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

Digestive System

 

Digestive System Organs

How the Digestive System Organs work.

Facts about the Small Intestine: 

The small intestine is about three times the length of your body — the longest part of the digestive tract. When you eat food, it's held in your small intestine for up to four hours because your body absorbs 90 percent of our nutrients through the small intestine, into your blood and this takes time. 

Facts about the Large Intestine:

The large intestine is important because it absorbs the water from food, to use it. If this did not happen we would dehydrate. 

Facts about the Stomach:

The stomach breaks down the food so that the nutrients can be used to make energy. 

Facts about the Oesophagus:

The esophagus takes the chewed food and takes it to the stomach.

Pite Pocket 

this Tuesday in my cooking class we made Pite pockets here is a photo and the ingredients we used:

1. Pita bread 
2. Onion 
3. Carrots
4. Tomato
5. Cheese
6. Lettuce
7. Sweet chilli sauce

man, my pite pocket was yummy all of the vegetables in there and the cheese and sweet chilli sauce um.

Photography

In Art class, we made photo montage. first we lookit Hannah Hoch. she is a German artist she borrows and recombines image and text to make photo manage to support women
