Model Atom blog

 aim: to make a model atom

method:

1. choose an atom to make (one between hydrogen and neon)
2. work out how many protons, neutrons and electrons it has.
3. assign protons and neutrons to a particular colour bead.
4. get a ball of blue tac and stick the protons and neutrons to this to make your nucleus.
5. cut out the appropriate electron shells and draw on the electrons with vivid.
6. connect the nucleus and electron shells with a piece of string
7. create a label to go above the model so people know what you have created.

results: i dont have hotspot so no photos for youuuuuuuuuuuuu

discussion:(explain what you made)

• atomic number is 2,mass number is 4
• protons is 2,neutrons is 2,electrons is 2
• electron arrangement is 2 in the first ring
• 2 facts about your atom 

-helium is a chemical element with a symbol 

-helium is the most common element 

• did it work? i guess so
• what would you do differently? not use heaps of blue tac

Article

State- this is about the power of failure.

Explain- it is about the learning from your failures. learning about your resilience. "It was pretty shit" Akira Ione said his life was 

Then his dad kick started his fight back.

my opinion- I think it was a good example of working to achieve your goals.

EOTC reflection

what was the best part in your opinion? why did you enjoy it?

My favourite part of the EOTC days out was going to jellie park. I enjoyed it because everyone was happy & having fun. And it was also my favourite part because everyone was getting along & going down the waterslide together, even when me & 7 other people went down and got told off at the end of the water slide.

was there something that challenged you?

yessssssssss. The a. forest was most challenging since im scared of heights, but it was also really fun because everyone was making me laugh, even when i didnt want to laugh.

if we were doing the EOTC days again, what other activity would you like to try?

I think i would like to goto the beach, because when when we went to spencer park we didnt get togo to waikuku beach. 

tell us 1-2 things you learned from one of the locations we visited?

1. not todo high ropes again

2. not let miss taylor take photos again

distillation

 last lesson we learnt that the process of evaporation is when a liquid turns into a gas. so we can separate a solution, by evaporating away the solvent to leave a solute (solid).

but what if we want to collect gas?? when we trap gas and turn it back into liquid this is called condensation.

what is?

-evaporation: heating a liquid, turns to a gas.

-condensation: cooling down a gas, turn into a liquid 

separating a mixture using distillation 

 aim: to separate a solute from a solvent in a solution using distillattion.

equipment: a solution saltwater,conical flask,heatproof mat,a delivery tube and bung, bunsen burner,tripod,gauze mat,retort stand,boss head and clamp,boiling tube

method: 1.set up the equipment as shown in the diagram

               2.add approximatley 50 ml of saltwater to conical flask.

               3.light your bunsen burner, open the air hole and gently push the bunsen burner under the tripod.

               4.heat the solution until most the solvent has been evaportated. turn off your bunsen burner.

observation: when watching the coke in the conical flask boiling and bubbles you can see less of the coke, and in the other tube there is a non-colour liquid. 

conclusion:

coke zero: had less dissolved substances 

coke: lots of dissolved sugar that was left in the end

Serial Dilution

 aim: do a serial dilution 

hypothisis: 

1.plave the 6 test tubes in a text tube racl. label the rack with numbers 1-6

2.using the measuring cylinder, fill text tube 1 with 10 ml of water. fill the remaining test tubes with 5 ml of water

3. using tweezers, add a single crystal of potassium permanganate to test tube 1

4. gently shake the test tube until the crystal has dissolved

5. using the transfer pipette,carefully remove exactly 5 ml from the test tube 1 and pour it into test tube 2

6.  rinse the transfer pipette thoroughly to ensure that no purple solution remains.

7. gently shake test tube 2 and repeat the transfer process, transferring exactly 5ml of solution from test tube 2 to test tube 3

8. rinse the pipette again and repeat the transfer process for test tube 4, 5 and 6

steak sandwich

 steak sandwich

Ingredients:

steak

bread

butter

salt

method:

first we got everything ready and started cooking the steak, when the steak was ready you butter and put whatever you want on your bread then add your cooked steak. then it was done because it didn't take long.

sight: i guess it looked alright 

smell: smelt like steak

tasted: like a steak sandwich

Rate: 8/10

What i would do differently to improve my score for the food: make more steak because it tasted like mayo more then actual steak

how did the team work together: good considering we had jayden in our group

filtration experiment

aim: to separate a solution from a precipitate (precipitate is the name for a solid that forms in liquid during a chemical reaction)

hypothesis:

method:

1.pour approximately 50mL of copper sulfate solution into a beaker.

2.add the same volume of sodium carbonate solution. a reaction will happen, you should see a cloudy blue precipitate form. called copper carbonate.

3.watch demo then fold filter paper inside of it, into the mouth a conical flask.

4.place the funnel with the filter paper inside of it,into the mouth of a conical flask.

5.stir the mixture in the beaker,then carefully pour it into the funnel.

6.observe what happend.

observations and discussion: it was blue liquid, then it went into a funnel with filter paper. and went all clumpy(blue solid) and then in the beaker under the funnel it was a clear liquid(the clear liquid is called filltrate) 

why the blue solid seperated from the liquid:

because it had large particles in it and the filter paper wouldnt let it through
