The Process Of Science

Vocabulary

100

What is the difference between a line graph and a pie graph?

A line graph shows trends over time (how something changes), while a pie graph shows parts of a whole (how a total is divided).

200

What are the three important words for a hypothesis?

If-----Then----Because

300

If you increase the amount of sunlight a plant receives, then the plant will grow taller.

What are the independent and dependent variables?

• Independent Variable (IV): The amount of sunlight (the thing that changes).
• Dependent Variable (DV): The plant's height (what is measured; depends on the IV). 

400

Make this into a testable question.

How many students are in this class?

Does the number of students in a classroom affect the amount of one-on-one time each student receives from the teacher?

500

These are the factors in an experiment that a scientist deliberately keeps exactly the same across all groups to ensure a fair test.

What term is this?

Control

IV/DV

100

What are some ways you can tell what the independent variable is?

Independent variables are the only thing that should be changed in an experiment

200

What does a dependent variable do in an experiment?

Dependent variables respond to the change you make

300

Which variable changes the outcome?

Independant

400

As the amount of sunlight a plant receives increases, the speed of its growth also increases.

What are the independent and dependent variables?

• Independent Variable (Cause): Amount of sunlight (what you change/manipulate).
• Dependent Variable (Effect): Speed of growth (what you measure/what responds).

500

Will an egg float higher in water with more salt?

What are the independent and dependent variables?

Independent Variable: The amount of salt added

Dependent Variable: How high the egg is

Graph Types

100

Define a pie graph

Pie graphs are circular charts divided into slices, each slice represents a percentage of the whole

200

Define a line graph

Line graphs connect data points with lines to show how a variable changes (usually over time), and show patterns between two sets of values

300

Define a bar graph

Bar graphs are diagrams in which the height or length of lines or rectangles of equal width represents the numerical values of variables

400

What is the difference between a pie graph and a line graph?

Pie graphs represent proportions of a whole (percentages at a single point in time) using slices of a circle, while line graphs show trends and changes in data over a continuous period, plotted as points joined by lines.

500

What is the difference between a bar graph and a line graph?

Bar graphs compare distinct categories with bars, ideal for "which is bigger," while line graphs connect points to show trends over continuous data (like time)
