To engage the audience and make sure you have their full attention you need to make sure you connect with them. You can connect with the audience by the use of eye contact, this shows that you are involving them directly. If you use effective body language it shows that you want to engage with the audience.

Modulating your voice is when you use a certain tone depending on your audience. Your vocabulary is also important. If you are interacting with younger people you don’t want to be using words they may not understand. However, you don’t want to come across as patronising if you are delivering a presentation to adults. 

When summarising after reading the source until you fully understand, you need to show a clear indication of the main points in your own words without using the same word or phrase as the original. 

You must use open body language when presenting to your audience. An example of bad body language would be closed body language this includes things such as crossing your arms. If you have your arms crossed when delivering your presentation it gives off the impression you don’t want to communicate effectively with your audience. You need to use facial expressions as this can show enthusiasm, if you come across as boring people wont want to listen to you and it is important you have your audiences full attention. 

You must be polite and speak to people in a formal manner. For example swearing, this could offend people and make them question how professional you are.
