Home Chemistry: Skittles, Color

Home chemistry: Skittles, Colors
Aim: To separate colors from skittles by using the chromatography.

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

Eg. blood, ink, drugs,

Materials

1. Petrie dish.
2. Water.
3. Skittle.

Process:

Step 1: Get the Petrie dish.
Step 2: Put All six skittle in the Petrie dish.
Step 3: Spread the skittles out evenly in the edge of the dish.
Step 4: Put some water inside the Petrie dish

Conclusion:

I learned in home chemistry that or how to make a water
rainbow made with only three materials which were
a Petrie dish, Water and skittles, well I could say that this
the experience was very fun and satisfying on how the skittles
color and the made the color spread it was Exciting.

Home chemistry: Crystalization

Aim: To learn about a saturated solution and how to make crystals
Definition of the 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.


Image result for borax crystals

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1) Shape pipes
2) Cups
3) Pegs
4) Steering stick
5) Sharpie

Process

Step 1: Shape pipe cleaners into a shape, 
Step 2: Hang shape on a peg, 
Step 3: Mate up borax solution, 
Step 4: Label your cup, 
Step 5: Take and put three teaspoons into the borax cup
Step 6: Steer the borax cup as soon as your teacher or when you feel might be the right time,

Sugar Crystals

Grow your own Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) Shape pipes
2) Cups
3) Pegs
4) Steering stick
5) Sharpie

Process

Step 1: Shape pipe cleaners into a shape, 
Step 2: Hang shape on a peg, 
Step 3: Mate up Sugar solution, 
Step 4: Label your cup, 
Step 5: Take and put three teaspoons into the sugar cup 
Step 6: Pour half a cup of water into the sugar cup & steer it,


Image result for how to make salt crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) Shape pipes
2) Cups
3) Pegs
4) Steer stick
5) Sharpie

Process

Step 1: Shape pipe cleaners into a shape, 
Step 2: Hang shape on a peg, 
Step 3: Mate up Salt solution, 
Step 4: Label your cup, 
Step 5: Take and put three teaspoons into the salt cup 
Step 6: Pour half a cup of water into the salt cup & steer it,

What crystals worked out best and why?:



Conclusion:

I and my group which was Aisa, Nature, Lasa, Ryan, and we did find out somethings, to begin with we found out how Sugar, Salt & Borax was made and how to make types of crystals with Sugar, Salt & Borax, Our exspirment worked best because I think what worked was because we might of steered it at the right time as we let it sit as the crystals grow?   

________________________________________________________________________




After watching the videos as a class, explain how the following crystals are formed:


Type
Explanation
Salt
One way of forming salt crystals is by the ocean, We can get this unprepared salt from the salty ocean and burn it in these special type of different machines to cause the salt to be prepared and ready,   


Sugar
You can make sugar by sugar canes so you can grow sugar canes to about 20ft and when you cut it at the bottom it is a surprisingly a fun fact but sugar can regrow if you cut it at the bottom, The cut sugar cane gets put into a ton of machines gets shredded apart and then evaporated so burnt and that makes sugar but there are other.  

Snowflakes
Snowflakes can be formed by the rain & the temperature below Zero and the vapor being or going up to the sky and the perfect timing sortive with the rain, Wind temperature below 0 and the vapor being together at the same time,

Home Chemistry: Forensics, Height, Measurements/ Term 2, Week 4



THE FEET CAN MEASURE THE HEIGHT

The bones of the feet can tell a lot about a person.
What do feet reveal about a person's height? Forensic
anthropologists team up with law enforcers to help solve crimes.
Bones of the feet can reveal an interesting fact about
an individual. Let's combine math with forensics to see how.

Image result for foot to height ratio chartImage result for foot chart size


Aim: To use forensic science techniques to measure
the height of a criminal.


Material:
  1. A Long Meter ruler,
  2. Yourself or...
  3. Someone else,
Steps:
  1. Get A Long meter ruler,
  2. Rule your height, Record your findings
  3. Rule off your shoe or foot… Record your findings.
Findings:
Name
Foot  (cm)
Height (cm)
Aisa
27cm
169cm
Niko
26cm
166cm
Ryan
22cm
152cm

Divide the length of each person's foot by his/her height. then multiply it by 100.
Conclusion:

Today for home chemistry I and my group have been working
on finding the height by your foot size. It is pretty cool finding out that
there is more than one way to solve a crime. It was pretty hard but I understood
it in the end.  This has been an awesome experience and I would love to do this again.
