Electric Circuit

My electric circuit

        Wen we use an positive energy and negative energy they can move the ventilator.

   Experiment of electricity (with lemons):

                          

                           Elements:

2 lemons

Knife

4 coins

4 screws

Copper Cable

3 clamps

Insert, in a lemon, two objects facts of different metals, for example a screw galvanized a currency copper. these two objects work as electrodes, causing an electrochemical reaction-mediated juice lemon generated by a small amount of power.

Distilation

              Dislation

When two liquids that evaporate at a different rate ( different roling point)

Liquid is heated; one evaporates first and form vapour; this vapour is collected and cooled

To do dis experiment we need: bunsen burner, round-bottom flask,fracting column, thermometer, water out,condenser and water in.

We put the water in the round-bottom Column.

Then we ingnite the Bunsen burner

The the water pass in the tubes and falls in the recipient

filtration 3

                              Filtration

             

Components:

      Rocks

      Coarse sand

      Fine sand

      Botell

      Water

      Elastic band

      Coffee filter

             Information:

We had to bring a bottle of home and with it make a filtration.

first we had to cut the bottle on the part of the lid, we could put the elements to make a water filtration and the best filtration we look and put in a video.

                   Definition:

      

Is any of vaious mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium throught wich only the fluid can pass.

EXPERIMENT

FILTRATION

Materials

1. We need plastic bottle
2. We need things, examples:flower…
3. We put materials in the bottle
4. Over the materials we put water
5. The water falls below the materials

What happen when the filtration occurs?

The water falls below the materials

And the name of that is filtration

How to do a filtration?

1.We cut the bottle

2. With zeal we paste the tho part

3.In the  cap of the bottle we make a hole

4.We put materials in the bottle

5.We trough water inside the bottle

6.We look the filtration process

Chemical changes

Combustion

Is a chemical reaction that produce energy.

During the combustion the wood make energy and burn and become in smoke.

Oxidation

Some metals have a chemical reaction.

During the oxidation some metals oxidate.

Fermentation

is a process catabólico oxidation incomplete, which does not require oxygen and end product is an organic compound. according to the final products, there are various types of fermentation.

Separating mixtures

There are two types of mixtures

Heterogeneous mixture:

Is more easy for separate.

Two rocks

Homogeneous mixture:

Is very difficult for separate.

Colacao with milk

Are a lot forms for separate objects:

• Filtration
• Evaporation
• Distillation

Filtration

Evaporation

Distillation

The filtration is an operation that is used to separate particles solid, in suspension of a liquid or gas the effect of gravity empty or suspension exerted

                          Filtration

This experiment is to put different filters in middle part of the bottle, then pour water bottle and water comes out without bacteria

Evaporation

Evaporation there is any temperature and affects molecules that are in the free surface of the liquid

Distillation

Process by which the substance volatile a mixture separates other non-it is by evaporation and subsequent condensation of

Filtration

To do this experiment we need a bottle of two liters. Then we take some ingredients, like: sand and flowers.The best option to do this is: first take grass, second: we take some stones and then the water. The objective is put water mixed with sand and then the water fall down. But the water doesn’t have the sand.

Experiment of the barrel

In this experiment we use some things:

-A barrel

-Cork

-A water

-Blow-pipe

          

Information:

In this experiment we put water in the canon and then we put THE firme in the canon and THE cork left fired.

Experiment

In this experiment we use things:

-Glas clok

-Water

-Artificial snow

-paper

-Gloves

Information:

to take water in the snow artificial snow was soft. And in this experiment we put artificial snow in the glas clock.and we put water in the artificial snow.The volume of liquids is measured in measuring cylinders. The value of the measuring line on the cylinder is the volume
