music

I enjoyed learning piano in this year. I had never played piano ever.

I felt difficult to playing guitar. It was too big to hold. And it has too many string! It made me too complicate to hold chord.

obesity

Obesity is very common disease and some people don't know why it is dangerous and some people don't care about obesity but it is very harmful so i thing people should know about obesity and manage their body. I chose to make a poster about obesity because a poster can show you detailed at a glance about obesity. And I have learned that these strategies exercise, eat healthy and monitor weight are helpful to use if you obesity. I answered my 5 big questions like this

What is obesity?

-Obesity is a medical term used to describe excess body weight.

Why is it harmful?

-Obesity increases risk of diabetes, high pressed blood, heart disease,

high blood sugar and high cholesterol.

Who is at risk for obesity? 

-Low income, above 60 years old and who likes to eat junk foods, snacks and juice. 

How does it affect us?    

- Obesity can cause lots of disease. It can affects our health.

How do you overcome obesity?

-Diet, exercise regularly and practice healthier eating habits.

Next time, ! will research more detail. I thing I worked well. I'm really proud of my poster.

energy:

  Definition:stored in an object,the ability to move something.

Different kind of energy-

light energy:the energy of the electromagnetic waves. Found in Microwaves, x-rays, and visible light.

heat energy:caused by the movement of particles. Found in all hot objects.

sound energy:energy produced by vibrating objects. Examples are speech, ultrasound and music.

chemical potential energy:Energy stored in the bonds between particles. Found in substances like petrol and food.

Electrical energy:the movement of electrically charge particles. Found in wires, generators and lighting.

Gravitational potential energy:Energy stored in objects due to their height above the ground.

Kinetic energy:Energy due to the motion of an object. Ex. Moving cars, running, swimming.

Elastic Potential energy:Energy stored in stretched or squashed objects. Examples are springs and rubber bands.

mac and cheese

 i used pasta,onion,salt,ham,milk,cheese,butter,flour and water.

• Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water during 10min.melt butter in a pan over medium heat; stir in flour and onion.pour milk into roux.mix the mixture untill it bubbling and smoothly.fold macaroni into the mixture and add some cheese and ham.

potato frittata

 we need potato,black pepper,vegetables,salt,eggs,milk and some cheese for potato fritta ta.

Heat olive oil in a medium frying pan over medium heat. Place potatoes in the pan, cover and cook about 10 minutes until tender but firm.Mix in spinach, shallots or white onion and garlic. Season with salt and pepper. Continue cooking 1 to 2 minutes, until spinach is wilted.In a medium bowl, beat together eggs and milk. Pour into the pan over the vegetables.Sprinkle with Cheddar cheese. Reduce heat to low, cover, and cook for 5 to 7 minutes or until eggs are firm.

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.
