 * Notes from Class - Science Essentials Lesson A pgs. 1-3

Vocabulary:
 * Science -** a way or a process used to inviestigate what is happening around you. It can give you possible answers to your questions.
 * technology** -the application of science to make products or tools that people can use
 * How is science used in everyday life?**
 * doing school work, cooking, sports, taking care of pets**
 * **Scientists use prior knowledge to predict what will happen in investigations.**
 * **Types of resources used to get information: books, magazines, newspapers, videos, and websites**
 * **Skills used by Scientists: observing, measuring, classifying, and interpreting data**
 * **Tools used by scientists: rulers, thermometers, triple beam balance, graduated cylinders, clocks, calculators, microscopes, telescopes, stopwatches**
 * **Purpose of Science Journals: communicate scientifc data and results, record observations, list step by step procedures,**
 * list materials and equipment, problems that occurred during investigation, and summarize data by using data tables,graphs, and charts**


 * Lesson B Science Essentials pgs. 5-12**
 * Vocabulary:**
 * **constant- variable that stays the same in an experiment **
 * ** control- a sample that is treated like the other experimental groups except that the independent variable is not ****applied to it **


 * **dependent variable- the factor being measured in an experiment **
 * **descriptive research- type of research design that answers scientific questions through observation **
 * **experimental research design-type of research design used to answer scientific questions by testing a hypothesis ****through the use of a series of carefully controlled steps **
 *  **hypothesis- a prediction, or statement, that can be tested**
 * ** independent variable- the variable that is changed in an experiment **
 * **inference - an attempt to explain observations **
 * ** model- a representation of things that happen too slowly, too quickly, or are too big or too small to observe directly **
 * **scientific method - steps to follow to try to solve problems **
 * **bias - when scientists expect a certain result **
 * Notes from lesson: **
 * **Ways to avoid bias - use numerical measurements for data and random samples **
 * **When are models used? **
 * <span style="font-family: Arial,Helvetica,sans-serif;"> When direct observation would be too dangerous or too expensive, and to save money. **
 * **<span style="font-family: Arial,Helvetica,sans-serif;">Examples of models: tables, graphs, spreadsheets. Computers can make three dimensional models. **
 * **<span style="font-family: Arial,Helvetica,sans-serif;">Why does science use International System of Units(SI) or metric system? So they can understand each other's research and compare results. **
