My STEM Workbook 2 - Understanding Science, Technology, Engineering and Mathematics through design-process activities. The trilogy of My STEM Workbooks, Years 1-6, is a collection of project-based learning (PBL) activities for primary students. The PBL activities focus on eight United Nations Sustainable Development Goals. Zero Hunger (Goal 2) Good Health and Well Being (Goal 3) Clean Water and Sanitation (Goal 5) Affordable and Clean Energy (Goal 7) Sustainable Cities and Communities (Goal 11) Climate Action (Goal 13) Life Below Water (Goal 14) Life on Land (Goal 15) Students apply their knowledge and skills of Science, Technologies, Engineering and Mathematics to propose solutions to contextually appropriate real-world challenges. ¿¿¿¿¿¿The STEM PBL framework '1' was used to design the activities. Students need to tackle each challenge through the following steps: Ask ¿ Imagine ¿ Plan ¿ Create ¿ Improve [1. Forbes, A., Chandra, V., Pfeiffer, L., & Sheffield, R. (2021). STEM education in the primary school: a teacher's toolkit. Cambridge University] Press. Through these steps students apply their design-thinking skills to propose solutions to real-world challenges. Workplace Health and Safety is an integral part of each activity. Students are expected to handle tools, equipment and materials with care. Teachers are also expected to reinforce the use of safety gear - that is, Personal Protective Equipment (PPE) - as needed.
