Why did we do this experiment? What science ideas were we investigating?
We were investigating the invisible forces that took part in this experiment.
The forces that took part were gravity and air resistance
Include the link to your planning + any other research you did about what makes a good parachute. Why did you choose to design your parachute how you did?
We decided to choose a traditional design; a parachute. Just like a real parachute the plastic bag captured the air, and slowed down the fall of the egg in the cup.
Results: Did your egg break?
No, our egg did not break. Although it cracked a teeny tiny bit the egg was healthy overall. It also fell the 2nd slowest, with 1s 240ms.
- Why did some of the parachutes fall faster than others? Link this to the formula for forces (F = ma)
Some of the parachutes fell faster than others because some had little to no air resistance catchers like parachutes. Some designs were flat and heavy, causing the egg to fall quickly and break.
- Were the forces balanced or unbalanced when your egg was falling? Link this to air resistance and weight.
The forces were unbalanced. There was a great number of gravity than air resistance. Why do we know this? Well, the parachute was going down, so obviously it was unbalanced. The weight also pulled the parachute more down.
How would you improve your design next time? Why would you do this? Reflect on how your experiment went.
Personally I would want to make the parachute more bigger, so that the air resistance will catch on the parachute MORE, making the fall slower and reducing the risk of the egg breaking.
