My PBL Project

MATERIALS

• • ruler

  • pencil/pen/Sharpie

  • cardboard stock or plastic

• box cutter/scissors

  • brass fasteners

  • tape (for emergencies)

  • objects related to the Golden Ratio

PROCEDURES

Part 1

• 1. Find a piece of cardboard stock or plastic

  2. Measure the side lengths using the ruler and draw the sides with measurements from the Fibonacci sequence.

  3. Find an object such as a phone or tablet and use this gauge to see if those objects were designed

Part 2

• 1. Cut cardboard into four pieces with lengths of consecutive numbers of the Fibonacci sequence. For example two pieces are 34 cm, one piece 21 cm, and one piece that is 13 cm.

  2. Attach the pieces of cardboard with brass fasteners.

  3. Find an object and use your newly mad gauge to see if it has the golden ratio!

SCIENTIFIC PRINCIPLE

We already said this whole project is on the golden ratio. I will be using numbers from the Fibonacci sequence to set measurements of the sides of the squares in the template. The Fibonacci sequence is very closely related to the Golden Ratio, as the ratio between two consecutive numbers in the Fibonacci sequence is very close to the Golden Ratio.
