Incorporating HVG clips into your presentations, and drinking cockroaches!

We’ve had a query about linking to HVG clips so that they can be displayed within PowerPoint presentations. The best way to do this is to copy and paste the hyperlink to the relevant clip into your slide, and then click on it once you get to the right point in the presentation. You just need to make sure that you are logged-in to HVG in the background. If you aren’t logged-in already you will be taken to the HVG login page and then go through directly to the clip once you have entered your login details.

As promised previously, here is a sample clip from the new KS3/Go Science! module. Despite the considerable ‘yuck factor’, this has to be one of my favourite clips from the module.

The clip shows part of a simple investigation into human behaviour. Children of differing ages are offered a drink of juice containing a dead cockroach. Young children will drink the juice if the cockroach is removed, but adults will not. The video would make an interesting introduction to the topic of investigating behaviour as it shows a psychologist and one of his experiments.

If you do use this clip in the classroom, you might want to warn your pupils that it is quite shocking, and that they may wish to look away at times while it is showing. To link back to the ‘Investigating human behaviour’ theme, it would then be interesting to find out if any of them were motivated to watch the clip more closely as a result of the warning?

The part of the clip that I find most disturbing is that the psychologist lets the children continue to drink the juice after they have clearly demonstrated their willingness to do so. Surely he could have stopped them – the youngest child nearly finishes the whole cup! Or perhaps that is just my particular cognitive level of perceiving the situation manifesting itself…

Title of clip	That’s disgusting – or is it?

Description	A series of clips show people of different ages being asked to drink a glass of apple juice with a cockroach in it. The experiment demonstrates how learnt behaviour and emotional response changes as we grow older. An expert in the field explains how a person’s cognitive level of perceiving a given situation improves with age until a threshold is past – in this example around the age of seven.
