sional display. Individual exhibits are limited in size
to 30” wide, 24” deep (front to back), and 36” high.
Club exhibits are limited in size to 60” wide, 24”
deep and 36” high. Posters are limited in size to
30” by 24”.
Exhibits may include pictures, models, diagrams and
actual articles if they meet the safety standards listed
below. Drawings or photos which are an essential
part of the display should be firmly attached to the
board. Loose materials like soil, bark or sand must
be displayed in closed containers. No books or note-
books will be accepted as part of the display. The
following materials will not be allowed on the dis-
play for safety reasons:
• Living organisms- plants or animals
• Any liquids
• Aerosol bottles or other pressurized gases
• Glass
• Hazardous substances
• Sharp items
Display (all parts) should be able to last the duration
of the fair in good repair. An Educational Display
Exhibit Card (000-01) must be attached to each exhib-
it. Judging criteria are outlined on the 4-H Science
Investigation Display Evaluation Sheet (840-100).
Both are available from the county Extension Office or
the state 4-H website at http://oregon.4h.oregon-
state.edu/contest-materials-science-engineering-tech-
nology
Club exhibits are to be entered under the club name
but must include the names of all members and lead-
ers. This may be on a separate paper securely at-
tached to the back of the exhibit. Club exhibit will re-
ceive one ribbon per exhibit.
Each piece of an exhibit must have name, county
and class numbers securely attached to it. All parts
of the display should be attached to one another in
some way to keep the exhibit together as a unit.
Single posters may be displayed by hanging or sta-
pling to the wall. All other displays should be free s-
tanding. All information contained in the exhibit must
be able to be viewed by the public by looking at the
display.
include the appropriate Project Description form filled
out neatly and securely attached to the exhibit. 4-H
Project Description sheets are posted at
http://oregon.4h.oregonstate.edu/contest-materials-
science-engineering-technology Participant should
answer the description page carefully and in full sen-
tences.
If more than one article is contained in the exhibit then
each article must be labeled with the member’s name,
county and class number and attached to each other.
The one exception to this is the Rocketry Engineering
Journal, which must be included with the Rocket dis-
play, but is not required to be attached to it. This may
be done with masking tape/index card with a marker
or writing directly on the back with a marker. Judging

on their project displays.
In some cases, the exhibit may be a poster or a three-
dimensional display. Individual exhibits are limited in
size to 30” wide, 24” deep (front to back), and 36”
high. Club exhibits are limited in size to 60” wide,
24” deep and 36” high.

Description: The purpose of this type of exhibit is for
members to communicate the processes and out-
comes of a scientific investigation they design and
conduct themselves. The display must include (1) a
question or hypothesis, (2) an investigative procedure
(What was done?), (2) the data collection or observa-
tion method (How was it collected/ observed), (3) a
report of the data collected or observations made, (4)
an analysis of the data collected or observations made
(How do you interpret the data and evidence?), (5) a
conclusion addressing the original question or hy-
pothesis (Does the evidence support or refute your
claim?). Intermediate and Senior Exhibits must in-
clude a data chart and a graph or other visual repre-
sentation of the data.

following numbers.

Description: An exhibit of a rocket made by the
member from the Aerospace Adventures Stage 2
project kits and a Rocketry Engineering Journal.
Rockets displayed in this class may only be made
from the Estes Gnome ™, Wizard ™, or Mosquito ™
rocket kits. Rockets included in a static display MUST
be shown without engines or igniters. All the parts of
the rocket and their function should be identified.
Rocket components which must be included and la-
beled are body tube, nose cone, engine hook, fins, re-
covery system (streamer or tumble method), launch
lug, engine mount, and shock cord. On the display,
list any items required to launch the rocket and their
function such as the launch system, igniters and re-
covery wadding. List the appropriate engine size(s)
for your rocket and your level of experience. The ex-
hibit will be judged on neatness of labels and work-
manship. See additional exhibit requirements, above,
for Technology classes. Evaluation: Use Aerospace-

clude a rocket launch and flight report. Rockets dis-
played in this class may only be made from the Estes
Monarch ™, Alpha™, or Alpha III™ rocket kits.
Rockets included in a static display MUST be shown

and their function should be identified. Rocket com-
ponents which must be included and labeled are body
tube, nose cone, engine hook, fins, recovery system
(parachute), launch lug, engine mount, and shock
cord. On the display, list any items required to launch
