I’m too young to fry!

Egg DropDon’t crack up!

Why did the egg

go to school?


To get “egg-u-cated”!


Your task

To design and create a protection system to minimize gravitational potential energy transferred to your egg!


Gravity

Falling objects are pulled toward the earth by the force of gravity

The farther they fall, the faster they will be going when they stop.


Why did Humpty

Dumpty have a great fall?


To make up for a bad summer!


Question???

How can we minimize the transfer of

gravitational energy (and the force of impact)

to our egg???


Definitions

Gravitational Potential Energy

Inertia


There are two things you can do,

Slow your egg down

Distribute the force of impact


Materials available3 tissues

1 paper plate

1 coffee filter

3 soda straws

1 band-aid

1 meter of yarn

1 dixie cup

1 sheet of paper

5 paper clips

3 pipe cleaners

5 rubber bands

Elmer’s glue

1 file folder

1 dm scotch tape

1 egg


Procedure

Design your protection system

Diagram and label your system

Create your protection system

Prepare to drop your egg from a height of 5m. Record your success or failure.

Record data on 5 other systems


What did the eggs do when the light turned green?


They egg-celerated!


AnalysisDid your egg crack?

What was it about your system that helped your egg survive a fall of 5m?

If you could do this lab over, what would you change about your protection system and why?

What were the similarities and differences in the successful and unsuccessful designs?


Title: Egg Drop ChallengeQuestion:

Definitions:Gravitational Potential Energy –

Inertia –

Task: Design a protection system to minimize gravitational potential energy transferred to your egg. Prepare to drop your egg from heights of 1,3, and 5 m.

Materials:3 tissues 1 paper plate 1 Dixie cup3 soda straws 1 band-aid 1 dm scotch tape5 rubber bands 1 meter of yarn 1 coffee filter5 paper clips 3 pipe cleaners Elmer’s white glue1 sheet of paper 1 file folder 1 egg

Procedure/guidelines: o Students must only use materials on the list above, but you don’t have to use it all!o We must be able to place your egg into your system just prior to your drop.o Your system can be no larger than 1 foot square.o Name your egg or system, record name, description and mass of system on the data table on

the back of this sheet prior to your drop.o Gather data on 5 other systems and record.

Design: Diagram and label your system below.

Hypothesis: What about your system is going to protect your egg? Why is this system going to work?


Analysis: Use complete sentences.1. At what height did your egg crack?

2. What was it about your system that helped your egg make it to this height?

3. If you could do this lab over what would you change about your protection system and why?

4. Do you see any patterns in the data? Similarities or differences between the successful and unsuccessful designs?

Say “no” to scrambles!Save our shells!!!
