Scientific Method Examples

Imagine you're a scientist conducting a fun experiment on plants to see how different beverages affect their growth. You have a variety of plants, each in the same type of pot, with the same amount of soil and sunlight. Each plant gets a different drink; water, apple juice, or milk. Can you identify the independent variable in this experiment?

• The species of the plant

• The amount of sunlight each plant gets

• The type of pot each plant is in

• The type of beverage each plant receives

Imagine you're a curious student wanting to explore the fascinating world of exercise and its effects on the heart rate. You decide to conduct an experiment where you measure your pulse while resting, standing, walking, and even running! Can you identify the dependent variable in this exciting experiment?

• heart rate

• type of exercise

• amount of exercise

• time of day exercise occurs

Imagine you're a curious student wanting to explore the effects of different types of exercise on your heart rate. You decide to measure your pulse while you're chilling out, standing like a statue, strolling like a star, and running like a cheetah. Can you tell what the independent variable is in this fun experiment?

• heart rate

• type of exercise

• time of day that exercise occurs

Imagine you're a scientist conducting a cool experiment on plants to see how different liquids like water, apple juice, or milk affect their growth. Each plant in your lab gets a different liquid, but everything else is the same - they all have the same amount of soil, bask in the same amount of sunlight, and even groove to the same music! In this fun investigation, can you identify the controlled variables?

• Type of plant, amount of music, and sunlight

• Water, apple juice, milk

• Plant growth
