| Necessary Materials:
- 1 blank sheet of paper (any size)
- 1 compass (or just a glas which you can use to draw a circle)
- 1 pencil
- 1 thick pen (favorite color)
 
 
Steps:
 
First part: Use a pencil and draw thin lines
 
Draw a circle in the middle of your paper with ~ 12 to 18 cm diameter.
 
Draw a vertical line through the middle of the Circle,
 
Draw a horizontal line through the arc to get 4 pieces.
 
Draw 2 more lines till you have 16 pieces with the same size (i.e. 8 lines)
 
Label the intersections of lines and the circle from 1 to 16.
 
Second Part: Use a pen of your favorite color
 
Let x = 0.
 
Draw a line from the middle point to point 1 + x.
 
Draw a line from point 1 + x to point 2+ x.
 
Draw a line from point 2 + x to the middle.
 
If  x is smaller than 13, add 2 to x and repeat the last three steps.
 
If x is bigger than 13, draw a line from the mid point to a any corner of your sheet.
 
 
 
<br>Unfortunately Manuel was a very strict HGP so when he got in next-to-last line he repeated the last three steps and stopped. Maybe I should be more precise next time ;)<br>

• Take 4 of the 8 given acrylic colors.
• Give them a ranking in your personal favor from 1 (least liked) to 4 (most liked)
• Mix the colors with water and fill the syringes with them by multiplying the number you gave them multiplied by 0.2 ml (e.g.: most liked color => 0.8ml)
• Execution: Read the following steps in advance:
◦ Repeat the following substeps for all 4 colors:
◦ Start spinning the circle and start the stopwatch
◦ While the circle is spinning, spray the color  on top of it
◦ When the circle stops spinning, stop the stopwatch and note the time
• Multiply all measured times by 100 (to get rid off the decimals)  
• Open the website https://dejure.org/ and search for the results of the last step
• Take the word that describes the topic off the paragraph in the best way
• Write the number off the paragraph and the word in the middle off the „circles“ that you produced with your spinning top.<br><br>

- 1 blank sheet of paper (any size) - 1 compass (or just a glas which you can use to draw a circle) - 1 pencil - 1 thick pen (favorite color)


Steps:

Draw a circle in the middle of your paper with ~ 12 to 18 cm diameter.

Draw a vertical line through the middle of the Circle,

Draw a horizontal line through the arc to get 4 pieces.

Draw 2 more lines till you have 16 pieces with the same size (i.e. 8 lines)

Label the intersections of lines and the circle from 1 to 16.

Second Part: Use a pen of your favorite color

Let x = 0.

Draw a line from the middle point to point 1 + x.
