1. Mrs. Garner’s 5 th Grade Science Class

2.   Atoms are the smallest part of an element; the building blocks of matter. Atoms

3.   Matter is anything that has mass and takes up space. Matter

4.   Molecules are particles that are made up of two or more atoms of the same or different elements. Molecules

5.   The three typical forms of matter are: solids, liquids, and gases; the states of water are: ice (solid), liquid water, and vapor (steam) States of Matter

6.   Solids- state of matter with a definite shape and volume  Liquids- state of matter with a definite volume but no definite shape; Liquids take the shape of their container!  Gases- state of matter with no definite volume or shape; examples: water vapor; steam  Evaporate : the changing of a liquid to a gas Defining the States of Matter: Solids, Liquids, and Gases

7.  States of water can change when a change of temperature is involved. Increase the Temperature--- solid to a liquid & liquid to a gas Decrease the Temperature---- gas to a liquid & liquid to a solid

8.   Color, size, shape, and the texture (the way it feels) are the properties or characteristics of matter. Properties of Matter

9.   ** Color  ** Luster (shine)  **Shape  **Density (Mass)  ** Texture (how it feels) Physical Properties of a Substance

10.   Sometimes matter is too small to be seen without magnification. Microscopes and Hand Lenses

11.   the amount of matter in an object  how heavy something is without gravity  measured in grams Mass

12.   Weight is the measure of the pull of gravity on an object. Weight

13.  Comparing Mass & Weight Mass  -the measure of the amount of matter in an object Weight  - the measure of the pull of gravity on an object

14.   Volume is the amount of space that matter takes up. Volume

15.   - the science that deals with the characteristics of elements, the changes that take place to form substances, and the laws of their behavior Chemistry

16.  Matter Can Undergo Two Different Types of Changes Physical ChangeChemical Change

17.   -the shape or form of a substance becomes different, but the properties of the substance stays the same; it’s a change in the size, shape, or state of matter that does NOT CREATE A NEW KIND OF MATTER;  -Example- changing water into ice, or ice melting into water, water boiling into a vapor Physical Change

18.   -a change in matter that produces new kinds of matter with different properties; atoms are arranged into new molecules  -Examples- Burning, rusting, explosions, acid Chemical Change

19.   A chemical reaction happens when two or molecules interact and something happens or changes. Chemical Reaction

20.  Clues That a Chemical Change Has Taken Place :  Change in : color, temperature, odor  Bubbles or Fizzing  Burning or Rusting

21.   Measurement is finding a number that shows the size or amount of something.  There are two main “Systems of Measurement”: Metric and US Standard. Measurement

22.   The metric system is a system measurement that uses multiples of 10.  Length: 1 cm= 10 mm, 1 m= 100 cm, 1 km= 1,000 m  Volume: 1 L= 1,000 mL  Mass: 1 kg = 1,000 g Metric System
