IS PUBLIC ART A WASTE OF TIME AND MONEY

Making a metal Oxide

Aim:

To make a metal oxide and observe the difference in properties of the product compared to the reactants.

Equipment:

A piece of magnesium,Bunsen burner,Safety glasses,metal scissor tongs.

Method:

1.Light your Bunsen burner.

2.Hold your piece of magnesium in the scissor tongs.Ensure   you are  holding onto the very tip of the magnesium

3.Place the other end of the magnesium into the Bunsen flame

4.When the magnesium beings to burn,do not look directly at it,as the light emitted can permanently damage your eyes.

Observations:

Before the reaction it was a shiny metallic luster,But after the reaction it turned into a bright white light.

Equation of this reaction:

Magnesium + Oxygen = Magnesium oxide  

IS THERE A END TO SPACE

I wonder if There a end to space

Astronomers think space might be infinite with energy, galaxies, etc distributed practically the same as it is in the observable universe. If it is, that has some seriously weird implications for what lies out there. Beyond the Hubble Volume you won't just find more, different planets

observable universe:

The observable universe is a spherical region of the universe comprising all matter that can be observed from Earth at the present time

Testing for Hydrogen Gas

Testing for Hydrogen Gas

Aim:To show the hydrogen gas is produced when a metal reacts 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 your sample of metal to your test tube. Add to mL of acid
3. Carefully invert the boiling tube above the test tube containing the metal and acid.
4. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas.
5. When you think the test tube is full, your lab partner should light a wooden splint
6. Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.

in English this is what our discussion is this week

F Shape

F Shapes

• Two pieces of ferrous steel are supplied.
• Clean both pieces with emery paper and add engineering blue.
• Mark out one piece exactly to the given measurements with a scriber.
• Use the correct procedure for cutting out.
• Place that piece over the second B.M.S and mark out at cut.
• File to fit.
• Use finishing techniques. 

In metal we were given two project to choose from and one of them was to F shapes that fit together, and i went with this one, this project took some time but we managed to achieve in the end, there were some minor mistakes that i have learnt from which i will make sure i wont make if i have the chance to make it again. and hopefully it will be perfect

the measurements are 60 mm long and 25 mm wide with two 15 mm cut outs

 
 


at the end of the the project i spray painted it red on one side and yellow on the other as my finish
