Assignment -
Task - Your task is to design a device that will safely protect an egg when dropped from a height of 5.0 m. Your egg should be contained inside of a plastic bag to minimize mess in the event of a crash landing.
Testing - You will need to conduct tests in attempts for your egg to withstand a drop in which it lands:
- Upright
- On its side
- On an angle (simulating a hill side landing)
- Rolling down a set of stairs
Parameters - You are not allowed to attach a parachute or floating device to your egg larder (for example helium balloons). Special consideration will be given to students who are able to safely land their egg using a machine with minimal mass. The more visible your egg is during landing will also be a considerable factor in the evaluation of your device. Your egg larder must not exceed a box 30 cm x 30 cm x 30 cm in dimensions.
Required Steps -
- Brainstorm the design of your egg lender and communicate with your teacher if clarification is needed.
- Create a blueprint of your design.
Note: straight lines should be drawn using a ruler.
Create a materials list of items you will be using build your Iander. Remember, budget wisely. Items found at home are recommended and points will be awarded for using common household items only.
Collect all materials and begin building your lander. Keep a log of any difficulties you encounter throughout the process and photograph the construction at different points.
Analysis - Answer the following in your analysis:
- Create a free body diagram of your egg lander in flight and determine the net force acting on your device.
- If you were to test your egg lander form a height of 100 m on earth, at what speed would your lander strike the ground?
- Suppose the speed found above is the maximum speed that you can safely land your egg at. If you were to attempt to land your egg on Mars where gravity is equal to 3.7 m/s2 from what height would you be able to drop the egg from?
- Explain how each of Newton's laws apply to your egg lander.
- What other factors must you take into consideration with regards to landing your egg safely in different places?
- If this were a real scenario where you had to build a device to safely land cargo on another planet why is it important to restrict the mass of the lander and the types of materials used?
- Evaluate the process as a whole. If you were to start over what would you do differently, the same?
- Describe the Physics concepts that you had to take into consideration throughout this assignment.
Report - submit a report that includes the following in any format of your choice:
- Blueprint.
- Materials list.
- Design/construction log.
- Presentation/photos of the egg lander in action.
- Analysis section including an evaluation and potential improvements to the process.
Note - Scale digital blueprint completed Complete materials list of only household items. Minimal mass and size log is extremely detailed and evaluates areas of difficulty and success Images of process documenting greater than 5 revisions Free body diagram and calculations are complete with no errors Newton's Laws are correctly analyzed and safety considerations are tested and discussed Reasonably brainstorms factors and evaluates that would affect alternative landings and evaluates overall process.
