Aim:

To understand how flight forces work by building and testing a simple paper glider.

Requirements:

• Chart paper or light cardboard

• Scissors

• Tape

• Straw (drinking straw)

• Ruler

• Pencil

• Rubber band (optional, for launch)

Safety Note:

Use scissors carefully and fly your glider only in open areas (classroom corridor or playground).

Steps:

Step 1: Prepare the Paper Loops

• Cut two strips of chart paper:
  • One large strip: 2 cm × 15 cm

  • One small strip: 2 cm × 10 cm

• Roll each strip into a loop (ring) and tape the ends together.

Step 2: Attach Loops to the Straw

• Tape the large loop to one end of the straw (back).

• Tape the small loop to the other end (front).

• Make sure both loops are straight and balanced.

Step 3: Test the Glider

• Hold the straw in the middle and throw gently forward.

• Watch how far and how smoothly it flies.

Step 4: Observe & Experiment

Try changing:

• The size of the loops (bigger/smaller)

• The length of the straw

• The throwing angle

Note what happens:

• Does it glide longer?

• Does it fall quickly?

• Does it wobble or stay straight?

Observation Table

Explanation

• The large loop creates lift by pushing more air.

• The small loop reduces drag, helping it move forward smoothly.

The balance of loop sizes helps your glider stay stable — just like a drone balancing its propellers!
