5th Grade Science Properties Of Matter DIVITO 2011-2012 5th Grade Science Properties Of Matter

Anything that has mass and takes up space is matter. Matter is… Anything that has mass and takes up space is matter.

What is Volume? The amount of space an object takes up Another word for volume is capacity

What are Two Properties of Matter? 2) All matter has volume 1) All matter has mass

An Atom is… the smallest particle that can still be identified as the matter it came from.

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.

What is the nucleus? The dense area in the center of an atom. Inside the nucleus of every atom are smaller particles called protons and neutrons. Electrons fly around the outer limits of the atom.

What is an atom? An atom is the smallest particle of matter that still behaves like the matter it came from. What is an atom made of? An atom is made of protons, neutrons, and electrons. http://www.harcourtschool.com/activity/science_up_close/519/deploy/interface.html

What is an Element? Matter that is made of only one kind of atom is an element. Carbon, hydrogen, and oxygen are all elements. Aluminum foil is an example of an element.

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.

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

What are the 3 States of Matter? Review the following website to learn about the three states of matter and the properties of each state. 1)http://www.harcourtschool.com/activity/states_of_matter/index.html 2)http://www.chem4kids.com/files/matter_changes.html 3) Now complete the chart on the following slide in your workbooks. Use a ruler and share yor answers with your group after you are done.

Solid Liquid Gas Describe the way the shape behaves Describe the way the particles behaves Describe the way the volume behaves

Particles are close together and slow moving Solid Liquid Gas Has definite shape Particles are close together and slow moving Has volume http://www.chem4kids.com/files/matter_solid.html

Takes on shape of container Solid Liquid Gas 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 http://www.chem4kids.com/files/matter_liquid.html

Takes on shape of container Solid Liquid Gas Has a definite shape Takes on shape of container Does not have definite shape, takes shape of the container. Particles are close together and move slowly Particles are farther apart and faster moving Particles are farthest apart and move rapidly Has volume that stays the same Volume expands to take up whatever space is available

Section One Review Questions What is matter? What is the smallest matter? What is a water molecule made of? What are the three states of matter?

Section One Review Answers What is matter? Matter is anything that has mass and takes up space. 2) What is the smallest matter? An Atom is the smallest matter. 3) What is a water molecule made of? A water molecule is made of two Oxygen molecules and one larger Hydrogen molecule. H20. 4) What are the three states of matter? The three states of matter are: Solid, Liquid and Gas.

Section One Quiz What example was given for an element? What is inside the nucleus? What is another word for volume? What is a molecule? What is the periodic table for?

Section One Quiz Answers What example was given for an element? Aluminum What is inside the nucleus? Protons and electrons. What is another word for volume? Capacity. What is a molecule? Two or more atoms joined together What is the periodic table for? It is used to organize all the elements.

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

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

Draw a model representing how particles are arranged in solids, liquids, and gases.

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

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

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

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

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 http://www.harcourtschool.com/activity/hotplate/index.html

Mixtures and Solutions 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 http://www.chem4kids.com/files/matter_mixture.html http://www.chem4kids.com/files/matter_mixtureex.html

Mixtures and Solutions A mixture in which all parts are mixed evenly Can be combinations of gases, liquids, and even solids http://www.harcourtschool.com/activity/mixture/mixture.html http://www.chem4kids.com/files/matter_solution.html

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

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

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

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.
