Bell Ringer:

Can anyone tell me what is shown in the picture below? (I will recieve various guesses from students, hoping that at least one student will see that they are broken eggshells)

 

Right, these are broken eggshells. Can we now discuss ways in which eggs breakand how delicate they are?

(Students will respond by saying they break if they are dropped, thrown, etc. I will also hear stories of times that they were around when an egg broke.)

 

We are now going to discuss how eggs may be shipped so that they are not cracked or broken during shipping. We know that noone would buy a carton of craked eggs.

 

Objectives:

Students will become aware of many packaging materials and how some are more adequate than others. They will also apply this process in our experiment after showing imovie. (I may hear of times when students eggs were broken on the way home from the store or maybe how they had recieved something in the mail that was broken because of poor packing.)

 

Input:

Students will design containers using packaging materials that we discuss. We will discuss using newspapers, plastic, cotton, packaging bubbles, tissues, and anything else that the students can come up with.

(Students will be creative in coming up with their own ideas that were not discussed in class. They may construct their own packages at home.

Closure:

We will watch imovie to introduce the experiment that we are about to do. We will then perform our own experiment using the packing ideas that the students have come up with. They will each place an egg in their package and drop it from a window. I will tell the class that the students whose eggs do not break will receive a reward. We will then discuss why those eggs that broke did just that.

(Students will be enthusiastic toward the experiment and eager to see if their eggs made it through the drop.)
