Crystalliation Blog/Chemistry

 Hi people today's post is about what we did last week in science which was making crystals with borax.

The aim of the experiment was to make crystals.

Method: Boil water in a beaker on a Gauze mat and Tripod over a Bunsen Burner. When boiled turn the gas off. Add spatula heaps of Borax, waiting for it to dissolve until adding more. When the solution is saturated, leave to cool with a pipe cleaner suspended in the beaker. 

Equipment: Beaker, borax, Heat mat, Tripod, Gauze mat, Bunsen Burner and pipe cleaner.

Conclusion: We disovolved the borax in the water, we made a concentrated solution. Useing crystallization we seprated the borax from the water.

Chemistry

 Hello bloggers and welcome back to my blog this post is about one of our experiments which was Dilution and Filtration. 

1. Which test tube had the most concentrated sample of Copper nitrate: The darkest tube

2. When we added water what were we doing to the concentration of the solution: It lightened the color

3. Which concentration of copper nitrate formed the most precipitate, why do you think this is the case: There were chemicals in the first the second, or 3. 

Equipment: 1. 4 Test tubes 2. Test tube rack the chemical solutions Copper nitrate and sodium hydroxide. 

Key terms: Filtering is when you can separate the solute (solid) from the solvent (liquid)

Separate means to slip apart 

Once the solvent has been filtered that is called the filtrate.

Mediaeval essay practice

Hello bloggers today's post is about our practice essay I based it on Mediaeval torcher devices on this doc I have listed at least 4 our 3 torcher devices I have explained how they work. These devices were based in the past.

Hope you learned something new from this post.

Term 1 refelction.

Hi bloggers 

Today's blog post is about term 1.

What I mostly enjoyed was hanging with friends and doing some of my favorite subjects like, ITC, HEC. 

What I did not like was math Pe. But over all i thought it was an okay term

Chemistry

 Chemistry.

Aim: See how long water would last in a paper box with a flame under the box.

Equipment: Bunsen burner, heat mat, Try pod, gas, water, paper, glue safety googles, lighter, and Water beacon.

Saftey steps: Saftey googles, walking inside, hair tied up, being and carefully of the fire.

So to do this experiment you will need the stuff I have named up the top and follow the safety steps.

First, you will need to make a paper box make sure the box is strong enough to hold water, and make sure it does not leak water. Set up the Bunson burner make sure it is plugged into a gas source make sure the hole in the bottom side of the bunsen burner is closed. Turn the gas on and get a lighter to light the top of the bunsen burner make sure the flame is blue let it heat up, fill the paper box with water then put it on top of the try pod which will go on top of the Bunson burner. Make sure you have a heat mat underneath the Bunson burner time how long it last without bursting into flames.

Bullying

 What is Bullying?

The behaviour of a person who hurts or frightens someone smaller or less powerful, often forcing that person to do something they do not want to do: Bullying is a problem in many schools.

Whether bullying is physical, verbal, or social (relational), four widely-accepted factors can be used to identify it:

Bullying is deliberate - harming another person intentionally.

Bullying involves a misuse of power in a relationship.

Bullying is usually not a one-off - it is repeated, or has the potential to be repeated over time

Bullying involves behaviour that can cause harm - it is not a normal part of growing up.

Physical bullying:

This involves hurting someone, or damaging or stealing their belongings. It includes:

• hitting, kicking, pinching, spitting, biting
• tripping, shoving or intimidating another person
• mean or rude hand gestures
• touching another person when they don't want you to
• being made afraid of being hurt
• stealing or damaging possesions.

Verbal bullying 

This involves saying or writing mean things. It includes:

• name calling
• teasing someone in a hurtful way
• making fun of someone
• being sarcastic in a hurtful way
• offensive comments, insults or jokes about someone and their family because of their race, culture, religion, disability or sexuality.
• mean comments about someone's body or physical characteristics such as their weight or height
• hurtful comments about the way someone looks or behaves
• inappropriate sexual comments
• taunting
• threatening to cause harm.

This involves hurting someone's relationships or reputation. It includes:

• ignoring or leaving someone out on purpose

Savoury Bread cases.

Welcome back people to my blog, last Friday we made bread cases. This is the first actual cooking part we have done this term, this is a pretty easy thing to make. It is basically baked beans on toast, First, we had to collect our equipment: Cheese, Bread, Margarine, Baked beans, and spaghett. 

We then grated the cheese, buttered the bread, cut the crust of the bread place bread in a muffin tray, bake the bread at 180 degrees for like 5 minutes. Take the muffin tray out, put in fillings I used bake beans ham and cheese. Place the tray back in the oven for at least 8 minutes. Then take out of the oven let cool down and enjoy.

Here is another way to make them: Click here
