The brand new series of Let's Find Out is on RTÉjr now, and for Science Week the crew are sharing some fun experiments to help answer some of Zoom's big questions.
Tune in to RTÉjr weekdays at 7am and 2.30pm or watch it any time on RTÉ Player!
In the video up topZoom wants to find out about falling and if there is anyway to stop an egg breaking when it falls. So John and Sophia show Zoom how to make a parachute for an egg…
YOU WILL NEED ADULT SUPERVISION FOR THIS!
You will need:
- A plastic bag or light piece of material
- Four straws
- String or wool
- A scissors - be extra careful!
- A small container to hold the egg
- Some bubble wrap or soft material
- An egg
- Sample egg parachute
What to do:
- Lay four straws out in a square shape and tape them together at the corners.
- Open out the bag (trim off any handles if necessary) and attach them to the straw square with tape.
- Cut four pieces of string to the same length (about 20 to 30 cm long).
- Tape one end of each string to one corner of the straw square and the other to one corner of the small container you are using as the basket for your egg.
- Once you have all four pieces of string attached simply line the basket with bubble wrap and something soft and bring your parachute and egg outside.
- With adult supervision, find a high place where you can stand safely to launch your parachute.
- When in place, throw your parachute up into the air and watch as it falls to the ground. Does the bag fill with air? Does it fall slower than you expected?
- Once the parachute reaches the ground, check the egg and see if it is undamaged!
The science bit
We can use air to slow down how fast a falling object is moving, in fact, that’s exactly what parachutes do. When an object falls DOWN, air pushes UP against it creating a force we call air resistance or drag.
This force slows down the falling object. With enough air resistance (like with a parachute), a falling egg can land safely on the ground, without being damaged.
