Scientific Method Lesson

​STEPS TO SCIENTIFIC METHOD

​All experiments begin with a QUESTION

A good QUESTION includes both the independent and dependent variables

Independent Variable: condition or factor that is intentionally changed by the Scientist

Dependent Variable: condition or factor that is observed and measured. It is caused to change by the IV.

Multiple Choice

What must a good question include?

• controlled variable

• control group

• independent variaable

• independent and dependent variables

​HYPOTHESIS

• ​Predicted Outcome to the experiment

• must include both independent and dependent variables

• written in "if... then" format

• If the (IV) is changed this way, then the (DV) will be changed this way

Multiple Choice

What is a hypothesis?

• educated gues

• predicted outcome

• variables which are kept the same

• group to which no treatment has been given

Multiple Choice

What format is best for a hypothesis?

• APA

• educated guess

• If...Then

  Format

• reverse format

​MATERIALS

• ​List of materials necessary for completion of the experiment

• must fully describe: size, quantity, type

Multiple Select

Which of the following are good example of procedure?

• in the garage

• recipe on back of Duncan Hines Cake mix

• on back of bag of potatoe chips

• instructions on bag of oatmeal

Multiple Choice

Which is not included in DATA?

• 5 oz of tap water

• pie graph

• line graph

• bar graph

Multiple Choice

Which is the best list of materials for reliable experimentation?

• some salt, some water, bowl

• pinch of salt, hot water, small cup

• 10g pink Himalayan salt, 1/4 cup of tap water, small bowl

• a little salt, some water, any bowl

​CONCLUSION

• ​Restate the hypothesis

• Does the data support my hypothesis or not? no right or wrong statements

• use specific data to substantiate findings

• what is the relationship between the independent and dependent variables

Multiple Select

What all is included in the Conclusion?

• relationship between IV and DV

• restatement of hypothesis

• possible reasons for error

• statement declaring whether data supports the hypothesis or not

• Warnings

• Possible Reasons For Error

• surveys used to gather information
