Home chemistry 3.

Aim: To see which chemical 
the mix creates the most gas.

Hypothesis: (What do I think will happen) 
I think that the vinegar and baking soda will make the bigger balloon.


Materials:

1.  Vinegar ½ cup
2. baking soda 3 tsp 
3.  salt 3 tsp
4. soda water ½ cup
5. yeast 2 tsp
6.  sugar 1 tsp
7. x 3 bottles
8. x 3 ballons
9. funnel 

Steps:

1.  get your bottles and balloons
2.  get your ingredients
3.  add ingredients
4. watch 

Findings:

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)	Balloon 3 ( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)	14.7cm	8.6	12.8 cm
Bubbles	small amount	small amount	large amount

conclusion:

My hypothesis was correct that the baking soda and vinegar created the biggest balloon. It was really cool to see the baking soda go into the vinegar and fill up the ballon.

At the end of it, all the balloons were different coloured and they were all different sizes. The smallest was the salt and soda water was the smallest it is very interesting how different the size is. 

I learned that gas can fill a balloon. I also learnt that the largest balloon makes less amount of bubbles.

Home chemistry 2.

Aim: To separate colours by using the process of chromatography.

Definition: Chromatography is a method of separating out materials from a mixture.

Eg. blood, ink, drugs,

Scenario

A crime has been committed. The police have a signed cheque and a letter from the same crime scene but it seems like the handwriting is different. They have 3 suspects but not enough evidence. They need to know if the letter and the cheque were written by the same person.

How do they tell if the pens used for both of these pieces of evidence are the same?

Rainbow paper

Materials;

1. Cup

2. Felt pens

3.Chromatography paper

Process:

Step 1: Get Chromatography paper and a cup

Step 2: Draw line with pencil 1cm from the edge 

Step 3: Pick two colours (preferably dark)

Step 4: add water and watch

Conclusion: What have I learnt from this experiment?

I learnt that if you add felt to Chromatography paper with water it will go up. I also learnt that the colour will change colour as it goes. My group picked two colours green and dark blue. The dark blue turned purple then went blue. Then the green went green to blue. This was a really cool experiment and I want to do it again. But maybe in other colours. Maybe with lighter colours and see what happens.

Skittles

Aim: To separate colours from skittles by using the chromatography.

Materials;

1. skittles
2. petri dish
3. water


Process:

Step 1: get a petri dish
Step 2: get skittles 
Step 3: put skittles in petri dish
Step 4: add water to petri dish and watch.

Conclusion: What have I learnt from this experiment?
That if you add water to skittles it will get the colours out of it. The skittles loses its colour and goes white. I learnt that skittles taste disgusting if they are wet. Also, the water is disgusting. It was really fun. I would want to do this again cause of the skittles.

Animal creator

The Redhorsecat

Diet: Carnivorous

Deer, Rabbits, Hares, Raccoons, and Rodents.

Head: Cougar

After they finish eating, they may cover the leftovers with leaves to save them.

Body: Woolly Monkey

They have a lot of hair to keep warm in winter.

Legs: Red fox

An adult weight of 3 – 11 kilograms (6.5 – 24 pounds). Redhorsecat have strong legs which allow them to reach speeds of approximately 48 kilometres per hour (30 miles per hour), a great benefit to catching prey or escaping from predators.

Tail: Horse

Have narrow tails with a small tuft at the end - a fly swatter. Look at a horse's tail and you will see something quite different - a fountain of hair that appears to sprout right from the horse's.

Habit: Forest

I picked a forest because it’s a wild animal that loves nature.
