For this experience, we needed :

-Equiment as plastic glasses, spoon, ultraviolet light and gratuated cylinder.

-Subtances as borax, polyvinyl alcohol, glowing coloring subtances (eosin, fluorescein, methylene blue and soft drink with quinina.

 

Protocol :

We add four drops of colorant in three glasses (eosin in the first glass, fluorescein in the second glass and metylene blue in the third). Then, we mix it to make a substance homogenous.

 

Observations:

We can take the slime in our hands during few minutes. With ultraviolet light, it porduces a glowing light. It takes the shape of the container but only during few minutes and it's slow.

 

 

Conclusion :

The slime is liquid because it takes the shape of the container but it slow

it's a secondary light source.

(: The Slime :)

(science experiment 2)

 

 

Materials :

 

We use plastic glasses, a spoon, an ultraviolet light and a graduated cylinder.

We use a lot of substances, like borax, polyvinyl alcohol, glowing coloring substances ( eosin, fluorescein, methylene blue ) and a soft drink with quinina .

 

Experiment :

 

We mix borax, polyvinyl alcohol and glowing substances         ( eosin, fluoroscein, methylene blue and quinina ).

 

How does it work?

 

The contact of borax and polyvinyl alcohol produces a sticky and slimy substance. It glows in front of ultraviolet light.

 

Conclusion : 

 

The slime is a secondary source of light; it diffuses the ultraviolet light, it doesn't produce any.

The Slime isn't solid ; it has characteristics of a liquid :

Its surface is always flat and horizontal,

it takes the shape of its container

and

you can't hold it with your fingers.

The $lime

 

 

Materials:

We use plastic glasses, a spoon, ultraviolet light, gratuated cylinder, borax, polyvinyl alcohol, glowing, coloring substances (eosin, fluorescein and methylene blue), soft drink with quinina and U$!!

Experiment:

Mix borax, polyvinyl alcohol, and glowing subtances each three plastic glasses.A jelly immediately sticks to the spoon. Keep stirring and squeeze the substance against the side of the glass until the substance is homogeneous.In front of the camera, pick up all the slimes between your fingers and manipulate them with classical white light and then do the same with ultraviolet light only

Observation:

First it sticks to your fingers. Then it slowly flows down on the table just as jelly. It takes the shape of the glass.

Conclusion:

The slime is liquid.

The slime diffuses (spreads in all directions) another source's light as a consequence it's a secondary light source.

We mix it and we finaly add the slime with different colors.

 

How does it work

 

The contact of borax and polyvinyl alcohol produces a sticky and slimy substance. It glows in front of ultraviolet light.

 

Conclusion

 

The slimes diffuses (spreads in all directions) another source's light as a consequence it's a secondary light source.

The slime is liquid.

 The slime

 

 

Here are the substances and the material we need:

  • Borax (sodium tetraborate)
  • Polyvinyl alcohol
  • Glowing, coloring (eosin, fluorescein, methylene blue)
  • Soda with quinina

 

  • Plastic glasses
  • A spoon
  • Ultraviolet light
  • Graduated cylinder

 

Protocol:

We mix borax, polyvinyl, coloring substances and soda with quinina in a plastic glass.

 

 

What do we happens ?

We happens a sticky jelly which flows on the table. It takes slowly the shape of its container; but we can take it with our fingers. The slime is a secondary source of light because it diffuses the ultraviolet rays in all directions.

As it takes the shape of its container, it's liquid !

The Slime

 

Safety : Don't forget to put your gloves, if you forget it, your hands became dirty.

 

Material :

Equipment - To make the slime, we need a plastic glasses, a spoon, a ultraviolet light and a graduated cylinder.

 

Substance - We need the borax, poyvinyl acohol, glowing, coloring substance ( eosin, fluorescein, methylene blue ), soft drink with quinina.

 

Protocol :

To make the slime we mix the borax, polyvinyl alcohol, and some coloring substances in a plastic glasses during few minutes.

 

Observations :

1) What happens when you take it in your hands ?

- If you take the slime in your hands, it sticks to you and it flows on your table.

2) What do you see when you put it under an ultraviolet light ?

- We see a glowing light. It diffuses the ultraviolet light.

 

Conclusion :

The slime is a liquid , it looks like a solid because we can take it in our hands but it's only for few seconds ! It's really a liquid. because it doesn't have it's own shape.

The slime diffuses another souce's light as a consequence it's a secondary light source.

Science experiment n°2

THE SLIME

 

 


Equipements                                                            Substances

-Plastic Glasses                                     -Borax (also know as sodium tetraborate)

-A spoon                                                -Polyvinyl alcohol

-Ultraviolet light                                      -Glowing, coloring substances (eosin,

-Graduated cylinder                                 fluorescein, methylene blue)
                                                             -Soft dirnk with quinina

 

Experiment

We take four glasses and we pour 10 ml of borax in each with colorant (Eosin or fluorescein or methylene blue) and in the last, we add quinina. We mix it to make the substance homogenous.

After, we add 100 ml of polyvinyl alcohol in the four glasses, while we stir continuously with the spoon.

Don't stop this movement until the substance is viscous but not sticky.

We must manipulate the substance and pick up all the slime between your fingers and we can juggle and try things.
Put the slimes back in the glasses and observe what happens.

What can you do with slime?

We can :

  • Juggle with this.
  • Hold it with our fingers.
  • Handle as we want.
  • Manipulate the substance with ultraviolet light.       

 

Solid or Liquid ?

The slime is liquid because it takes the shape of its container and it has its own shape. The surface is always flat and horizontal. This is a characteristics of liquid.

Primary or Secondary Light Source ?

The slime is a secondary light source because it diffuses ultraviolet light.

Luminescent chemical reaction

 

 

Materials :

For this experient, we use four test tubes, two yogurt pots, one plastic pipette, graduated cylinder and glasses.

 

We use subtances such as luminol, hydrogen paroxide, glowing, coloring substances and potacium ferricyanide.

 

 

Experiment :

  •  We add 20 mLs of potassium ferricyanide with a graduated cylinder. We pour that in a yogurt pot.
  • With the plastic pipette, pour 5 mLs of potassium ferricyanide in each of the four test tubes.
  • We add two drops of colorant and mix it (to make the subtance homogenous).
  • We pour four drops of hydrogen paroxide in each tube and we put the pipette in the yogurt pot. We do rinse immediately.
  • We measure 20mLs of luminol with a gratuated cylinder.
  • We pour the luminol in a new yogurt pot.
  • And finally, we pour drops of luminol in the test tube and we observe the outcome.

How does it work?

The contact of the luminol and the potassium ferricyanide produces a colored light.

 

Conclusion :

This chemical reaction produces its own light as a consequence it's a primary light source.

Luminescent chemical reaction

 

Materials

luminol, hydrogen peroxide, glowin, coloring substances (eosin, fluorescein, methylene blue), potassium ferricyanide.

 

Experiment

I have 5ml of potassium ferricyanide and 4 drops of hydrogen peroxide in each of the 4 test tubes, and i add in the second tube two drops of eosin, in the third tube two drops of fluorescein and in the last two drops of methylene blue, for finish i add luminol in all of them. This reaction create a glowing light in the tube.

 

How does it work ?

The chemical reaction between hydrogen peroxide and luminol make a source of light, this light emission lasts approximatly 5 sec, but when the chemical reaction is over, the production of light ends.

 

 

Conclusion

This chemical reaction produes its own light as a consequence it's a primary light source
