Phenomena
& Bias
& Bias
What is a phenomena?
observable and measurable facts, events, or occurrences that happen in the natural world.
What are the three types of variables?
Independent Variable, Dependent Variable, and Controlled Variables
What are the two types of evidence you can collect?
Observational Evidence & Evidence with Numbers
What does scientific ethics mean?
it is a set of rules or principles that scientists follow when they are doing experiments or investigations
What are some examples of phenomenas?
Answers may vary
What is an Independent Variable?
It is the one thing that we choose to change to see how it affects everything else
Numerical Evidence
What are the 4 ways that scientists can be ethical when conducting experiments or research?
1. No changing data
2. Avoiding Harm
3. Respecting Privacy
4. Limit Bias
What is a Dependent Variable?
This is what we measure. It's the thing we watch or measure to see if the change we made (independent variable) had any impact.
For an experiment as a class we wanted to see what would happen if we mixed baking soda and vinegar into a zip lock bag. What type of evidence would be created in this experiments?
Observational Evidence
One way you have be ethical is by "Not Changing Data", what does this means?
Scientist record and report the data they collect truthfully, without altering it to fit a particular results. It ensures honesty and accuracy in scientific findings
What is bias?
Bias is like having a favorite or thinking something is better even before you check it out. It's our personal thoughts, feelings, or expectations that can sneak into our experiments without us realizing.
What is a Controlled Variable?
This is what we keep the same through the experiment. We keep them the same to make sure that any changes we see are because of the independent variable and not something else.
What is an example of Numerical Evidence and Observational Evidence?

One way you have be ethical is by "Respecting Privacy", what does this means?
When people take part in scientific studies, their privacy should be protected. This includes keeping their personal information confidential and ensuring that their participation is voluntary and informed.
In class we did an experiment where the teacher showed bias. What was the experiment and how was bias showed?
Answers will vary
From our experiment about variables where we tested what type of sport equipment was fastest down the hill tell me a: independent variable, controlled variable and dependent variable.
Independent Variables: type of equipment
Dependent Variable: speed of the equipment
Controlled Variable: incline of the hill and starting line
Numerical Evidence and Observational Evidence can also be called?
Quantitative Evidence and Qualitative Evidence
Two way you have be ethical is by "Limit Bias" and "Avoiding Harm", what do these means?
Limit Bias - it's crucial to minimize bias, so the results are objective and not swayed by individual perspectives.
Avoiding Harm - Scientists should conduct their research in a way that avoids causing harm to the environment, people, or animals involved in the study. This reflects a responsibility to prioritize the well-being of living things.
