False - there is not a single way to do science.

True - If you have to follow the scientific method

False - you can do science any way you'd like

Multiple Choice

The independent variable is the ONE thing you _____ in an experiment.

• test or change

• control or keep constant

• measure

Multiple Choice

Why do we want to test ONE INDEPENDENT variable at a time?

• Because the data table is harder to set up if you have more

• To know what is causing the changes. This helps us understand cause and effect.

• That is how things have always been done

Multiple Choice

The variable that is being measured or observed is called the _______________. Hint: this is the variable that is the result or effect

• independent variable

• dependent variable

• control variable

Multiple Choice

• brand of meat

• amount of cooking time

• the pan used

• the amount of fat

Multiple Choice

In the experiment on slide 15, what is the dependent variable (the one that's being affected by the change)?

• brand of meat

• amount of cooking time

• the pan used

• the amount of fat

Multiple Choice

What is the indeoendent variable (one that is changed) in Redi's experiment?

• whether the jar was covered ot nont

• The presence or absence of flies

• The amount of meat used

• The type of jar

Multiple Choice

What is the dependent variable (one that is caused by changing the other?

• whether the jar was covered ot not

John played music for his plants and measured if they grew faster.

Amy planted some flowers in organic fertilizer and some in regular fertilizer and measured them

David tried different watering schedules and tracked the plant growth.

Min investigated if talking to plants would improve their growth.

Oliver varied rhe temperature atwhich seeds were kept and tracked their germination rates

After conducting the experiment, it was concluded that fertilizing the geranium plants did indeed make them blossom.

The seeds did not grow faster when an electric current traveled through, disproving Stephen's hypothesis.

Adding more sunlight to the plants did make them grow taller, confirming Emily's hypothesis.

Using a different type of soil resulted in healthier plants, as Michael predicted.
