Scientific Method

A test is set up to test which brand of soda creates the biggest foam explosion when adding a Mentos candy.  Three different sodas were tested. They measured the height of the foam eruption.   What is the dependent variable?

• Brand of soda
• Number of mentos candies used
• Height of foam eruption
• Temperature of soda

The summary at the end of an experiment that explains the results. 

• conclusion
• procedures
• materials
• responding variable

How many variables can be tested in a controlled experiment?

• one
• two
• three
• as many as possible

The scientific method is made up of several:

• stones
• experiments
• problems
• steps

What is an observation?

• A scientific statement based on ideas

• Using your senses to notice what is going on around you

• To be unaware of your surroundings

• The question that you want an answer to.

This is the last step in the scientific method

• Draw a conclusion
• Record your data as results
• Share what you have learned with others
• Collaborate with others

What is a hypothesis?

• A hypothesis is the right answer to an experiment.

• A hypothesis is the wrong answer to an experiment.

• A possible explanation.

• I don't know.

What is using your 5 senses (seeing, hearing, touching, smelling, and tasting when appropriate) along with the right tools to gather information called?

• hypothesizing
• communicating
• observing
• questioning

What step does every scientific experiment begin with?

• hypothesis

• question/problem

• procedures

• conclusion

The variable that is measured.

• Controlled Variable

• Dependent Variable

• Independent Variable
