UBD
Understanding By Design Model Lesson
Developed by: Lynn
Glover
Unit Summary:
The
community of Britton will have a new swimming pool in the spring of 2003.
The second phase of the project is to install a waterslide for one area
of the pool. The role of the 5th
grade Science class is to create a model waterslide for the pool.
Teams of students will build a model slide, write an abstract about the
slide, and present the team project in the form of a Power Point to the Britton
Pool Committee.
Enduring Understandings:
Students will understand that physical
laws of motion govern our world.
Essential Questions:
1.
How do the laws of motion affect our daily lives on earth?
2.
What variables can you manipulate to affect the movement of objects?
Knowledge and Skills:
1.
Every object in the universe has mass and therefore gives rise to a
gravitational force on every other object.
2.
Identify forces in specific situations that require objects to interact,
change direction or stop.
3.
Speed is a measurement of how far something travels in a certain time.
4.
Apply the formula for speed S=d/t to determine speed of objects.
5.
Velocity is a description of both speed and direction.
6.
Inertia is the tendency of an object to stay at rest or in a motion until
a force acts on it.
Performance Tasks, Projects:
(EQ = Essential
Questions; K&S = Knowledge and
Skills)
EQ 1:
The community of Britton will have a new swimming pool in the spring of
2003. The 2nd phase of
the project will add a waterslide to the pool.
Students
will interpret the laws of motion in order to apply them to the design of their
project – the waterslide.
Students
will journal how “my day” is affected by the laws of motion.
EQ 2:
While creating a design, students will demonstrate their ability to
manipulate the variables.
They will have
a conferencing day with Principal and high school physics students.

“SPEEDING
MARBLE” LAB EXPERIMENT
Materials:
wooden board, 3 books of equal thickness, meter stick, piece of masking
tape, marble, clock with second hand, Handheld
Procedure:
v
Place 1 book
on an uncarpeted floor and lean the wooden board against the book to form a
ramp.
v
Use the meter
stick to measure 300 cm from the top of the board to a spot on the floor in line
with the ramp. Mark this spot with
a piece of tape.
v
Hold the
marble at the top of the ramp and then release the marble and begin timing.
Stop timing when it passes the piece of tape.
v
Using the
handheld, calculate the average speed of the marble in centimeters per second by
dividing 300 cm by the number of seconds you timed.
v
Record your
data on the handheld in the Sheet Togo Application.
v
Repeat the
procedure 3 times.
v
Find the
average speed of the marble.
v
Repeat the
procedure using a ramp made with a stack of 2 books, and then 3 books, repeating
3 times and then finding the average.
v
Record your
data in “Sheet Togo”. When you
Hot Sync, you will be able to create a graph to include with your paragraph
answering the following question: How
did the average speed of the marble change as the angle of the ramp changed? Why?
Investigate:
How
might changing the amount of friction affect the speed of the marble?
Develop a plan to answer that question and try it.
Create a graph of your results.
When you set your spreadsheet up, follow
the same format as the spreadsheet below. Your
data will be different than this made up data.
Use the same headings in row 1.
You will use
the same headings in Column A and Column G.
Do the experiment and record you data.
Make a chart to display your data. Make
a copy to include with your paragraph.

CONSTRUCTION SECTION –SWIMMING POOL
Part 1 General
B. The Great Lakes-Upper
Mississippi River Board of State Sanitary Engineers’ “Recommended Standards
for Swimming Pool Design and Operation,” 1982 edition shall be used. Supplemental Standards shall include the “American National
Standard for Public Swimming Pools,” ANSI/NSPI 1991.
2.20
WATER FLUME SLIDE FEATURE ALTERNATE BID #1)
B.
Flume Slide length shall be measured based on the centerline of the
flume. Flume length to be
150’0”. The flume slide will be
designed and constructed for removal of the final 10-feet of the slide to
accommodate swim meet activities. Removal
of slide portion shall be easily accomplished with standard tools and no more
than two persons required for removal. No
jacks, hoists, or other special equipment shall be required for removal.
G.
The fiberglass flume dimensions will be a minimum of 36” width inside
barrel and a minimum depth of 22” on all straights.
Outside to outside of sections shall be a nominal 48”.
All curves shall be 225-degree profile design.
18.4.2 Flumes
18.4.2.1
Position
– A flume shall be perpendicular to the plunge pool wall for a distance of at
least 10 feet (3 m) from the exit end of the flume.
18.4.2.2
Clearances
– The distance between the side of a flume terminus and a plunge pool side
wall shall be at least 4 feet (1.2 m). The
distance between sides of adjacent flume terminuses shall be at least 6 feet
(1.8 m). The distance between a
flume exit end and the opposite side of the plunge pool, excluding steps, shall
be at least 20 feet (6.1 m).
18.4.2.3
Elevation
– A flume shall terminate at a depth between 6 inches (15 cm) below the plunge
pool operating water surface level and 2 inches (5 cm) above the water surface
level. The flume shall not exceed a
one-in-ten slope for a distance of at least 10 feet (3.0 m) from its exit end.
18.4.2.4
Design
– The design of the flume shall minimize abrupt contact with the slide and
prevent people from being airborne.
