The Scientific Method
The first step in the scientific method
What is observe?
This is the formula to find the volume of a solid object
What is length x width x height?
This graph displays data over time.
What is a line graph?
Convert 0.035 L to milliliters.
What is 35 mL?
The variable that the scientist purposely changes
What is independent variable?
This tool measures liquid volume more precisely than a beaker
What is a graduated cylinder?
A student compares the amount of water absorbed by five different brands of paper towels. Which graph would be best?
What is a bar graph?
When converting from meters to centimeters, you move the decimal this many places.
What is 2 places to the right?
Factors that are kept the same throughout an experiment
What are constants?
A scientist looks at the results of an experiment and uses them to decide whether the hypothesis was supported.
What is analzying data?
What is zero degrees Celsius?
The numbers along the axis that tell you how much each interval represents are called this.
What is a scale?
4.2 grams = ___ milligrams.
What is 4,200 grams?
The group that receives the independent variable.
What is experimental group?
A student predicts, “If a plant gets more sunlight, then it will grow taller.” This is an example of this.
What is a hypothesis?
This is where you should read a graduated cylinder at.
What is the meniscus?
A student graphs temperature on the x-axis and plant growth on the y-axis.Which variable is being measured?
What is plant growth?
A piece of wire is 0.0085 km long. How many centimeters long is it?

A researcher tests a medicine. One group receives the medicine, while another receives a substance that looks identical but contains no medicine. What is the second group called?
What is the control group?
What is more trials are necessary as more trials create more reliability?
If you take an object from Earth to the Moon, its mass stays the same because this does not change.
What is the amount of mass in an object?
A scientist graphs the amount of sunlight a plant receives on the x-axis and the plant's height on the y-axis. The points generally move upward from left to right.
What does this graph suggest about the relationship between sunlight and plant height?
What is plants generally become taller as the amount of sunlight increases?
A scientist measures 2.5 liters of water. She pours the water into containers that each hold 500 milliliters. How many containers can she completely fill?
What is 5 containers?
An experiment tests whether exercise affects heart rate. The scientist changes the amount of exercise and measures heart rate. Name the independent variable, dependent variable, and one controlled variable.
What are amount of exercise, heart rate, and something such as person being tested, age of person being tested, or physical state of person being tested?
