Term | Definition |

Observation | Is an important part of studying the world. Observations may lead to questions that you want to find out. |
Prediction | Is to make a statement about what will happen under a certain condition. |
Estimating | Is an approximate guess about something. |
Units of measurement used for length, area, or perimeter. | Metric: Millimeter, centimeter, meter, kilometer. Customary: Inch, foot, yard, mile. |
Units of measurement used for weight or mass. | Metric: Milligram, centigram, gram, kilogram. Customary: Ounces, pounds, tons. |
Units of measurement used for capacity or volume. | Metric: Milliliter, liter. Customary: Teaspoons, tablespoons, cup, pint, quart, gallon. |
Units of measurement used for temperature. | Degrees Celsius or Degrees Fahrenheit. |
Units of measurement used for time. Tools: Clock, calendar. | Second, minute, hour, day, week, month, year. |
Graduated Cylinder | Measures volume or capacity. Volume is how much space something takes up. It uses milliliters. |
Thermometer | Measures temperature. Water freezes at 32 degrees Fahrenheit or 0 Celsius. Water boils at 212 degrees Fahrenheit or 100 degrees Celsius. |
Meter stick/ruler | It measures length. It uses centimeters or inches. |
Balance scale | It measures mass. Mass is how much matter is in an object. It measures grams, kilograms, pounds or ounces. |
Stopwatch | It measures times. It can measure seconds, minutes, or hours. |
Microscope | It is used to view things that are too small for the human eye to see such as bacteria. This is called microscopic. |
Telescope | It is used to view things that are very far away. You might use a telescope to look at the moon or planets in the sky. |
Inferences | Are an important part of reaching a conclusion. An inference is a conclusion based on data that you already know or have figured out. For example, if you dog stops eating the dog food you have just bought for him, you may infer that he does not like that brand of dog food. |
Meniscus | A curved surface in a graduated cylinder when read at eye level gives you the accurate volume in the cylinder. |
Observation | using your senses to become aware of what is going on around you. |
Question/Problem | thinking about the possible problem and forming questions in your mind. |
Hypothesis | making an educated guess or prediction. |
Experiment/procedure | the steps you take to prove or solve your problem. |
Results/data | writing down or charting the information you have gathered during the experiment. |
Conclusion | a decision or judgement based on observations and inferences. You will compare it to your hypothesis to see if it is similar. |
Repeated trials | Repeated experiments in the exact same way several times to make sure the same result will occur. This is important since mistakes can and do happen when experimenting. It is also important to collect as much data as possible since this information will be used to make inferences and predictions. |
Control | When testing your hypothesis, you must be sure that your experimenting is done under this. |
Independent variables | You will change conditions and then observe how they affect your experiment. These are the conditions that you change. What changes? |
Constant | This is the condition that you leave the same in your experiment. |
Fair experiment | Is an experiment in which only one variable is change at a time in the experiment. |
