100

The first two steps of the scientific method 

What are observation and question? 

100

What is the purpose of a control group in an experiment?

What is to provide a baseline?

100

Name the two different types of variables?

what are independent and dependent variables?

100

Come up with a hypothesis for an experiment on if classical music affects the rate of plant growth

If classical music is played, then the plants will grow faster 

200

In which step are you investigating your hypothesis?

What is an Experiment/ experimentation? 

200

What is the difference between independent and dependent variables?

What is a dependent variable changes due to the independent variable and the independent variable remains unaffected by the dependent variable

200

In experiment about the growth of a plant in different light amounts, what is the independent variable?

what is the amount of sunlight

200

What is the control group and experimental group for the music experiment?

What is the plants growing without music and the plants growing while music is playing

300
A statement that follows the format "If... then..."

What is a hypothesis?

300

Explain the importance of replication in an experiment

What is reliability of data and validity of the results. 

300

In an experiment on the reaction time of a driver to a road block, what is the dependent variable?

What is the reaction time of the driver?

300

What are the independent and dependent variables in this experiment?

Independent: the presence or absence of music 

dependent: the height of the plants/ rate of growth

400

In which step are students diving deep into the results of their experiment?

What is analyzing data and drawing conclusions?

400

How do you make an experiment more valid?

what is by increasing the number of replicates and number of participants

400

In a chemistry experiment, the students are testing the amount of oxygen released from a reaction where solute is added, what is the independent variable?

what is the amount of solute?
400

Name two controls that can be implemented to ensure the results are valid

There can be multiple: see what students say 

500

what is the difference between an inference and observation? 

An inference is when you conclude something from evidence and an observation is recording data

500

one way that a theory is different from an inference

what is that theories require A LOT of evidence 

500

Why is it important to control variables in an experiment?

what is to test only one relationship

500

What are two ways the experiment can become more valid? 

what is by increasing the number of replicates and number of plants
