What is the Scientific Method?

The Scientific Method

is a series of steps used by researchers to study the world around us by asking questions and or stating a problem .

Scientific Method Steps

• Make an observation

• Ask a question

• Form a hypothesis

• Design an experiment

• Collect the data

• Analyze and interpret the data

• Draw conclusions and Communicate the findings

Christopher set up six tanks with equal volumes of 20 ℃ water. Three of the tanks contained water with a high salt content of 30 parts per thousand and three contained water with no salt. Christopher added an equal amount of green algae to each tank. He allowed the algae to grow in the tanks for two weeks. Then, he measured the amount of algae in each tank. Identify the question that Christopher’s experiment can best answer.

• Is the growth of algae affected by the temperature?

• Do algae grown in water with a high salt content release more oxygen than an equal amount of algae grown in water without salt?

• Do algae grow more in water with high salt content than in water without salt?

When baking soda and vinegar are combined, they create bubbles of carbon dioxide gas. Kurt combined baking soda and vinegar in 12 different beakers. In each beaker, Kurt placed two tablespoons of baking soda and one tablespoon of vinegar. He used rice vinegar in four of the beakers, white vinegar in four of the beakers, and apple cider vinegar in four of the beakers. Kurt watched the beakers and recorded the amount of time that each mixture bubbled. Identify the question that Kurt’s experiment can best answer.

• Does the type of vinegar mixed with baking soda affect the type of gas released by the mixture?

• Does the type of vinegar added to baking soda affect how long the mixture bubbles?

• Does the amount of vinegar added to baking soda affect how long the mixture of baking soda and vinegar bubbles?
