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

ergonomic and anthropocentric

ergonomic

Human factors and ergonomics, is the application of psychological and physiological principles to the design of products

anthropometrics

sourced from this website

Anthropometry refers to the measurement of the human individual. An early tool of physical anthropology, it has been used for identification, for the purposes of understanding human

In English we are doing a persuasive discussion on if Technology is Useful to Increase Student Engagement and Achievement.

Here are my Pros and Cons on this topic

Making salts

Aim: To produce sodium chloride salt by carrying out a neutralisation reaction

1.  using the measuring cylinder measure 10 ml of HCI and pour it into your 50 ml beaker. add dilute NaOH a few at a time while stirring with a glass rod. 
2. Every 10-15 drops stop adding the NaOH  and use the glass stirring rod to transfer a drop of a solution to a spotting tile. Test it's pH using universal indicator.
3. Keep adding NaOH and test the solution by repeating step 2. As you get closer to neutral you may need to test the solution after every drop.
4. Pour the neutral solution into an evaporating basin and evaporate the water out of the solution using the equipment needed

Neutralization

• A chemical reaction occurs when a acid and a base is mixed. The base stops the effect of the acid. This reaction is called neutralization. This is because a neutral solution is made if you add the right amount of acid and base  

• The aim is to identify the neutralization's reaction
