What is it? This is a complete, go-to unit of work designed to promote the development of practical and scientific inquiry skills at Key stage 3. Pupils are tasked at investigating the concentration of salt solution that will allow the efficient hydrogen production when water is electrolysed. The framework for this investigation is set within the global energy crisis and how science can be used to solve real-world problems. It includes, teachers notes, a student work booklet and a presentation to set the scene. The objective is to allow the pupils to work with others and apply the Scientific method to an investigation aligned with their curriculum. It is designed as a stand alone unit or it would work well with elements, compounds and mixtures. I developed these resources for KS3 because we are moving some of our assessments towards the assessment of practical skills rather than just written theory tests. each unit includes assessment criteria. **Student Workbook - Designed to encourage students to think critically and explore concepts and serves as a record of the investigation, guiding the pupils through each of the tasks. this can be completed and used for assessment for lower ability pupils and those that require support. For higher ability pupils, this can be used a framework and notes for generating their own scientific report. **Teacher’s Notes **- Includes background information, experimental setup, and safety tips. Saves time on preparation and helps you focus on teaching. Introductory Presentation - A simple yet informative presentation to introduce the topic. Covers the basics and designed to spark interest and form the foundation for questions Designed to develop Enhances Scientific Inquiry - It’s a great way to introduce students to scientific methods and experimental science. The content aligns well with the post-primary science curriculum. Pre-prepared materials mean less time planning and more time engaging with your students. Practical Learning Experience - Hands-on activities make learning more impactful and memorable. Relevant Topic -With a growing focus on sustainable energy, understanding hydrogen fuel is more relevant than ever. This unit is designed to make your life easier and to make science more accessible and interesting for your students. It’s a practical, no-nonsense resource made by a teacher, for teachers.
