piano

 piano invented in Padua ,Italy by  Bartolomeo Cristofori. The first Piano looked Like a Harpsichord.When a key is pressed, a plectrum attached to a long strip of wood called a jack plucks the string to make music. This system of strings and soundboard, and the overall structure of the instrument resemble those that can be found in a piano.The piano is an acoustic instrument, meaning its sound is produced and amplified physically. In comparison, keyboards are electronic instruments with a variety of volume options, and often can produce sounds like piano, horns, strings, organs, synthesizers, and more.

distillation experiment

 distillation

aim: to separate a solute from a solvent in a solution using distillation.

equipment:a solution of saltwater,conical flask, heatproof mat, a delivery tube and bung,bunsen burner, tripod, gauze mat, retort stand, boss head and clamp

hypothesis:sugar is left in conical flask and water is evaporated 

method:

1. set up the equipment as shown in the diagram.

2. add approximately 50 ml of saltwater to your conical flask

3. light your bunsen burner ,open the air hole and gently push the busen burner under the tripod

4. heat the solution until most of solvent has been evaporated. turn off your busen burner

observation:cola is boiling and steam is coming out.

conclusion: sugar is left in conical flask and water is evaporated

chemicals and chaos

 evaporate experiment

intro:we have been learning about distillation,evaporation,dilution. 

evaporation is when liquid to gas

aim:to evaporate copper sulfate. (sulfur oxygen)- (blue liquid)

hypothesis: i think that it will be disappeared.

equipment:Copper sulfate solution, 250mL Beaker, heat proof mat, evaporating basin, element. 

method:

1. Set up element

2. Add 100mL of hot water to the beaker and place on the element.

3. Add copper sulfate to the evaporating basin until it is quarter full.

4. Carefully, place the the evaporating basin on top of the beaker. 

5. Turn on the element to 3

6. Heat the solution until most of the solvent has been evaporated and crystals of solute are forming. 

7. Turn off the element- careful not to touch as will be hot for a long time.

Oberservations: the water starts to boil up,and steam is coming out the water

Conclusion: My hypothesis was right leaving the copper sulfate disapear after the water boiled up.

solute=solid

solvent=liquid

solution=mixture

Influences and fixes

 Influences and fixes.

In some relationship are unsafe and safe.

But how do you know your in an unsafe relationship?

A unsafe relationship is when you are getting mentally hurt and physical hurt.

Violence is when you are getting hurt and have bruises and cut over you from your partner.

Backstabbing is when someone is talking behind your back and telling other people things that they don’t say to your face.

Control is when you partner is telling or yelling at you to make you do something you don’t wanna do.

Jealousy is when your partner is jealous about something you have or do that they don’t have or do.

Toxic is when they do something to hurt your feeling and tell you to do things that you don’t like or wanna do.

You should talk to someone about it and if you can’t find way to deal with it.

dilution experiment

 Serial dilution

serial dilution : repeated diluting(making it weaker)

 water + potassium permanganate - mixture/solution
