Scientific Investigation
Scientific Investigation
Name the researchers who challenged the prevailing belief that stress and diet were the primary causes of peptic ulcers.
MARSHALL AND WARREN
-State the technology and scientists whose work contributed to advancements in cancer treatment and ancestry discovery through radiation research.
Rosalin Franklin, Marie Curie and X-ray Diffraction
A scientific claim is considered strong when repeated experiments produce similar results.
reliability
This process ensures that scientific research follows ethical guidelines and prevents harmful experimentation.
scientific regulation
This principle states that correlation does not necessarily imply causation, preventing misleading conclusions in research.
causation vs. correlation
State the inventor responsible for developing the first microwave oven based on his observations of electromagnetic waves
Spencer
Identify the scientific breakthrough that helped refine particle physics and improve radiation therapy techniques.
Hadron Collider and Higgs Boson
This factor determines whether an experiment truly measures what it is intended to test.
validity
This major environmental disaster led to increased scepticism about nuclear energy and stricter safety regulations.
the Chernobyl disaster
This scientist's accidental discovery of penicillin in 1928 revolutionized medicine by leading to antibiotics.
Alexander Fleming
Who performed an early experiment on photosynthesis by tracking changes in soil and plant weight?
Von Helmonts
idenitfy an example of a native plant that Aboriginal people used for medicines or material
Alo vera, Maningrida Weavers, Tea tree leaves etc.
This type of error occurs when measurements are consistently off due to flaws in the equipment or method.
systematic error
Governments use this type of scientific research to create laws and policies that protect public health and the environment.
evidence-based policy
This theory states that all living organisms are made up of cells, which are the fundamental units of life.
the Cell Theory
Who developed a method involving the angle of the Sun’s rays and the distance between two cities to determine Earth's circumference?
Eratosthenes
The discovery of this fundamental force led to the development of nuclear power and radiation-based treatments.
radioactivity
This term describes a claim that appears scientific but lacks empirical support and rigorous testing.
pseudoscience
This principle ensures that scientific research follows moral guidelines and prevents unethical experimentation.
ethical regulation
This breakthrough allowed scientists to edit genetic material with precision, revolutionizing medical research.
CRISPR gene editing
Name the researcher who conducted experiments with a mouse, a candle, and a plant in a sealed jar.
Priestley
The discovery of this subatomic particle confirmed the Standard Model of physics and led to advancements in energy research.
the Higgs boson
This type of misleading argument relies on emotional appeal rather than scientific evidence, often seen in advertising
emotive reasoning
This innovation has transformed global communication, allowing instant access to information and scientific collaboration.
the internet
This innovation allows scientists to analyze DNA sequences, leading to breakthroughs in genetics and medicine.
DNA sequencing
