Wananga

 today in class we got to do well-being time we get to do well-being time two times a week. So I picked to do basketball with my friends we only had 10 minutes to play but my teacher gave us 20 minutes and now that's why my teacher is the best teacher in the school. after 20 minutes we came back inside the class and we had to do some work now like we had to look at this new app for the school its called My Mahi its a pretty good app you can see your timetable, Assessment results, newsfeed, daily notices, and you can set up your goal for the year or term and yea much more. 

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 electrons 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 (picture)

-Discussion (explain what you made)

-Atomic + mass number

A3 M7

-Number of protons, electrons, neutrons, 

P3 E3 N4 

-Elections arrangement 

I had 2 on the inside 1 on the outside.   

-2 facts about your atom 

There are three parts to an atom. 

There are over 100 different kinds of atoms.

- Conclusion 

-Did it work? 

it kind of worked but after a day the atoms fell.

-what would you do differently?

next time I would use different sort of materials.  

  

Distillation

Filtrantion: Solid + Liquid 

Evaporation: Liquid (solid dissolved in Liquid) Solid 

Distillation: Liquid (solid dissolved in liquid) gas, liquid, solid.  

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 distillation.

Equipment: A solution of coke, 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 approximately 50 mL of coke to your 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 of the solvent has been evaporation. turn off your bunsen burner.

 Hypothesis:    

what do you think will happen when you heat the coke vs the coke zero.

Serial Dilution

today in chemistry we did a dilution experiment  first we had to get into a group of 4 to 5 then get our equipment the equipment was a potassium permanganate crystal, six large test tubes, tweezers, a plastic transfer pipette, a test tube rack, 10 mL measuring cylinder then we had to put the six test tubes in a test tube rack then we had to label the test tubes from 1-6 after labeling the test tubes we had to pour 5ml water in 5 of the test tubes and the 6th one you pour 10ml water after adding the water then we add a single crystal of potassium permangenate to test tube one gently shake the test tube until the crystal is dissolved   

Aim: to make a dilution serial to investigate 

Method: potassium permanganate 

Hypothesis:     

Filtration Experiment

today in Chemicals and chaos we did an experiment with two different substances. the two different substances are sodium carbonate and copper sulfate. The first steps were safety, so we had to put on some safety glasses then get the equipment for the experiment 

Solvent - thing doing the dissolving (Liquid)

Solute - thing being dissolved (Solid)

Solution - a mixture that is formed. 

Filtration - separates particles based on size.

Filtrate - liquid after it has been filtered.

Mixture - 2 or most substances together.

Solubility - the ability to dissolve.

- blue, transparent, liquid copper sulfate sodium carbonate.

- clear, transparent liquid.

looked like a blue opaque liquid clear liquid-solid, blue copper carbonate. 

the stuff- equipment we used 

sodium carbonate,

copper sulfate, 

conical flask,

stirring rod,

200ml beaker, 

funnel,

filter paper,

Nachos

A few weeks back we had to make nachos so first, we had to get all the ingredients for the nachos, so once we had got all our ingredients we had to start putting the things together. So we cut up all the vegetables like tomato, onion, etc so when we had cut up all the vegetables we started to cook our mince in vegetable oil. After it was well cooked we added the source and the vegetables, when it was done cooking the teacher gave everyone there own bowls of nacho chips and we had to add the mince that we had cooked into the chips and we also got put cheese on top and we ate the food.

Chemicals

Today we in Chemicals and Chaos, we are learning about particle theory and diffusion.

Particle theory is 6 rules about what particles do.

All matter is made up of particles

All particles in a pure substance are the same                       

There is space between all particles

Particles are always moving

There are attractive forces between particles

Temperature affects the speed at which particles move
