1 Good Science vs. Bad Science H. Smith

2

3 Terminology Hypothesis: statement which predicts what will happen – Ex: If I drop this beaker, then it will break. Theory/Fact: generally accepted fact due to much, repeated evidence***still open to scientific inquiry b/c it’s not an absolute truth. – Ex: Gravity exists Opinions: non-measurable and impossible to prove, cannot be addressed by science – Ex: Pizza Hut has the best pizza in the world.

4 Characteristics of Good Science: Good Science: – Follows the scientific method (at least loosely) Observation Research Experimentation Results Analysis Conclusion PUBLISH!!!

5 Characteristics of Good Science: Good Science: – Does not investigate opinions, must have disprovable hypothesis – Ethical reports & procedures – Methods must be replicated many times with same result (you can’t make up data!) – Has many scientists working on similar projects, to validate data – Peer reviewed BEFORE publication – Publication in a peer reviewed journal=legitimate – Changes with new facts

6 Can Science Investigate? Are tomatoes or carrots more delicious?

7 Can Science Investigate? At what age do chickens start laying eggs?

8 Can Science Investigate? Does Vitamin C shorten the time a cold affects a person?

9 Can Science Investigate? Is it morally wrong to kill someone?

10 Can Science Investigate? Is cell phone use correlated with cancer?

11 Examples of Bad Science Ex 1: MMR Vaccine Health Scare – 1998 Dr. Andrew Wakefield – Published in the Lancet – Claimed MMR vaccine caused autism – Highly publicized by former model Jenny McCarthy – Discrediting began in 1999 – Formally discredited in 2010; lost medical license – Wakefield “fixed” information, only 12 children.

12 Why everyone has to vaccinate Herd immunity True/False? If you are immunized you cannot get that disease?

13 Examples of Bad Science: Multi-vitamin use: based on 1 math mistake Essentially no health benefits from taking a multi- vitamin Expensive urine Actually useful vitamin supplements: Folic acid, Vitamin D & Vitamin B12 Not proven to improve health, may be harmful Use the money to buy healthy food!
