Q1: in front of you substances mention its type (Acid or bases)? Then mention its properties.
Experiment Observation Conclusion
Put to solution of substances litmus paper The litmus paper change to red The substances is Acid
The properties of acids:
They have sour taste.
they change litmus paper to red
their chemical formula begin with Hydrogen join with atomic group except OH
------------------------------------------------------------------
Q2: in front of you substances mention its type Acid or bases? Then mention its properties.
Experiment Observation Conclusion
Put to solution of substances litmus paper The litmus paper change to blue The substances is base
( alkalis )
The properties of bases ( alkalis):
1-They have biter taste and feel slippery.
2-they change litmus paper to blue
3-their chemical formula end with OH group
-----------------------------------------------------------------
Q3: in front of you metal burn it in the air and write your observation, then write the equation.
Experiment Observation Conclusion
Hold the metal then burn it The ribbon of metal glow and White powder formed. The metal is magnesium and the product is magnesium oxide
The equation:
2Mg + O2 2 MgO (white powder)
------------------------------------------------------------------
Q4: in front of you a comb and a piece of paper prove that electric charge has electromagnetic force.
Experiment Observation Conclusion
Brush the comb with your hair or a piece of wool. The comb attracts the small piece of paper. The electric charge has electromagnetic force
------------------------------------------------------------------
Q5- shows the idea of electromagnet and mentions its structure and its use.
* The idea depends on the electric magnet is: change electric energy to magnetic energy.
electromagnet consists of :
Insulating copper wire.
wrought iron bar
dry cell ( battery )
iron filling
The use of electromagnet: used in electric bell and winches
----------------------------------------------------------------
Q6: in front of you a rock mention its name, properties, and the mineral forming it
Granite
its properties :
it is from plutonic rock
its colour is grey or pink
it is solid , rough , heavy
it exist in eastern desert and Sinai peninsula .
the mineral forming it
Quartz (silicon dioxide): it is glassy luster.
feldspar : consists of aluminium silicate and some elements as potassium , calcium or sodium
Mica: it is bright sheet or dark
---------------------------------------------------------------
Q7: in front of you mineral mention its name, properties, and the rocks
Which contains it, and then mention the properties of one the rocks forming it.
* Mica: it is bright sheet or dark brown.
* The rocks contains it: Granite - sandstone
* The properties of granite:
1-it is from plutonic rock
2-its colour is grey or pink
3-it is solid, rough, heavy
4-it exist in eastern desert and Sinai Peninsula
------------------------------------------------------------------
Q8: in front of you a rock mention its name, properties, and the mineral forming it
Basalt: it is dark colour rocks, its components can't see by naked eye
It is found in Egypt in Abou-Zaabal and El-Fayoum.
The minerals formed basalt
- Olivine (magnesium and iron silicate): it has olive colour and glassy luster
- Pyroxene: it is mixture of iron silicate and calcium
It has green colour and prism shape.
- Feldspar
