Our elf arrived in style this year attached to a parachute. Unfortunately, the parachute got stuck on a plant, so he needed a replacement quickly.
This activity is a great festive STEM challenge and a fun elf idea.
Don't forget I also have 24 days of FREE elf ideas you can print and use, including a parachute activity!
You'll need
Gift wrap or brown paper
Scissors
Tape
Hole punch
Four equal lengths of string
Instructions
Cut a large square out of the gift wrap or brown paper and carefully use the hole punch to make a hole in each corner.
Thread a piece of string through each corner and tape it in place.
Tie the other end around the elf.
Hold the parachute high in the air and drop!
Which forces act on a parachute?
Two main forces act on a parachute. These are gravity and drag or air resistance. Gravity pulls the parachute down, but as it drops, it creates a drag force which pushes the parachute upwards, slowing the fall.
Once the drag force balances the pull of gravity, the parachute will fall at a steady speed ( terminal velocity ).
What is air resistance?
Air pushes back against an object moving through it. This force is called air resistance or drag.
The faster an object travels, the greater the drag as more air molecules are pushed out of the way as the object falls.
More investigation ideas
Experiment with different-sized parachutes. Try to make a parachute that falls quickly and one that falls more slowly.
The bigger the area of the parachute, the greater the amount of drag created as it falls and the slower it will drop.
More experiments about forces
Try one of my experiments you can make fly.
Make some easy paper spinners. These are also great for learning about gravity and air resistance.
A bottle rocket is another fun experiment for learning about forces.
