# Explore types, interactive video, branching scenarios and self-check > Build content to look through, a video with stops, a case where each choice leads somewhere, or a self-check. Most of these types share one way of working: a list of parts on the left, **What students see** in the middle, and the picked part's settings on the right. Add a part with the button under the list, such as **Add another section**. Everything saves a moment after each change. ## Explore: content to look through, not marked - **Accordion**: sections with a title that students select to open. Choose **One section open at a time** and whether **The first section starts open**. - **Image slider**: slides, each a picture with a **Caption**. - **Timeline**: events, each with **Its date** (any words, such as 1628 or The 1600s), **Its title** and an optional picture. - **Image hotspots**: **The picture**, then spots placed by **% across** and **% down**, each with a title and what it shows. - **Before and after**: two pictures, each with **Its label**, and **Where the divide starts**. Every picture needs a description, or **Decorative** switched on, before the activity can publish. ## Interactive video Give **The video** a **Video address**: a YouTube or Vimeo link, a video file, or one from the library. Then add stops. For each, set the **Minutes** and **Seconds**, and choose **At this stop**: **A note** or **A question**. A question can be any of several quiz kinds. Switch on **Students must answer to go on** to make the video wait there. ## Branching scenario A scenario is scenes joined by choices. For each scene, say whether **This is** **A scene, with choices** or **An end**, and mark the first with **Students start here**. Under **Choices**, **Add a choice**, then set **What students choose**, where **It goes to**, and optional **Feedback**. For an end, choose **How it ends** (**Well**, **Neither** or **Badly**) and **Its score, 0 to 100**: a student's mark is the score of the end they reach, out of the best end's. **Students can go back** lets them undo their last choice. ## Self-check Students think about a prompt, or type an answer if you switch on **Students type an answer first**, then reveal your **Model answer** and compare. It is never marked. **Add another prompt** adds more.
