What is Science?
| Question | Answer |
|---|---|
| What system studies the principles of the world? | Science |
| What system studies machines & other systems that meet humans? | Technology |
| What is a tested possible explanaion of a natural event? | Scientific Theory |
| What is a summary of an observed natural event? | Scientific Law |
| What is applying logic & reason to observations & conclusions? | Critical Thinking |
| What is a series of logical steps to follow in order to solve problems? | Scientific Method |
| What is anything that can change in an experiment? | Variable |
| Who makes objective observations? | Scientist |
| Who also confirms results by repeating experiments & learns more by designing & conducting new experiments? | Scientist |
| What are supported by repeated observation but may be changed when observations are made that are not consistent with predictions? | Scientific Laws & Theories |
| What are used to represent real situations & to make predictions? | Models |
| What is a straight line distance between any two points? | Length |
| What is a measure of the quanity of matter in an object? | Mass |
| What is a measure of space, such as the capacity of a container? | Volume |
| What is fore with which gravity pulls on a quantity of matter? | Weight |
| What kind of a method does a person ask question, collect data about the question, formss a hypothesis, tests the hypothesis, draws conclusion, & if necessary, modifies te hypothesis based on results? | Scientific Method |
| What is an only one factor, the variable, is tested? | Ideal Experiment |
| What has seven units? | SI |
| What is a value written as a simple number multiplied by a power of 10? | Scientific Notation |
| What is the degree of exactness of a measurement? | Precision |
| What is the digits in a measurement that are known with certainty? | Significant Figures |
| What is the extent to which a measurement approaches the true value? | Accuracy |
| What helps you understand experimental results? | Representing Scientific Data with graphs |
| What is useful for writing very large & very small measurements B/C it uses powers of 10 instead of Strings of Zeros? | Scientific Notation |
| What tells others how precisely a measurement was made? | Expressing Data with significant figures |
| Things measured by mass: | Water Bottle, Measuring Cup of Oil, Butter, Coin, CD |
| Things measured by volume: | Cube, Red Liquid in a bottle, Purple Liquid in a measuring cup & sugar in a teaspoon. |
| Things measured by length: | Diameter of coins, Football Field, pencil. |
| Why is scientific method similar to critical thinking? | Scientific Method: a series of logical steps to follow in order to solve problems. Critical Thinking: applying logic & reason to observations & conclusions. |
| What is a hypothesis? | A prediction |
| How is a hypothesis used? | By doing a prediction before doing experiments. |
| Why should no experiments be called no failure? | They're all observations of real happenings in the world. |
| How are scientists tools related to science & technology? | Sometimes scientists need more than observations & they would need microscope or other tools to test their hypothesis |
| What kind of data is best displayed as a line graph? | Data that changes best represented by a line graph. |
| What kind of data that is best displayed as a pie chart? | Displayed data that are parts of a whole data, ingriedients or nutrients in a recipe. |
| What's the difference between accuracy & precision? | Precision: the extent to which a measurement approaches the true value. Accuracy: The extent to which a measurement approaches the true value. |
| What is the degree of exactness of a measurement? | Precision |
| What are the digits in a measurement that are known with certainty? | Significant Figures |
| What is the extent to which a measurement approaches the true value? | Accuracy |
| What is a value written as a simple number multiplied by a power of 10? | Scientific Notation |
| Which pound weighs more: feathers or lead? | Pound = Pound |
| What is not included in physical science? | Zoology |
| What science deals most with energy & forces? | Physics |
| What do superconductors use to build computers? | Technology |
| What does a balance use to measure? | Mass |
| What is an SI base unit? | ? |
| What is the quantity 5.85 X 104 m is equivalent? | 58500 meters |
| What has 2 significant figures? | ? |
| What is the composition of mixture of gases that makes up our air is best represented on what kind of graph? | Pie Chart |
| What results you expect is an example? | Scientific Method |
