Scientific Methods

Fiona decided to make an educated guess on what would happen before she did the experiment. She decided that the Epsom salt would grow the largest crystals because epsom salt has stronger chemical bonds. This was the 4th part of her experiment. What part of the scientific methods was this?

• Hypothesis- An educated guess on what will happen

• Conclusion- When done with the experiment, discuss your findings, hypothesis, data

After the experiment Fiona discovered that her hypothesis was incorrect, the Baking Soda grew the largest. Her data showed the Baking Soda crystals grew 4x larger. She wrote up a summary of what happened. This is the 6th part of the experiment. This part is called what in the scientific methods?

• Conclusion- When done with the experiment, discuss your findings, hypothesis, data

• Research- Look for answers to your question to base your experiment on

Why do we keep everything in an experiment the same except for the variable we are testing? Hint: This is called constants

• So we can get mixed results and have a valid scientific methods based experiment

• So we are comparing apples to apples, and we will only get results based on the ine variable we are testing.

Fiona went to the science museum and saw that she could grow crystals from powders she had at home. This was the first step to her experiment. What part of the scientific methods is this?

• Hypothesis- An educated guess on what will happen

• Observe- what got you curious, what did you see?

Fiona decided to explore more and came up with a question to explore. It was "What Affect if any will different types of household powders have on growth of a crystal? " This was her second step to the experiment. What part of the scientific methods is this?

• Question- what are you going to explore and find out? The problem you want to solve

• Conclusion- When done with the experiment, discuss your findings, hypothesis, data

Fiona did some collecting of information on her experiment, and discovered that Epsom Salt Crystals grew the largest. This was the third part of her experiment. What part of the scientific methods is this?

• Research- Look for answers to your question to base your experiment on

• Observe- what got you curious, what did you see?

Fiona ran her experiment and measured the size of the crystals daily and recorder the data in a data table. This was the 5th part of her experiment. What part of the scientific methods was this?

• Hypothesis- An educated guess on what will happen

• Experiment- set it up, only change your variable you want to find answer to, collect data.

In Fionas experiment, she had an independent variable. This is the variable she had control over. What variable was the independent variable in Fionas experiment?

• The different powders

• The size of the crystals

Fiona had a dependent variable in her experiment. This is the measurable variable that changed due to what she changed. What was her dependent variable in her experiment?

• Type of powder she used

• The size of the crystals
