1 5 th Grade Science Properties of Matter

2 matter Anything that has mass and takes up space is matter

3 volume The amount of space an object takes up Another word for volume is capacity

4 What are two properties of matter?

5 All matter has mass and takes up space.

6 atom The smallest particle that can still be identified as the matter it came from is an atom

7 molecule A molecule is made up to two or more atoms joined together. Water is a molecule made of two hydrogen atoms and one oxygen atom. This is a DNA molecule

8 nucleus The dense area in the center of an atom. Inside the nucleus of every atom are smaller particles called protons, electrons, and neutrons.

9 What is an atom and what are its parts?

10 An atom is the smallest particle of matter that still behaves like the matter it came from. An atom is made of protons, neutrons, and electrons.

11 element Matter that is made of only one kind of atom is an element. Carbon, hydrogen, and oxygen are all elements. The picture is of the element zinc in hydrogen chloride. Zinc + HCL

12 periodic table Scientists use the periodic table to organize elements. Each element has its own special place on the table. The places are decided by the characteristics of the element.

13 How are the elements arranged in the periodic table? Elements are arranged in order by their atomic number The atomic number is the number of protons in the nucleus

16 SolidLiquidGas Has definite shape Particles are close together and slow moving Has volume ids.com/files/matte r_solid.html

17 SolidLiquidGas Has a definite shape Takes on shape of container Particles are close together and slow moving Particles are farther apart and faster- moving Has volume com/files/matter_liquid.html

18 SolidLiquidGas Has a definite shape Takes on shape of container Does not have definite shape Particles are close together and move slowly Particles are farther apart and faster moving Particles are farthest apart and move rapidly Has volume Expands to take up whatever space is available com/files/matter_gas.h tml

19 How are particles arranged in solids, liquids, and gases?

20 The particles of solids are close together and slow-moving. The particles of liquids are farther apart and faster-moving than solids. The particles of gases are farthest apart and move most rapidly.

21 Draw a model representing how particles are arranged in solids, liquids, and gases. Check pg. 444 in your text for examples.

22 5 th Grade Science Chapter 14 Properties of Matter Changing States of Matter

23 Physical change-a change in state The substance is still the same substance Form changes but chemical makeup doesn’t

24 Ice changes to water—water changes to ice, frozen water is still water

25 Water changes to steam, a gas, when it is heated to its boiling point,water vapor condenses to form a liquid

26 Changing States of Matter-Water Water freezes at 0 degrees Celsius, 32 degrees Fahrenheit Water boils at 100 degrees Celsius, 212 degrees Fahrenheit emphys.htmlhttp://www.chem4kids.com/files/matter_ch emphys.html

28 Physical Properties—describe matter Melting and boiling point are physical properties (the temperature at which a substance melts or boils) State of matter is also a physical property (solid, liquid, gas) Density is a physical property Density is a measure of how closely packed an object’s atoms are ndex.html

29 Mixtures and Solutions Mixtures A combination of two or more substances The substances in a mixture aren’t permanently combined Substances can be separated from the mixture and be the same as they were before they were mixed htmlhttp://www.chem4kids.com/files/matter_mixture. html x.htmlhttp://www.chem4kids.com/files/matter_mixturee x.html

30 Mixtures and Solutions Solutions A mixture in which all parts are mixed evenly Can be combinations of gases, liquids, and even solids ture/mixture.htmlhttp://www.harcourtschool.com/activity/mix ture/mixture.html ution.htmlhttp://www.chem4kids.com/files/matter_sol ution.html

32 Other Physical Changes Breaking Crushing Cutting Bending Melting Freezing Boiling Can happen naturally People can cause changes –Water evaporating –Rain falling and causing pufflrd –People cause change Recycling paper Recycling metal

33 Chemical Properties and Changes Chemical changes change the chemical nature and properties of substances to form new substances –A match burns –Two substances mix together turn a color different from either of them –Toasting marshmallows Melt it—physical change Burn it—chemical change

34

35 Combustibility-a measure of how easily a substance will burn, or combine rapidly with oxygen Corrosion of metal—when iron combines with oxygen in the air, rust forms Gas bubbles—hydrogen peroxide on a cut A change in color--fireworks

36 Conservation of Matter Chemical changes don’t make new matter The total mass of the products that form equals the total mass of the substances that react.
