Crystals

Aim: To learn about a saturated solution and how to make crystals

Crystal video

Definition of solution: 

A liquid mixture, when something is dissolved into a liquid (eg: sugar in water) 

Definition of saturated: 

Having or holding as much as can be absorbed of something (when no more sugar or borax can be dissolved into the water)

In groups of three you will make three different types of crystals and compare the results.

Borax Crystals

Findings

Describe your crystals in the table below.

Extra Findings while mixing...

I found that when mixing it takes a little while to make the mixture but also when you leave it for a few secounds, and you scrape your stick along the bottom and bring your stick up it still has borax on it but then disolves again.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Round squared ball	Big and Small	Hard
Sugar	Square	Medium	Smooth
Salt	Cube

What crystals worked out best and why?: 

Conclusion: 

Type	Explanation
Salt	Salt is formed by an evaportation by salty water, like sea water. Enclosed bays are where you could find sea salt. In region places.
Sugar	Most green plants produce sugars, they create a form of sugar. If a plant makes more food than it requires, it stores it. The sugar is made from many green plants.
Snowflakes	A snowflake creates an ice crystal. Water Vapour freezes normal crystals, building new ones - A snowflake also has 6 arms, sometimes

Type	Number of sides	Picture	2 EXAMPLES
Monoclinic	3		Cube, Octahedron
Isometric	0		Cube, octahedron
Hexagonal	7		Dipyramid, Primsm, rhombohedron
Teragonal	0		Zircon, rutile
Orthorhombic	2		Sulfur, topaz
Triclinic			Albite, rhodonite

Drama - Fitness and Body

How does Fitness affect my body and mind?

It affects my body by knowing that I have done fitness by puffing after.It increase my heart rate. If you do fitness regularly your micules get stronger. You use more energy which means you also need to eat more and also it makes you sleep better. Fitness releases stress your mind, improves coordination.

What fitness am I doing at the moment?

I am currently doing...

Netball- Thursday practices, Friday winter sport, Saturday game
Walking, running, scootering, biking, and walking
I get to school in 12 mins from my house

What is my fitness goal?

My goal is to practice on Fridays for netball on Saturday.

How is my goal going?

It's going really well as I do it for winter sport!

Rocket Science.

Today we are learning about filtering dirty water. We are learning about filtering. Here are some ideas of filtering....

1. There's pool filtering
2. Filtering removes bad stuff
3. There's also cleaning filters and...
4. Internet Filters

Your probably wondering Internet filters?... There's no such thing well actually there is.... Do you know the Snapchat app? Well that has filters.

Materials

1. Filter Paper
2. Bottle
3. Scissors
4. Funnel
5. Sand
6. Stones small
7. Dirty water

Steps

1.  Get a bottle
2.  Cut it about the big line
3. Get a filter paper round
4. Make it into a cone
5. Add sand into it
6. Add pebbles on top of the sand
7. Pour dirty water on top
8. Count how many try trips per minute

Conclusion

The water that flowed through the filter was clear with a green tinge. The water flowed at 32 drops per minute. The bark,soil and leaves sat on top of the Peebles.

This experiment should turn out to be filtering water, which means the dirty water becomes clean water. This experiment is really easy to make, but I sujest you DON'T drink the water!!!! 

This experiment you can learn a lot about filtering as well. Here are some more ideas of what type of filters there are...

Water

Air

Oil

Kettle and 

Pool

It's your turn to try. Have a go!!

Paper Plane

As I have written it on paper here is the working and my better part of my conclusion is in the working. Read carefully

Ballon Bottle

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

Hypothesis: I think that when we add the baking soda and vinegar it will make the balloon inflate up.

Materials:

1.  Bottle and ballons
2.  Soda
3.  Salt
4.  Baking soda
5.  Vinegar
6.  Lemonade

Steps:

1.  Get 2 bottles
2.  Get 2 ballons
3.  You need to pour halve a cup of vinegar in 1 bottle and the other half a cup of lemonade 
4.  Add 3 teaspoons of baking soda in 1
5.  and the other 3 scoops of salt and it may suck in 
6.  Watch what happens

My images:

Findings:

That the 1 with salt does not inflate

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)
Balloon Size (cm)	14 cm	0cm
Bubbles (small, medium, large)	Small	None

Conclusion:

White Powders

Aim To learn about the makeup of different white powers.

There are a number of different white powders in our everyday life. Some of these are harmful and others not. Test the four white powders listed to see which one has been found at the airport.

Here are some examples of everyday kitchen white powders.
Flour, Cornflower, sugar, salt, baking soda, icing sugar, Tartaric acid, citric acid, gluten free flower

You will be given a small amount of 4 white powders on your car lard using a magnifying glass look at the powders.
Look at them under your magnifying glass and record what you see

These are the four powders we will be using. Upload a photo of each powder

1. Cornflower
2. Baking soda
3. Salt 
4. Sugar

Before you add the iodine, vinegar or water you will need to divide each powder into 3.

Materials

1.  Iodine
2.  Water
3.  Baking sda
4.  Sugar
5.  Salt
6. Cornflour
7. Pipette
8. Paper

Steps

1.  Fold cardboard into 4s
2.  Write, sugar, cornflower, salt and baking soda in each square
3.  Divide each into 3s
4.  Add Iodine to each 1
5. Add water to each 1
6. Add vinegar to each 1
7. And watch

Findings

Appearances.                Sugar.            Salt.              Baking Soda.         Cornflower 

Texture.                        Crystals.        Small            Tiny.                      Chunky

Smell.                           Nothing.       Nothing.        Nothing.                Nothing

Iodine.                          Colour.          Dissolves.      Hardens                Slides-harden

Water                            Melts.          Shiner            Nothing                  Slides-harden

Vinegar.                        Dissolves.     Shines.          Bubbles.                Slides-harden

Finding...

Whilst I was doing this experiment with my group we found a lot of things. We found out what the mystery powder was. Can you guess? IT WAS BAKING SODA. It was really easy finding out which was which as we did the vinegar and it made bubbles like the other one. We learnt a lot from this experiment as we never knew things but there was a lot of experimenting. How did your experiment go?
