| What is life science? | the study of living things and how they interact with each other and their environment |
| What is the procedure in an experiment? | the steps and set of instructions followed |
| What is a hypothesis? | an "if,...then" statement that shows the relationship between the independent variable and the dependent variable by explaining why something happened as a result of changing an experimental factor |
| What is an estimate? | a measurement prediction or guess |
| What must all measurements contain? | a number, followed by the correct unit (of measurement) |
| What type of graph would be used to show how something relates to a whole value? | circle (pie) graph |
| What type of graph would be used to display trends or changes in quantity over time? | line graph |
| What type of graph is used to display categorical data? | bar graph |
| What type of data is displayed on a line graph? | quantitative and continuous data |
| What type of data is displayed on a bar graph? | quantitative and discrete data |
| What type of data is based on numerical measurements taken from exact counts or direct measurements? | quantitative data |
| What type of data is based on verbal (word) descriptions found using our senses and the skill of observation? | qualitative data |
| What is the numerical value of the metric prefix "kilo"? | 1000 |
| What is the numerical value of the metric prefix "milli"? | .001 |
| The milliliter is the equivalent of what metric unit? | the cubic centimeter |
| What is a prediction? | a suggestion of what will happen in the future based on past experiences and knowledge |
| What is an inference? | an assumption or explanation as to why an observed event happened |
| What measuring instrument is used to fine the volume of a liquid and an irregular-shaped solid? | graduated cylinder |
| What measuring instrument is used to determine the volume of a regualr-shaped solid? | metric ruler (or meter stick for larger objects) |
| What is a linear measurement? | a measurement that is one-dimensional and exists in only one plane, such as length, width, or height (depth) |
| What measuring instrument is used to find the mass of an object? | balance |
| What is the equation for calculating the volume of a regular-shaped solid? | Volume = (Length)(Width)(Height) or V=LWH |
| What is the independent variable? | the factor in an experiment that is purposely changed or manipulated |
| What is the dependent variable? | the factor that is observed and/or measured in response to the independent variable |
| What is the control in an experiment? | the level of the independent that is used as a standard of comparison |
| What science skill is used when objects are grouped according to similar characteristics? | classify |
| What science skill is used when data is placed in data tables, charts, or graphs? | organize |
| What science skill is used when a graph or data is studied for patterns or trends, often using such tools as a box-and-whisker plot or a scatter plot? | analyze |
| What are the six steps of the scientific method? | (1) State the problem. (2) Research the problem. (3) Form a hypothesis. (4) Design and conduct an experiment to test the hypothesis. (5) Observe, record, organize, and analyze data. (6) State the conclusion. |
| What are constants? | Experimental factors that remain the same |
| On what axis of a line or bar graph is the independent variable plotted? | the x- or horizontal axis |
| On what axis of a line or bar graph is the dependent variable plotted? | the y- or vertical axis |
| What is the most important lab safety rule? | Listen to and follow all teacher directions and safety precautions. |
| How is the volume of an irregulary-shaped solid determined? | Using the process of water displacement, the original volume of the water is subtracted from the final volume of the water. |
| What metric unit is used to express the volume of a liquid or an irregular-shaped solid? | the milliliter (mL) |
| What metric unit is used to express the volume of a regular-shaped solid? | the cubic centimeter (cm3) |
| What are the criteria for an IV level to be the control? | (1) It represents the normal condition. (2) It represents the setup that receives 0 (none). (3) It represents the recommended amount of something. |
| Data on a circle (pie) graph is most often expressed in what unit? | percent |
| What is the mean? | the average of data |
| One centimeter is made up of what smaller linear unit? | the millimeter (10 of them to be exact) |
