five senses
What does hypothesis mean?
This is a proposed explanation for a phenomenon that can be tested.
Pie Charts represent data as what?
part of a whole, out of 100%, or fraction
How many types of variables are there?

The first part of the scientific method after you make an observation and inference is
Ask a question
What do we use to make quantitative observations?
Numbers and measurements
The field of science that studies energy and motion
Physics
What are the three main types of graphs that we discussed in class.
Bar, Line and Pie
Define independent variable.
The variable that we change or test as scientists
Scientists use their five senses and numbers/ measurements during this time.
Observing
Make a qualitative observation about my room.
The field of science that studies matter and its interactions
Chemistry
Which variable always goes on the x-axis?
The independent variable
Define controlled variable
The variables that we keep the same.
When a scientist analyzes their data and expresses it visually they create
Graphs
Make a quantitative observation about my room
varied answers
Types of questions that cannot be answered by science
What does every graph need?
Title and axis labels
Define dependent variable
The variable that we are measuring
This part of the scientific method uses an " If then statement".
hypothesis
Length, temperature, volume, weight are all examples of...
quantitative observations

Bias
Line graphs are used to show what?
change over time
or relationship between
If we are going to test how the amount of sunlight affects plant growth and measure their height. Identify the independent or dependent variables and label them.
DV- Plant height.
After you have created your hypothesis the next step in the scientific method is to
