Teacher Instructions
for
Discovery Guide to
Hall of Ancient Life
for grades 3 through 5
Before Your Visit:
• This activity was developed by the Education Department to help your
students focus on learning while at the museum.
• Please make copies of this activity and bring it with you to the museum. The museum does not provide copies for your students.
• Please remind your students to use pencil, not pen, when completing
this Discovery Guide. Encourage your students to fold this guide in
half so it will be easier to write on. Students should not place their
papers on exhibit walls, cases, or labels, as this can damage them.
• Save paper! Print pages 2-3, and copy them one to two-sided, so that
you have a one piece of paper with questions on both sides.
While at the Museum:
• These questions will encourage students to look closely at museum
exhibits, think critically about what they are seeing, and discuss their
findings with their classmates and chaperones.
• Most of the questions can be answered by reading the labels, but there
are several thought and open-ended questions, and students are encouraged to give an original answer.
• Students may not always come up with the “right” answer, so if this activity is to be used for a graded assignment, we suggest that you grade
more on participation and thoughtfulness than accuracy.
• Volunteers are frequently available in the galleries to answer questions.
Other Information:
• This is one of three Discovery Guides for this grade range. Discovery
Guides are available for three galleries, including the Halls of Ancient
Life, People of Oklahoma, and Natural Wonders.
• Have questions or suggestions? Send us your feedback at education@
snomnh.ou.edu, or Education Department, Sam Noble Oklahoma Museum of Natural History, 2401 Chautauqua Ave., Norman, OK, 73072.
