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: 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.

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.
