Students provided responses to a posttest questionnaire and interviews that focused on student outcomes (in this case, knowledge and understanding). Expectedly, various responses indicated more content knowledge around the key concepts taught compared with the pretest. There were responses that included understandings about a material engineer’s work and the purpose of a prototype with science understandings around the three states of matter and freezing/boiling points of water. Mathematics understandings were indicated around naming the properties of 3D shapes and recording temperature. Importantly, students connected their understanding of the property of materials with choices for the design task represented by comments such as: “gave us an idea of what was the best material to use” and being involved in an engineering activity: “gave me the logic I needed to work out the results”. Content knowledge about the properties of materials may have been formed as a result of the Medical Mission activity outlined in the student booklet.
