Making salt crystals - Science

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

Equipment: 

• Copper oxide powder
• Dilute (0.5 mol L-1) sulfuric acid
• 50ml measuring cylinder
• two 100ml beakers
• Bunsen burner
• Tripod
• Gauze mat
• Funnel
• Filter paper
• Thermometer
• Spatula
• Evaporating basin
• Stirring rod

Method:

1. Add 20ml of sulfuric acid to a 100ml beaker. 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 it in the funnel. Place the filter funnel into the second 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 beaker to mix, and then pour into the filter paper in the funnel. Allow filtering through.
7. Rinse the beaker you used to heat the mixture previously, and place it back on top of the tripod filled with 50-60ml of water.
8. Place the evaporating basin on top of the beaker and carefully pour some of the solutions from the beaker into the evaporating basin.
9. Gently heat the beaker until the solution in the evaporating basin has reduced by half.
10. Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warm place where it will not be disturbed (i.e. a window-still) and observe over the next few days. Blue copper sulfate crystals should form.

Results:

The end results turned out great and actually turned into crystals.

Discussion:

A Copper (oxide) + sulfuric (acid) >Water + copper sulfate.

Copper oxide and sulfuric added together makes water then the water turns into copper sulfate (crystal)

Conclusion:

That the acid actually made into crystals, and the chemicals reacted together.

When I find myself in times of trouble, Mother Mary comes to me
Speaking words of wisdom, let it be
And in my hour of darkness, she is standing right in front of me
Speaking words of wisdom, let it be

Let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be

And when the broken-hearted people living in the world agree
There will be an answer, let it be
For though they may be parted, there is still a chance that they will see
There will be an answer, let it be

Let it be, let it be, let it be, let it be
There will be an answer, let it be

Let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be

Let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be, be

And when the night is cloudy there is still a light that shines on me
Shinin' until tomorrow, let it be
I wake up to the sound of music, Mother Mary comes to me
Speaking words of wisdom, let it be

And let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be

And let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be

This song was made by Paul McCartney. It was inspired by his mother, Mary, who died when he was 14. Most people thought this song was a religious song because it said "mother mary" although he didn't mind people thinking that he did want people to know it was about his mother.

10Health - Bullying

 In health, we had to choose a topic that relates to Taha Whanau and to make a DLO about what we know of the topic. I chose bullying because it seem that I knew more about this specific topic than all the other topics, then we had to answer the questions that we were given in the slide. 

Music through time- traditional music

 Spirituals were a song that the slaves would sing when they needed hope, these songs were mostly sung at funerals, wedding (if allowed) and when they were working in the cotton fields. Harriet Tubman was a very famous person in the slave time and still very famous now, she is mostly known as a hero. She would sneak slaves and have them follow her through the underground railroad, these railroad would take you to the north side of America where there was no slavery or racism there. 

One of the spiritual songs ice seen is called 

In Wade in the Water

Chorus: Wade in the Water, wade in the water children.

Wade in the Water. God’s gonna trouble the water.
Who are those children all dressed in Red?
God’s gonna trouble the water.
Must be the ones that Moses led.
God’s gonna trouble the water.

Chorus

Who are those children all dressed in White?
God’s gonna trouble the water.
Must be the ones of the Israelites.
God’s gonna trouble the water.

Chorus

Who are those children all dressed in Blue?
God’s gonna trouble the water.
Must be the ones that made it through.
God’s gonna trouble the water.

The meaning of this song was for when the slaves would escape, they would have to walk through the rivers so the dogs and trackers couldn't catch their scent, that's how most of them successfully escaped. Black people still on this day are getting harassed for their colour of their skin, and there was a protest even about racist white people and how black people wants rights. So still this day people are still affected from racism and still fighting for their rights.
