Project
This activity is meant to be an inquiry-based activity where students are given certain
parameters to build their rollercoasters. Students will be expected to discuss the features
that make their roller coaster successful or unsuccessful.
Materials: Foam Insulation Tubes (cut in half lengthwise to make two u-shaped channels),
masking tape, marbles, index cards
Students will build a roller coaster attached to the wall or coming out of the wall. The roller
coaster must have two hills, one loop, and must slow to a stop. Students must label on index
cards where the marble had its Greatest Potential Energy, Least Potential Energy, Greatest
Kinetic Energy, and Least Kinetic Energy. Students must also explain how friction plays a part
in their roller coaster design.

Design Squad – Design Challenges
http://pbskids.org/designsquad/
http://pbskids.org/designsquad/parentseducators/
The Design Squad Program is part of PBS Kids. This program is completely based around the
design process to help get kids excited about engineering.
The educational philosophy of Design Squad Nation is to:
Increase students’ knowledge of engineering and the design process
Improve the public image of engineering
Encourage further exploration
There are design challenges for many different concepts.
Electricity
Force/Energy
Sound/Music
Space/Transportation
Sports/Games
Structures
Technology/Materials
Students will enjoy practicing the Design Cycle, while constructing a product. There are
videos, demos, and reality TV episodes that go along with each activity.
Dissections
Dissections are a great way to reinforce information about body systems to students. They
are able to take place in a hands-on learning opportunity and enjoy seeing first hand what
the inside of various animals look like.
You can purchase the preserved specimens from Frey Scientific. Frey is considered to be a
CCS super vendor.
The following are labs that will aid in dissection.

Teacher Background
The force of GRAVITY is an attractive force between two objects. Here on Earth, gravity pulls objects downward
towards the center of the Earth.
The surface force counteracts the force of gravity by pushing up on objects. In water the upward surface force
is called the buoyant force.
Air resistance is the pushing force of air on objects. This force can push on a sail causing a sailboat to propel
itself forward, or air resistance can also slow a boat down by pushing against the sail, thereby opposing the
motion of the boat.
Water resistance is a form of friction in the water. Water resistance can be used to propel a boat forward (use of
oars) or water resistance can slow a boat down by pushing against the boat, opposing the motion of the boat.
For a boat to float, the downward force of gravity must balance the upward buoyant force.
An unbalanced force (wind, motor, oars) can cause a change in a boats speed or direction.
Speed is defined as the amount of distance traveled in a certain amount of time. Therefore Average Speed =
total distance/total time.
Teacher Notes
This activity is student centered and is recommended that each student build his or her own boat.
Engage (Warm-up)
1. Ask students to give descriptions of different types of boats.
2. Discuss the main components of a sailboat: Mast, Hull, Sail.
Explore and Explain (Instructional Strategies)
Day 1:
1. Show the united streaming video: Buoyancy and the Titanic [08:35]. Answer the two video questions on the
Physics of Boats worksheet.
2. Complete the force diagram on the Physics of Boats worksheet by drawing and labeling force arrows.
3. Introduce the project goals, limitations, and prototype design elements.
4. Students should begin to design and sketch their prototype design on the worksheet. (Provide books about
boats/internet access for students to use as resources.)
Days 2 and 3:
5. Provide the following materials for building: 4 in. x 4 in. x 2 in. styrofoam blocks, wood skewers, toothpicks,
popsicle sticks, paper, plastic bags, cutting tools, sandpaper, glue, tape, and anything else that would be
appropriate.
6. Students should build their boats no larger than 8 cm x 15 cm in order to fit into the gutter.
7. Students should keep the design elements/limitations as they build:
Limitations:
• Building Time = 2 class periods; Testing = 1 class period
• Size = no bigger than 8 cm across and 15 centimeters long
• Materials – Styrofoam, wood skewers, toothpicks, popsicle sticks, paper,
plastic bags, cutting tools, sandpaper, glue, tape.
Prototype Design Elements:
Boat Shape
Sail Placement
Sail size/shape/#
Total Mass
Ability to move in a straight line – Rudder
Forces - helping forces vs resistant forces
Weight dispersion/balance
Amount of Wind Energy (box fan)
Day 4:
8. Prepare the gutter(s) ahead of time. Place on a flat counter or tables, where the students have easy
access. Have several towels on hand.
Place measuring tape or meter sticks along the side of the gutters. Gutters are approximately 3 meters long.
Place reference points at the starting point (0 cm), 100 cm, 200 cm, and finish line (300 cm).

9. Students will work in partners to race their boats. One student will race his/her boat and hold the hand-held
fan, while the other student records the individual data on the Boats Afloat Race Labsheet. The teacher will
be the timer, so that there are no discrepancies. Each student needs individual data which includes the
time that the boat reaches each reference point.
10. Boats should be raced one at a time while the class watches and records the class data on the Boats
Afloat Race Labsheet. The class data includes the total distance and total time for each boat. Students will
calculate the average speed of each boat to see which boat had the greatest speed and rank them
according to which boat was the fastest.
Day 5:
11. Students will calculate their boat’s average speed at each reference point and create a graph showing
their boat’s change in speed over time based on their individual data.
12. Students will answer the post-lab questions on the Boats Afloat Data Analysis
sheet.
Extension/Expansion/Elaboration/Interdisciplinary Connections
1. As an extension, relate the change in speed over time to acceleration.
2. As an extension, discuss how this activity relates to Newton’s Laws of Motion
3. As an extension, allow students to remake/change their boat design and re- race, to see how the changes
affected the motion/speed of the boat.
4. Interdisciplinary connection: Math – Data Analysis
Essential Questions
1. What causes objects to sink or float?
2. What forces affect the motion and speed of a boat traveling through water?
Reteach Ideas
1. Use the Density Cubes from the CPO Textbook Toolkit. All cubes have the same volume (1g/cm3). Predict
and measure the masses of each density cube to show that objects/substances with equal volumes may
have different masses.
2. Place various objects in the water. Predict if they will sink or float.
Evaluation/Closure (Lesson Assessment)
1. Discuss post-lab questions.
2. If time, allow each student to show their boat design to the class and orally defend their boat design
choices.
3. Share other classes’ results and boat designs.

PHYSICS OF BOATS – Answer Key
United Streaming Video Clip: Buoyancy and the Titanic
1. Describe the forces that need to be balanced in order for a boat to float?
The downward force of gravity needs to be balanced by the upward force of the
_________________________________________________________________________
buoyant force in order for a boat to float.
_________________________________________________________________________
2. Why did the Titanic sink?
The Titanic hit a large iceberg causing a hole in its side. Water entered the
_______________________________________________________________________
lower chamber of the ship replacing the air. Water is more dense than air, causing
_________________________________________________________________________
the ship to become more dense. The downward force of gravity was stronger than
_________________________________________________________________________
the upward buoyant force on the ship. Thus, the Titanic sank.
