# Cardboard Boat

Overview / Description:

Students will collaboratively design and construct a cardboard boat which will float and hold one human in the school pool using a variety of tools and methods.

Learning goals/objectives:

After completing this activity, students should be able to . . .

• Gain knowledge in using a variety of tools and methods to accomplish the goal of making a cardboard boat that floats and holds a student using basic geometric construction principles.
• Work collaboratively to plan, build, and problem solve.

Content Standards:

Math Geometry Standard:

Making Geometric Constructions:

G-­‐CO.12. Make  formal  geometric  constructions  with  a  variety  of  tools  and  methods  (compass  and   straightedge,  string,  reflective  devices,  paper  folding,  dynamic  geometric  software,  etc.).  Copying  a   segment;  copying  an  angle;  bisecting  a  segment;  bisecting  an  angle;  constructing  perpendicular   lines,  including  the  perpendicular  bisector  of  a  line.

Wisconsin Standards for English Language Arts

Listening and Speaking:

EE.SL.11-12.1 Engage in collaborative discussions. a. Prepare for discussions by collecting information on the topic. b. Work with peers to set rules and goals for discussions. c. Ask and answer questions to verify or clarify own ideas and understandings during a discussion. d. Respond to agreements and disagreements in a discussion.

ASCA MINDSETS & BEHAVIORS Standards:

B-SS 6: Use effective collaboration and cooperation skills

B-LS 1: Demonstrate critical-thinking skills to make informed decisions

Materials:

Students will have to obtain their own cardboard by contacting local businesses (this is to work on communication and social skills as well as professionalism.)

Per Group of 2-4 students:

• 2 tubes of liquid nail
• 2 tubes of silicone
• 2 rolls of duct tape
• scissors or box cutter
• Boat Rubric
• student swim suits
• life jackets

Learning Activities:

Assessment

Student diagrams will be collected.  Teacher will evaluate through observation whether students are able to professionally and independently obtain cardboard.  Teacher will keep anecdotal notes on students ability to collaborate, use professional manners, and problem solve.  Teacher will observe whether students use critical thinking to problem solve.  Cardboard Boat Rubric

Wrap-Up:

Teacher and students discuss the results: which boats were a success and which ones were not, and why.

Discuss professionalism and what problems occurred in team planning and discussion and how issues were resolved.

Discussions will happen with small groups to intervene on usage of tools and mathematical computations that led to inadequate boat flotation.

Extension Activity (for intervention or enrichment):

Extension:  Students may devise a propulsion devise using any materials of their choice.

Intervention:  Students may use computers to assist in modeling of their boats if necessary.
