Geyser Experiments with Candies

Anna Kate, a fifth grader, conducts a science fair experiment to explore the effects of different candies and ingredients on the size of geysers produced when dropped into Diet Coke. She tests various candies and compares caffeine-free and regular Diet Coke, as well as Diet Coke and regular Coke. Her hypotheses are partially confirmed, with Mentos producing the largest geysers, caffeine-free Diet Coke creating larger explosions than regular, and Diet Coke outperforming regular Coke. Anna concludes that while much of the information online is accurate, some claims are not entirely true.

What is the main objective of Anna Kate's science fair experiment?

• To test the impact of bottle size on geyser height.

• To determine if different candies can produce geysers.

• To explore the effects of temperature on geyser size.

• To find out if other sodas can create geysers.

Which ingredient does Anna hypothesize will result in a smaller geyser?

• Carbonation

• Caffeine

• Sugar

• Aspartame

What is the first step in setting up the experiments?

• Choosing the location

• Assembling the materials

• Inviting participants

• Recording the results

Which candy was used as a comparison standard in the first experiment?

• Tic Tacs

• Skittles

• Mentos

• Eclipse Gum

In the second experiment, what was compared?

• Different types of candies

• Caffeine-free and regular diet coke

• Diet coke and regular coke

• Different bottle sizes

What was the focus of the third experiment?

• Testing the effect of temperature

• Comparing diet coke and regular coke

• Testing different bottle sizes

• Comparing different candies

Which candy produced the largest geyser in the first experiment?

• Tic Tacs

• Mentos

• Eclipse Gum

• Skittles

What was the result of the caffeine-free diet coke compared to regular diet coke?

• Regular diet coke produced a larger geyser

• Caffeine-free produced a smaller geyser

• Caffeine-free produced a larger geyser

• Both produced the same size geyser

What conclusion did Anna draw about the role of caffeine in the experiment?

• Caffeine is crucial for a large geyser

• Caffeine increases geyser size

• Caffeine has no effect on geyser size

• Caffeine reduces geyser size

What did Anna learn about the information available on the internet regarding this experiment?

• It is completely misleading

• Most of it is accurate

• None of it is accurate

• All of it is accurate
