Connor thinks that building a model of an erupting volcano using baking soda and vinegar is an example of an experimental investigation. Alyssa says it is not an experimental investigation. Which student is correct and why?

• Connor, because he plans on repeating the investigation more than once

• Alyssa, because models cannot be used in experimental investigations

• Connor, because other scientists have done this investigation in the past

• Alyssa, because a model of an erupting volcano does not have variables

Based on the picture above, what should be done to improve this experimental investigation?

• The ramps should all be the same height.

• The ramps should be made of different materials.

• The same car should be used on both ramps.

• The experimental design is correct the way it is.

When conducting an experiment, in order to get reliable results, it is important to:

• Test all forces at the same time

• Repeat the investigation several times

Before you start a lab, you make a ___________. An educated guess of what you think will occur in the lab.

• prediction

• fair test

• variable

• control variable

The variable that changes because of the independent variable.

• dependent variable

• control variable

• fair test

• science
