Height and feet Measuring

The feet can measure the height.


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.  2 Rulers
  2. 1 Meter Rulers
  3. A person
  4. Wall
  5.  A foot

Steps:

  1.  Get your rulers 
  2.  Get a person that can measure you
  3.  Take out your shoes 
  4. Measure yourself
  5. Then finally check how tall you are. 

Findings:

Foot  (cm)
Height (cm)
Lars22.5cm151cm
Axle26cm160cm
Vann25.4163cm

Lars:14.9 cm

Axle: 1.62 cm

Vann:15.5 cm

Material:



A pen / pencil
Tracing Paper
Writing paper
A ruler


Steps:

A. Top Of Letter Analysis

1. Sign your name on a sheet of writing paper and get someone else to try to copy it.
2. Place the tracing paper over both signatures and make a dot at the top point of each letter – for both signatures.
3. Join up the dots for both signatures to get two zigzag lines across the signatures. Are the lines the same?

B. Bottom of Letter Analysis

1. Put some fresh tracing paper over both signatures.
2. Put a dot at the bottom of each letter.
3. Join up the dots to make zig zag lines. Are the lines the same?

C. Slant Analysis

1. Put a fresh piece of tracing paper over both signatures.
2. Mark a vertical line down through the middle of each letter (using a ruler), slanting it in the same direction as
the letter.
3. Compare the set of lines for both signatures. 
What do they tell you.

Findings:



You
Friend
Top Letter Analysis
Are the lines the same?

My friend line is almost the same as me.
Bottom Letter Analysis
Are the lines the same?

Almost but the line is bigger.
Slant Analysis
What are the slants telling you?

It is telling me that me and my friend handwriting is almost the same.

Stop Motion

On art we have been doing stop motion, Stop motion is fun when you finish it. When I first started art I was so nervous because I did not know what to do. The only thing that I know was made clay people and that's about it. I was frightened because I thought that we will not finish our art project.

The next day my group decided to make a stop motion about football. Why football you ask? Because last time when we were at primary school we really like playing football, so that's why we decided to make a stop motion about it.
At first stop motion for me was scary because I don't know what to do. But then after a few weeks, I started liking art.
