• Magnet attract some objects and not others.

• Objects magnet attracts are made of certain metals.

• Is hard, shiny material found in Earth’s ground.

• Magnets attract metal called iron, and some other metals too.

Metal

4


• Anything attracts metals has the property of magnetism.

• Magnetism is very useful property. How??

• It holds things

• It is used to sort certain metals from other objects.


5


Do you need iron in your body?Yes, you need it every day to stay healthy.

From what can you get iron?From meat and dark green vegetables like spinach.


6


• Iron is often mixed with other materials to make steel.

• Steel is strong and lasts a long time.

• It is used to build things like bridges, railroads, and cars.


7


Other metals such as: gold, silver, copper, and aluminum.Each metal has its own properties.Copper and Aluminum soft and light.Copper used to make pipes.

Aluminum used to make airplanes.


8


• Gold is soft, yellow, and shiny

• Silver shiny too.• They are used to make

jewelry.Vocabulary:MetalElementAtomCompoundChemical changeObjectives:I will be able to know:1-what is magnet and its properties.2-elements are the building blocks of matter.3-differentiate between physical and chemical change.

What are the building blocks of matter?

the metals iron, gold, silver and copper are elements.

the building blocks of matter.


Elements

10


• There are more than 100 different elements.

• They make up all the matter in the world.

• Some elements such as iron and copper are solids

• Other elements such as mercury are liquids

• Others such as helium gases

• Each element has its own properties.


11


• Elements join together in different ways .

• They form everything on Earth.

• All elements are made of atoms.

• Is the smallest particle of matter.

• It is too small to see with your eyes.

• The atoms that make up one element are all alike.


Atom

12


• Long ago people thought the only elements were air, water, fire and Earth.

• But today they understand they are not elements.

• The tusks of the a walrus contain calcium, which is element.


13


• Water can break apart into 2 gases( hydrogen + oxygen) both of these gases are elements.

• H2O = 2Hydrogen + 1 Oxygen

• Wood when heated, it gives off carbon gases, so carbon is element but wood isn’t.


14


• The periodic table • It lists all the elements.• The letters in each box stand

for the name of the elements.Vocabulary:MetalElementAtomCompoundChemical changeObjectives:I will be able to know:1-what is magnet and its properties.2-elements are the building blocks of matter.3-differentiate between physical and chemical change.

15


What happens when Elements join together? How 100 elements form all materials on Earth?Elements join together to form compounds.

Forms when you put 2 or more elements together.They have different properties from the elements they are made of.Ex. Rust = iron + oxygen


Compound

16


Common CompoundsSalt Rust Wood

Sodium+ chloride

Iron+ oxygen

Carbon+ oxygen+hydrogen


17


• When compound forms it is chemical change.

• Changes in the matter itself.• You start with one kind and

end with another.• Ex. Burning wood ash+

gases• Rust is very different from

iron• Cooking• Your body uses food for its

energy.
