Lesson Overview
Lesson Title:
The Egg Crash

Teachers:
Mr. Gayle Ellison (Primary)

Brief Description:
In this activity we are studying the force needed to crack an egg in a student constructed vehicle. We want to build a vehicle that will protect the egg with the greatest amount of force before it cracks.

Topics Introduced:
Newton's laws of motion

Lesson Information
Learning Expectations:

The students will be constructing a vehicle to protect an egg from cracking


during a collison.  The idea is to have the lightest weight vechicle that will


protect the egg from the greatest force.  We will use Newton's laws to


study  the collision and the forces involved.


Plan Of Action:

The students will be given introductory materials of Newton's laws of motion in student
handouts.
The students will be constructing a vehicle to protect an egg from cracking during a side
collision.
Before doing the testing and construction, the students will watch the DVD's:
1.  Understanding Car Crashes:  It's basic physics  by the Insurance Institute For Highway
Safety,  1005  N  Glebe Rd, Arlington, VA 22201,  www.highwaysafety.org
2.  Flight Testing Newton's Laws:  The Test Pilot Approach to High School Physics  by
NASA,  EC-2003-02-001-DFRC
a video of a crash at UNL testing site from the computer at

materials from www.iihs.org/videos/teachers_guide.pdf   Understanding Car Crashes.  It's
Basic Physics!  from the Insurance Institute for Highway Safety
We will also use other Google sites  by typing in SAFER barrier
 

Data Set Used:

Data will be collected from a lab on testing an egg during a collision.  We will use Newton's


laws to study the results and the forces involved in the collisions.


Materials Needed:

Egg Crash Activity Materials:


    bubble wrap (amount will be supplied by the teacher),  calculator,


dowel rod, dynamics cart, or some other rolling device to hold masses for


hitting the egg vehicle, eggs, electronic balance, or a metric scale, glue,


meter stick, metric masses (various sizes), plastic bag to hold the egg


in the vehicle, ramp to hold student vehicle and for rolling dynamics cart


down for a collision, stop watches, tape, tongue depressors, tooth picks,


wheels, and wood splints


Preparation Period:

There will be one lab period to test the vehicles and collect data from the


collisions.  The students may use lab time to construct their vehicle, or


build their vehicles at home before the final testing in lab.  Once the


data has been collected in lab, the students will have a couple of days to


complete the math and final lab reports.


Implementation Period:

This activity will be done a conjunction with our discussion of Newton's


laws of motion and forces.


Science, Math, Engineering and / or Technology Implications:

The students will study the forces in a collision.  They will see how the


design of the vehicle will provide different amounts of protection in a


collision.


Unexpected Results:

The students will discuss how the shape, materials used, type of glue used


and other construction factors affect how an egg is protected.  This relates


to the design of cars and trucks and their safety on the highway.


Considerations for Diversity in Education:

Students have their own ideas on how to build a vehicle to protect an egg.


They need to decide what materials will be used in their vehicle.


They need to decide on a shape for the vehicle to protect the egg.


They need to decide if one type of glue is better than another.
