NGSS Engineering Standards

MS-ETS1-1.

MS-ETS1-2.

MS-ETS1-3.

Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

HS-ETS1-2.

HS-ETS1-3.

Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.

Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.

Problem and Design

The purpose of the egg drop is to design a structure of some kind that will protect an egg from cracking as a result of falling from a pre-determined height. This height is typically a second-story window, but it can increase for additional challenge or for older students. The materials permissible in order to construct the structure can also vary dramatically, depending on the desired level of challenge. Everything in the materials list below is therefore optional, and any combination of the items can be utilized to tailor a unique experiment, which can therefore also be repeated throughout the year with different instructions.

Materials Needed (Any Combination)

Tissue Paper
Scissors
Rubber Bands
Plastic Bags (parachutes)
Plastic Containers
String/Yarn
Packing Peanuts
Bubble Wrap
Scrap Paper
Cardboard
Used Toiler Paper Rolls
Glue
Tape
Straws
Cotton Balls
Coffee Filters
Styrafoam Cups
Anything Found in the Recycling Bin

But certainly everyone will need EGGS!

Procedure

Decide whether students will work in groups or individually.
Determine what materials will be used.
Allow time for construction of the apparatus.
Once construction is complete, students will toss their eggs out the window, one at a time.
Have students find their eggs and assess their condition.
Have students whose eggs survived explain their design and thought process to the class.
Optional: Allow students to try a second time.
