tests how the amount of sunlight affects plant growth.
Independent: amount of sunlight; Dependent: plant growth.
Explain how bias can affect scientific research and give an example.
Bias can lead to misleading results; for example, if a scientist only publishes results that support their personal beliefs.
Describe how a water molecule forms using covalent bonding.
Each hydrogen shares one electron with oxygen, forming two covalent bonds.
