Types of Observations
What do we use to make qualitative observations?
five senses
What does hypothesis mean?
Prediction to testable question
Pie Charts represent data as what?
part of a whole, out of 100%, or fraction
How many types of variables are there?
3
The first part of the scientific method after you make an observation is
Ask a question
What do we use to make quantitative observations?
Numbers and measurements
What does it mean to interpret something?
To explain what something means.
What are the three 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.
What does it mean to research your topic?
To look up information about what you are testing and learn what is already known about the topic.
The Y axis goes (left or right) or (up and down).
The X axis goes (left or right) or (up and down).
y= up and down
x = left and right
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
What is the difference between qualitative and quantitative?
qualitative uses the senses
quantitative uses numbers and measurements
What three things 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
What is a controlled experiment?
An experiment in which we change one variable at at time.
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
