10 tongue depressors (or extra wide popsicle sticks)
10 popsicle sticks
10 paper clips
5 soda straws
5 rubber bands
3 pipe cleaners
2 feet of yarn
10 cotton balls
1 plastic sandwich bag (size small)
1 bottle of glue
Students do not have to use all of these materials, but they can't use anything not on the list. Below are a few pictures of "ships" that student's build for this week's drop.
Eggs were placed in the "ships" and we went to a nearby parking garage. We dropped from 2 feet, 6 feet, the 2nd floor, the 3rd floor, and the 4th floor, all onto grass. Out of 12 groups, 3 survived the 4th floor drop. These three then dropped their "ships" from the 4th floor onto rocks. The parking garage is only 4 stories high. Two of the groups survived the rock drop. The next step was to drop the "ships" upside down. Neither of the remaining groups' eggs survived, although in previous years I've had students build ships that survived the rock drop.
I'll point out that this is an activity that you can do with kids of any age. The younger the child, the more liberal you must be with the supplies. I've done this before with groups of 3rd, 4th, and 5th graders. We use the same supplies, but I give them more popsicle sticks and cotton balls to use. Even younger kids can do this if they have sufficient parental help. I haven't done this with my daughter yet, but it's on my list of sciency things to do.
