Communicating with the public
You should spend some time considering who your audience is, what they may know, and why they’re engaging with your communication.
For non-expert audiences, the level of scientific knowledge can vary considerably. Although we often group all non-experts into a single group (the public), in reality there are many publics, all with a variety of knowledge, experiences, and opinions. Therefore, rather than simply “dumbing down” a topic, you will need to spend time on planning your communication activity to ensure you engage with your audience and achieve your purpose.
The planning process for communicating with a non-expert audience should be no different to the planning process used for communicating with your peers or an expert audience. However, you may find that context plays a larger role (particularly for controversial topics) and you may have more flexibility when choosing a genre.
Storytelling for science
Storytelling can captivate audiences.
Unlike a formal scientific article or presentation, storytelling allows you to connect with your audience through a variety of storytelling techniques, using emotion, metaphors, anecdotes, and images to incite wonder and interest in science.
The following Radiolab podcast is a great example of telling a science story (begin at 2:25).
Consider how you can use storytelling to communicate your scientific message.
Jargon and technical terms
If you do need to use technical terms, you should ensure you provide clear explanations or use well-designed diagrams or photos to help your audience to understand the key concepts.
Assessing the context
It is essential to consider the context around any communication with a non-expert audience. Failing to consider context could result in your communication activity failing to achieve its purpose. This is particularly important for controversial topics or topics that generate strong emotional responses (e.g. vaccination).
Choosing the right genre
Different genres can attract different audiences, so you need to think carefully about which type of communication activity will engage your target audience and how it should be structured to achieve your purpose.
Popular genres for general audiences:
- Public talks
- News articles
- Magazine articles
- Social media
Regardless of the genre you choose, you should attempt to customise the genre for different situations or different audiences.
For example, a public talk on scientific research doesn’t have to be a scientist talking for 50 minutes and answering questions for 10 minutes. Instead, more time could be spent interacting with the audience and answering questions, other experts could participate in a panel discussion, or the audience could interact with scientific models or displays.
Define your topic and audience
The blog genre allows you to write about almost anything for a range of audiences; however, you should define your topic, audience, and style early on.
Your blog posts should have a common theme and your content should be set at an appropriate level for your audience. Blog posts can focus on very specific topics (e.g. a blog about infectious diseases) or cover a wide range of topics (e.g. a blog about health).
Some blogs will have a news format whereas others may provide in-depth analyses or simply talk about the author’s life as a scientist. The options are endless.
Breaking up the content
Blogs often have a variety of content including opinions, reviews, video, audio, images, and links. You should aim to provide some variety for your audience.
Blogs posts that include a large amount of text will usually break up the content into distinct sections with headings and use short paragraphs.
Sometimes, the paragraphs are only one sentence long.
This allows an audience to scan through the text, choosing to read sections that interest them.
Bullet points, lists, quotes, and occasional bold highlights will also break up a lengthy blog post and improve readability.
Assessment items that require a vlog will vary in their requirements. Be sure to check your assessment criteria for specific details or talk to your lecturer.
For assessment items that require a recorded PowerPoint presentation (or similar), refer to the presentation module.
Writing a vlog script
At university, video assignments may require you to provide an explanation of results, summarise a scientific article, or discuss a particular substance, process, or species. Regardless of the topic, in most cases your video should have an introduction, body, and conclusion.
Before reading further, watch the first 2 minutes of the following SciShow video by Hank Green. The video focuses on a scientific article about incubation calling by birds. Pay attention to how Hank summarises the article and provides simple explanations for specific concepts.
Your introduction should grab your audience’s attention, provide some background information, and lead them into the main content in the body section. Vlogs usually allow for a bit more creativity than a PowerPoint presentation or a written task, so don’t be afraid to try something different in your introduction to engage your audience.
In the SciShow example, Hank provides an analogy of a human mother playing music to her unborn child. This analogy helps to prime the audience for the following scenario involving bird incubation calls. Hank then introduces the topic of incubation calling.
You can begin a script by writing down the key points that you need to include in the body of your video. Check your assignment criteria for details of any specific information that should be included. For example, if you were providing a summary of a scientific article, you may need to discuss each section of the article or simply mention the key findings.
Consider what visuals you will use in your video and make a note of when they should appear in the video. Often the visuals you choose will help you to develop different sections of your script.
Once you have an outline of the information you want to include in the body section, you can transform the information into sentences. See below for script tips.
In the SciShow example, Hank provides details of the experimental methods and results. The explanations are accompanied by text, images, and a simple animation. Hank continues to provide further explanation for the behaviours and discusses possible benefits of the incubation calling.
The conclusion gives you the opportunity to discuss the ‘so what?’ question (i.e. why should your audience care?). For science vlogs, the conclusion can also give consideration to future research possibilities or limitations of research findings.
Hank summarises the benefits of a small body mass for Zebra finches and indicates that the mechanism linking incubation calling and body mass remains a mystery—this is the same as suggesting further research is required.
Refining a script
Once you have a rough draft, record yourself reading through the script. As a rough guide, 150 words takes about 1 min to read aloud. It is essential that you speak clearly and use pauses for emphasis—don’t rush your vlog to fit within the time limit!
If you are over time, remove any sentences that are not essential and refine lengthy sentences.
If you are under time, consider where you can add more detail to individual sentences.
Pay attention to any parts of your script that, when read aloud, don’t sound quite right. You may want to rearrange a sentence or modify particularly words to improve cohesion.
Storyboarding is useful if you have a variety of footage or images to display. The process allows you to visualise the different sections of your video and rearrange parts if necessary.
Once you have a script, use it to map out what will appear on the screen. You don’t need to be able to draw. Simply use rough sketches to illustrate the major sections or shots of your video. If you’re on the screen, you can draw a stick figure. If you’re displaying a graph, sketch a simple graph.

Tips for scripts
Write for the ear, not the eye
One of the problems with using a script is that when you read it out it just doesn’t sound natural. Try to make your sentences sound less formal by using short sentences and writing like you’re having a conversation with someone you know.
Using contractions (don’t, won’t, haven’t, isn’t etc.) in your script will make you appear more relaxed and conversational. If you haven’t used contractions, you should notice that when you read your script for the first time it will sound too formal for a general audience.
When reading a script or recalling a script from memory, you may forget to add emphasis to important words or syllables. This robotic, monotone style can be avoided by underlining or highlighting words and syllables that require more emphasis. When you read through the script, the underlined or highlighted words will help you to remember to use emphasis.
Use the script as a guide
Probably the best way to avoid sounding unnatural when using a script is to just use it as a guide. This method is particularly useful if you need to be on camera for most/all of your video. Read through your script a few times to get familiar with your content and then put the script aside. Don’t worry if you miss certain words or explain things in a slightly different way, as long as you cover all the essential parts.
Don’t try to do it in one take
Don’t worry if you can only remember small segments of your script—you can join all of your segments together during the editing process. Be careful that you use the same lighting and audio setup for each shot. You will notice in Hank Green’s video that he only says one or two sentences before a break. Some of these breaks are softened by cutting to other graphics or by using zoomed in shots.
When filming a video you will need to consider the technical aspects (e.g. sound & lighting) and your presentation skills.
The expectations for the technical aspects of your video may vary depending on the assignment criteria. However, for vlogs you should always make sure the audio is clear and the lighting allows your audience to see you.
The following tutorials include a range of useful tips for recording a video. The first two videos include details about filming with a tripod and microphone—don’t worry if you don’t have access to this equipment—just be mindful of sound quality and camera shake.
Filming a vlog is a difficult task that generally requires regular practice to perfect. The following video provides some tips to help you improve your skills when talking to a camera.

Video file sizes
Large video files can cause problems when trying to submit university assignments online. For best results, try to keep your video file size 25 – 75 megabytes/minute. It is recommended that you use a university computer for maximum upload speeds.
Reducing file size
The best way to reduce file size is to record your video using a low quality setting. If possible, choose to record your video using the VGA setting rather than HD. If you’ve recorded your video and the file is too large, you will need to compress the video file.
VLC Media player
VLC is a free video player for Windows and Mac OS that can be used to convert and compress your video files. More information
Software export settings
Video editing software will generally have an export function that allows you to save your video at a reduced quality and smaller file size. Search Google for information on specific software.
Editing a vlog should be a fairly simple process. Once you’ve recorded your footage, it’s simply a matter of trimming and joining clips, and adding any necessary images, text, or sound. Video editing apps for mobile devices will generally include all the necessary features for editing a vlog. So, it’s possible to streamline the whole vlog process by completing the filming AND editing on your mobile device.
