| Question | Answer |
|---|---|
| Why do bioloigst ask questions? | To help them understand living systems. |
| What is a hypothesis? | a possible explanation for a set of observations or a possible answer to a scientific question. |
| What are variables? | All factors that can change in an experiment |
| What is a controlled experiment? | An experiment in which only one variable is changed at a time |
| Why do scientist design experiments? | To test their hypothesis. |
| What is a balance? | a tool used to measure the mass of objects |
| What is a graduated cylinder? | a beaker marked in intervals that is used to measure volume |
| What is a microscope? | a tool used to produce magnified images of small objects |
| What is a spring scale? | a tool used to measure weight and force |
| What is a thermometer? | a tool used to measure temperature |
| What is a test tube? | a cylindrical tube, usually smaller than a beaker, that is open at one end and closed at the other |
| After gatherin and interpreting data, what do scientist do? | scientists draw conclusions about their hypotheses |
| Why do scientist communicate? | Communicating results helps scientists learn from one another. |
| What do scientist do when an experiment is done? | When an experiment is done, scientists analyze the data. |
| How do scientist present data? | Scientists use tables, charts, and graphs to organize, interpret, and present data |
| What do observations involve? | Many observations involve the senses of sight, hearing, touch, and smell |
| What questions do biologist ask? | The questions that biologists ask typically come from observations of the natural world. |
| How must a hypothesis be phrased? | A hypothesis must be phrased in the form of a statement |
| Why must the hypothesis be testable? | Because hypotheses must be testable, the questions that biologists base their hypotheses on must also be testable. |
| What is an important part of scientific investigation? | communication |
| what are variable? | All factors that can change in an experiment are called variables |
| What is a controlled experiment? | An experiment in which only one variable is changed at a time is called a controlled experiment. |
| What is a manipulated variable? | The variable that is purposely changed to test a hypothesis is called the manipulated variable. |
| What is the factor that may change in response to the manipulated variable? | The factor that may change in response to the manipulated variable is called the responding variable. Responding variables are also sometimes called dependent variables. |
| What are constants? | All of the other variables or factors, besides the manipulated and responding variables, are known as controlled variables or constants. |
