feet in running shoes on leafy trailHealth is a Big Idea that impacts everyone. It cuts across science, history, policy, habits, age, gender, culture and geography. As a source for a challenge, health can be contextualized and made meaningful in almost every situation and involve all academic disciplines.

Using the research findings from your Investigations develop a synthesis that demonstrates a clear understanding of the challenge


Solution Prototypes – Using your research synthesis create multiple ideas for solutions and review each one to make sure your research supports it. Share the prototypes with various stakeholders and get feedback.

Solution – with the feedback from the stakeholders develop one solution that has the most potential for success.

Implement – Develop a plan to implement the solution with the stakeholders and collect data about the impact.

Evaluate – Using quantitative and qualitative measures determine if the solution is valid and what can be improved.


Throughout the experience take time to document the events and reflect on what is happening to build on prior knowledge and identify future questions.

Share what you learned with your local community and the world. Use #CBLWorld on social media.
