STEMulating Design Challenges in Science, Grades K–2
Suggested Time Frame
• Ask, Imagine, and Plan: Allow teams 1–1.5 hours which may be broken down over a few days. This should include time for students to
research bridges and bridge construction (not more than 45 minutes)
explore the materials (about 5 minutes)
sketch their bridges independently (about 10 minutes)
reach a team consensus on final bridge design (about 10–15 minutes)
• Create, Test, and Improve: Allow 45–60 minutes for teams to build,
test, and improve their bridges.
• Evaluate: 5–10 minutes for each team to test and present their bridge
to the class
The amount of time needed for this challenge may vary depending on your
students’ research skills and findings.
