Involving school students in authentic research beyond their school learning means creating participatory, out-of-school opportunities related to research processes, giving them a voice in the applied format of science engagement. Important for such endeavours is a group of people we identify as “enablers”. Based on insights from two long-term and large-scale science engagement initiatives in Germany (the Darwin Day science outreach and the Plastic Pirates citizen science program), we identified four principal work tasks of enablers. They are described as (i) aligning the needs, expectations and goals of involved participants, (ii) translating differing conceptions about science into shared visions, (iii) guiding the design of the initiative through educational theory, and (iv) evaluating the success of the out-of-school science engagement initiative. We further suggest that self-awareness of being an enabler, working at the interface of the research and education sphere, is an important prerequisite to successfully collaborate with participants.

The mitigation of the climate crisis demands effective communication strategies. Transforming food systems plays a key role in climate protection, not only by changing eating habits, but also by preventing food waste. While workplaces are commonly used for health promotion activities, they are a rare setting for science communication. This practice insight targets individual food waste reduction through a workshop at the workplace, including a lunch from rescued food, documentary screening, discussion, and expert presentation. It aimed to enhance participants’ self-efficacy and intention to reduce food waste. The effectiveness of the screening was tested experimentally by evaluating the effects of positive and negative framing. Exposure to negative framing was associated with higher intensity in negative affect, whereas positive framing appeared to be associated with higher self-efficacy. Furthermore, this practice insight provides strategies to foster science communication in workplaces.
