In science, we often gather information with our senses by watching, listening, smelling, and touching. For example, you may record how the color of a flower changes. What is this process called?
Stating hypotheses
Forming conclusions
Making Observations
Performing experiments
A doctor says that drinking two glasses of milk in the morning will give students more energy. Which of the following would be good scientific evidence for or against the doctor's claim?
A brochure from the doctor stating the benefits of milk
Data from scientific investigations about drinking milk in the morning
A TV advertisement that says drinking milk in the morning gives plenty of energy
Statements from five people about how drinking milk in the morning gives them energy
Which of the following is an experiment in which a person can control a variable?
Observe the behavior of ants around an anthill
Tell whether it rained every Wednesday for an entire month
Count the number of insects in a piece of ground measuring 1 meter square
Determine whether plants grow better in full sunshine or partial sunlight.
Imagine that a scientist suggests that the size of an insect population depends on the temperature. What observations must this scientist make in order to collect evidence to support his or her theory or idea?
The scientist must observe the insect population only in winter
The scientist must observe the insect population in the laboratory
The scientist must observe the insect population in different area
The scientist must observe the insect population throughout the year
Scientists are not the only ones who gather information. For example, historians gather information to describe what has happened in the past. However, scientists gather information differently than others. Which way of gathering information do only scientists use?
Reading
Observing
Recording
Experimenting

Scientist communicate their results by publishing their work. Why is it important for scientists to do this?
To learn from each other
To keep their work secret
To compete with other scientists
So the experiments are not repeated
