Volcano Research

In this week we are making a volcano but we have to research about it.

Where is the volcano?  This volcano is in the Philippine
s.

When did it last erupt ? This volcano last erupt in 12 january 2020.
Damage it has done ? Large numbers of livestock and pets were also left behind when tens of thousands of people evacuated.
How and when was it formed? formed by the subduction of the Eurasian Plate underneath the Philippine Mobile Belt. It was formed 1707. 

Interesting random facts? Taal Volcano is a large caldera filled by Taal Lake in the Philippines. Located in the province of Batangas in philippines.

Myths / legends about it? However, Indriati Retno Palupi, a volcanologist and geologist, told AFP lightning can be created when ashes containing chemical elements react with gasses in the surrounding air.

Equipment: 

-15 ml of warm water.

-25 ml of hydrogen peroxide 

- 3 spatulas of potassium iodide into the warm water and stir it .

 

METAL AND ACID

TESTING FOR HYDROGEN GAS 

AIM: TO SHOW THAT HYDROGEN GAS IS PRODUCED WHEN A METAL REACT WITH ACID.

EQUIPMENT: A TEST TUBE, A BOILING TUBE, BUNSEN BURNER , WOODEN SPLINT , A BOTTLE OF ACID, A PIECE OF METAL, SAFETY GLASSES.

METHOD:

1. LIGHT YOUR BUNSEN BURNER.
2. ADD YOU SAMPLE OF METAL TO YOUR TEST TUBE. ADD 2 ML OF ACID.
3. CAREFULLY INVERT THE BOILING TUBE ABOVE THE TEST TUBE CONTAINING THE METAL AND ACID ( AS SHOWN IN THE DIAGRAM BELOW.

OBSERVATIONS: MAGNESIUM HYDROCHLORIDE ACID MAKE A BUBBLE AND PUT FIRE INSIDE WILL MAKE SOUND.

WHEN A METAL REACT WITH AN ACID, THE SAME TYPES OF PRODUCTS ARE ALWAYS FORMED. 

 

Science: Making salts

Making Salts 

Aim: To produce copper sulfate by reacting copper with an acid.

Equipment: Copper oxide powder, dilute (0.5 mol L-1)sulfuric acid,50 ml measuring cylinder, two 100 ml beakers, Bunsen burner, tripod, gauze mat, funnel, filter paper, Thermometer, Spatula, evaporating basin, stirring rod.
Method:

1. Add 20 ml of sulfuric acid to a 100 ml beakers. heat the acid until it reaches 70℃. Turn off your Bunsen burner.
2. Once heated, use a spatula to add pea-sized portions of copper oxide to the beaker. Stir the mixture for 30 seconds.
3. Repeat step 2 until no more will dissolve. Allow the beaker to cool.
4. Fold the filter paper and place in the fennel. Place the filter funnel into the seconds beaker.
5. Make sure the beaker is cool enough to hold at the top. The contents should still be hot. you may need your teacher to complete this step.
6. Gently swirl the contents of the beakers to mix, and then pour into the filter paper in the funnel. Allow to filter through.
7. Rinse the beaker you used to heat the mixture previously, and place it back on top of your tripod filled with 50-60 ml of water.
8. Place the evaporating basin on top of the beaker and carefully pour some of the solution from the beaker into the evaporating basin.
9. Gently heat the beaker until solution in the evaporating basin has reduced by half.
10. Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warn place where it will not be disturbed(i.e a window-sill) and observe over the next few days. Blue copper sulfate crystals should form.

Observation: When we were mixing the pea-sized in sulfuric acid it dissolve it and turn to black and when we put it on beaker and it turn to blue.

Copper oxide + Sulfuric acid → Copper fulfate + water.   

Science:Model atom

Yesterday in science we make a model  atom. I pick  a carbon

- Pick an atom form 3-10 on periodic table/
- Find out how many protons,neutrons + Electrons it has.
- Equipment: I piece of card.
                    30 cm strings
                     blue tac
                     coloured beads for protons + neutrons.
- Method: Sticks P+N beads to blue tac
                 Cut out strings form paper
                 Draw electrons onto rings
                 Create a label
                 Tape strings to back of paper so it can hang.
-Discussion-

1. What's the atomic+mass number.
2. Number of P,E,+N.
3. How does it form an ion.

• The atomic number is 6 and the mass number is 12 .
• The Number of protons is 6, number of electrons is 6 and 6 Neutrons.
• the first shell have 2 electrons and the second shell have 4 electrons we can lost the sound shell and will have 4+.   

Smoking

Smoking 

What does smoking do to your body?

Smoking can damage you lungs, You brain can have a nicotine, cigarettes has a nicotine that can effect your lungs and brain.

Long terms effects?

There are many long term effects of cigarettes, the effects are stroke,brain damage and you eyes are yellowing of whites of your eyes.

Benefits of giving up smoking?

The benefit of  giving up of smoking are stop smoking and do something earls or exercise.

Is vaping any better? A little, cigarettes doesn't give you cancer but vape doesn't but it still gives you shorten of breath.

Heart Attack

Heart Attack  

What is a heart attack?

A Heart Attack is when the flow of blood to the heart is blocked.  The blockage is the most often a build-up of fat cholesterol and another symptom that forms plaque in the artery that feeds the heart.

How do you know you're having a heart attack? 

Pressure, tightness, pain, or a squeezing or aching sensation in your chest or arms that may spread to your neck.

How to prevent it?

Taking medications can reduce your risk of a subsequent heart attack and help your damaged heart function better.

Thick/thin side- The left ventricle of your heart is larger and thicker than the right ventricle.This is because it has to pump the blood further around the body,and againds higher pressure,compared with the right ventricle.

Fat/Muscle- The fat is the white bet in the heart (heart Muscle or Myocardium)is one of three types of vertebrate muscle,with the other two being skeletal and smooth muscle and strong.

Valves- The valves let blood flow to the atria and ventricles.

Labelled top holes-Holes in the heart, are right Aorta and the superior venacava.

Pig vs sheep heart- Pig heart, is very similar in size and anatomy to human heart. sheep have a four-chambered heart, just like humans.
