| What are science skills used for? | to gather information & understand the world around you |
| This science skill uses all of the senses, not just seeing. | observing |
| When you record your observations in your field notebook, you are using which science skill? | recording data |
| Which science skill are you using when you explain or interpret your observations? | inferring |
| Making a statement about what will happen in the future based on past experience or evidence is which science skill? | predicting |
| Grouping together items that are alike in some way is which science skill? | classifying |
| This science skill allows scientists to make representations of something that is hard to study. | making models |
| Comparing observations and data to reach a conclusion about them is which science skill? | evaluating |
| Observaions must be these 3 things | Specific; True; Not an Opinion |
| You use tools and take measurements with what science skill? | observing |
| The most important science skill is | observing |
| This deals with numbers or amounts. | quantitative observation |
| This deals with descriptions that cannot be expressed in numbers. | qualitative observations |
| True or False - Inferring is the same as guessing. | False |
| True or False - Inferences are based on reasoning from what you already know. | True |
| Attempting to explain what has happened or is happening. | Inferring |
| Attempting to explain what will happen. | Predicting |
| Why do scientists classify information? | To make it easier to understand. |
| To observe or study closely is to | investigate |
| To see or notice is to | observe |
| To reach a decision is to | conclude |
| This science skill involves data tables, mathematical equations, or computer programs. | Making Models |
| "three fish" would be what kind of observation? | quantitative |
| "orange fish" would be what kind of observation? | qualitative |
| True or False - Models are representations of real things. | True |
| Name 4 reasons scientists make models. | Scientists use models when things are too big, too dangerous, too small, or harmful to the animal. |
| The way scientists study the natural world. | scientific investigation |
| These are the 3 basic steps scientists use to conduct a scientific investigation. | Observe, investigate, and conclude |
| What are the three basic steps scientists use to conduct a scientific investigation? | Scientists 1.) ask questions 2.) look for answers and 3.) form new ideas. |
| This is the study of living things, including plants, animals and microscopic life forms. | Life science |
| This is the study of the Earth and its place in the universe. | Earth and space science |
| This includes the study of energy, motion, sound, light, electricity, magnetism, and chemistry. | Physical science |
| True or False - Scientists are usually trained in the same background and follow the same interests and goals. | False |
| True or False - Many nonscience careers need a knowledge of science. | True |
| This is a measurement system based on the number 10. | metric system |
| You use this unit to measure height, width, distance, and depth. | meters |
| We measure mass using this unit. | grams |
| This is the standard used in science. | SI - International System |
| We measure volume using this unit. | Liter |
| King Henry Doesn't Usually Drink Chocolate Milk | Kilo-; Hecto-; Deka-;Unit; Deci-; Centi-; Milli- |
| These are the three metric units we usually use in science. | Kilo-; Centi-; Milli- |
| What are two reasons standard measurements are important to scientists? | They can compare data and communicate with each other about their results. |
| This is a measure of the amount of matter in an object. | mass |
| This is a measure of the force of gravity on an object. | weight |
| What are the four parts of the triple beam balance? | Pan, riders, beams, and pointer. |
| What unit is used to measure the volumn of a solid? | cubic meters or cubic centimeters using a ruler to measure a regular (rectangular) solid |
| What unit is used to measure the volume of a liquid? | liters or milliliters using a graduated cylinder to measure a liquid or irregular solid |
| The amount of space an object takes up is | volume |
| What is calculated using measurements of height, length, and width? | volume |
| How do you find the volume of a regular (rectangular) solid? | Measure the length, width and height with a ruler and multiply them together to get cubic centimeters. |
| How do you find the volume of a liquid? | You use a graduated cylinder. |
| The liquid level you look at when you are measuring with a graduated cylinder is called the | meniscus |
| Which part of the meniscus do you measure? | the bottom |
| How do you measure the volume of an irregular solid? | The displacement method - add the object to a graduated cylinder of liquid and subtract the two measurements (with and without the irregular solid) to find the volume. |
| What are the units used to measure density? | kilograms per cubic meter or grams per mL |
| What is the measure for how much mass is contained in a given space? | density |
| What is the formula to calculate density? | density = mass divided by volume (mass/volume) |
| What is the SI unit for temperature? | Kelvin |
| What is the lowest possible temperature on the Kelvin scale? | absolute zero |
| What instrument is used to measure temperature? | thermometer |
| What is the SI unit for time? | seconds (s) |
| What instrument is used to measure time? | stopwatch, clock, or timer |
