1 roll of scotch tape
container of water (put some blue food coloring in the water to make
it look like "the ocean"
What to do
Before the activity, group students into cooperative learning teams
of 3-5 students. Then give the students these directions: 1.Using one
sheet of typing paper and the tape, design a boat with your group. You
may try different designs using one sheet of paper, but your final design
must be made from only one sheet of paper. 2.Your boat must be able to
fit inside the testing container, hold as many pennies as possible, and
still float. 3.We will test each boat and determine how many pennies
each will hold. 4.You may not test any part of your boat in the water
until the actual testing begins. 5.Each group will display their boat
before the testing begins, give the name of their boat, explain their
design to the group, and estimate the number of pennies it will hold.
6.The winning boat will be the one that holds the most pennies and still
floats. 7.Have each group weigh the number of pennies their boat held.
8.Make a class data table that includes: group name, boat name, estimate
of pennies held, actual number of pennies held, weight of pennies held.
Create a class graph of the information. 9.Have students analyze their
designs and discuss: strengths and weakness of the design, changes that
should be made, how they would make better use of the materials, etc.
10.All of the information should be recorded in science journals.
EXTENSIONS: 1.Scale diagrams and dimensions - determine surface areas
of each boat. 2.Observe effects of different variables: saltwater vs.
freshwater, warm water vs. cold water, etc. 3.Discussion or Field trip
to port or boatyard to observe how designs of boat is based on use/function
