To determine the best strategies for geoscience communication on TikTok, we created a TikTok account called Terra Explore. We produced 48 educational geoscience videos and evaluated each video’s performance. Our most-viewed videos received nearly all of their views from TikTok’s algorithmic recommendation feed, and the videos that received the most views were related to a recent newsworthy event (e.g., earthquake) or explained the geology of a recognizable area.

Many projects in their reporting phase are required to provide a clear plan for evaluating the results of those efforts aimed at translating scientific results to a broader audience. This paper illustrates methodologies and strategies used in the framework of a European research project to assess the impact of knowledge transfer activities, both quantitatively and qualitatively, and provides recommendations and hints for developing a useful impact plan for scientific projects.

We present the Magnetic to the Core project, which communicated palaeomagnetism to members of the general public through hands-on experiments. The impact of the project was tested with an interactive quiz, which shows that this outreach event was successful in impacting visitors’ learning. We hope our Magnetic to the Core project can serve as an inspiration for other Earth science laboratories looking to engage a wide audience and measure the success and impact of their outreach activities.

Our study is concerned with how the uncertainty in spatial information about environmental variables can be communicated to stakeholders who must use this information to make decisions. We tested five methods for communicating the uncertainty in spatial predictions by eliciting the opinions of end-users about the usefulness of the methods. End-users preferred methods based on the probability that concentrations are below or above a nutritionally significant threshold.

The UK Met Office ran an online game to highlight the best methods of communicating uncertainty in their online forecasts and to widen engagement in probabilistic weather forecasting. The game used a randomized design to test different methods of presenting uncertainty and to enable participants to experience being lucky or unlucky when the most likely scenario did not occur. Over 8000 people played the game; we found players made better decisions when provided with forecast uncertainty.
