- is a prefix that means “false”
- Pseudoscience is a “false science”.
- cannot support hypotheses BASED ON DATA.
- cannot draw valid conclusions BASED ON DATA.
- Some fetal gender predictors
Scientists must be:
Science & Math
- Science can be described and analyzed mathematically.
- Math allows scientists to compare measurable data.
- What is matter composed of?
- How do molecules combine to form materials around us?
- To understanding living things, you must understand chemistry.
- You must understand physics to understand chemistry.
Science GONE BAD
- Many other Past Medical Treatments
SCIENCE & TECHNOLOGY
- What technology do we use everyday?
- What do we use technology for in Science?
- Why do we have technology?
Good or Bad?
- What are our general feelings about technology?
- What are the disadvantages?
- What risks are there in scientific improvements?
- When do the benefits outweigh the risk?
- Who decides now? Who should decide?
What is a THEORY?
- Group of verified hypotheses about certain aspects of the natural world.
- Theories may change as scientists learn more about the topic.
- The Theory of the Big Bang
- The Theory of Plate Tectonics
What is a LAW?
- Scientific Law or Principle:
- Something that has been tested over and over again and has not been contradicted.
Fact & Speculation
- Scientists rarely say that information is factual.
- a generally close agreement among competent observers studying the same thing.
- A fact can be “disproved” if experimental data shows otherwise.
- Speculation - a statement that cannot be tested to be correct and/ or incorrect.
- Can you make a speculation?
- “ Intelligent life exists on another planet somewhere else in the universe”
- You cannot test everything. Sometimes you just have to take someone’s word for something.
- What information is “acceptable”?
Criteria for determining if information is “acceptable”
- Comes from a RELIABLE source.
- Is NOT funded or conducted by a stakeholder.
What QUESTIONS will we answer this year?
