Helpful questions . . .
If you had to pick a documentary on Netflix what category would it fall under?
What do you enjoy doing in your free time?
What grabs your attention/what do you find interesting?
What have you enjoyed studying in science?Slide9
What science topics do you find interesting?
Think general and big picture
For example:
Psychology- how people think/why we think the way we do
Chemistry- how materials interact/what things are made of
Physics- mechanics of how things work
Biology- the study of life/how living things work
Geology- the study of the Earth/organic material Slide10
Example
I LOVE watching documentaries on food
I enjoy trying new foods/restaurants/cooking
Biology/chemistry/cultures and different foods interest me
What should I research?
FOOD SCIENCE Slide11
Why should we care about answering your question?
Does your question lead to more questions?
How could it help the real world?
Why should you spend a month researching this topic?
CONVINCE me this is important!Slide12
My Example
On average a family of 4 spends $1500 on wasted food each year.
Roughly ⅓ of the food produced in the world (1.3 billion tons) is wasted each year.
On average 21,000 people die everyday due to hunger or hunger related causes. Slide13
Procedure
Needs to include controls and variables
Needs to be so specific that someone who knows nothing about science could run your experiment and get the same results Slide14
Testable questions have two variables. . .
Independent
Dependent Slide15
Variables
Independent Variable:
What the scientist is changing in the experiment Slide16
Variables
Dependent Variable
What the scientist is measuring in the experiment Slide17
Variables
Controls
All of the things that are kept the same in an experiment so that we can accurately conclude what is causing the change Slide18
