BrainPOP Junior’s official website, jr.brainpop.com, provides users access to its movies. The website’s homepage features a Movie of the Week section, where users can stream the available movie. All BrainPOP Jr. movies run between three to five minutes and introduce or review a certain educational topic.
Most movies feature a character named Annie who poses questions that appear in a notebook next to the video. This feature allows children to make connections and predictions. The website’s movies also provide closed captioning if needed. BrainPOP Jr. movies are also available on its official mobile app, which is available for iPhone and Android devices as of 2015.
