Scientific MethodSlide3

1. Problem

This is a question that the experiment is asking

Example: Why does my breath smell in the morning? Slide4

Observation/Research

Make observations and do research

Examples:Research about teeth, bacteria, and oral hygieneSlide5

Hypothesis

Needs to be in a IF

THEN statementExample: IF a person brushes and flosses their teeth twice a day, THEN their breath will not smell. Slide6

Hypothesis

IF

a person brushes and flosses their teeth twice a day (what you’re changing in the experiment), THEN their breath will not smell (what you think will be affected). Slide7

EXPERIMENT

It has 2

groups : the control group and the experimental group. The control group remains the same The experimental group has one variable changedSlide8

Control

Students will brush their teeth “normally,” twice a day

Remains the sameExperimental

Students will brush and floss their teeth twice a day

We’ve changed one variableSlide9

Independent Variable

The variable that

YOU CHANGE is called the independent variableThe experimental group receives the independent variableSlide10

Dependent Variable

The dependent variable is what’s

affected by the independent variableSlide11

What is the independent variable in our experiment?

IF a person

brushes and flosses their teeth twice a day, THEN their breath will not smell. Slide12

What is the dependent variable in our experiment?

IF a person brushes and flosses their teeth twice a day, THEN

their breath will not smell. Slide13

5

. Collect and Analyze data

6. Make a Conclusion7. Report the Results8. Repeat the experimentAfter the experiment you will…..Slide14

What will always make an experiment better

Having

a larger sample size (ex: more people)Repeating the experimentHaving an equal number of males to femalesIncreasing the number of trials
