How to Use this Blog

The key feature about a blog is that new articles are at the top and older ones are at the bottom. There will be links to useful sites you might want to refer to at the right-hand side of the blog. If you come across any websites which you think everyone would benefit from let me know and I will add it to this blog.

Welcome

Welcome to the website for the HN Unit Electro-Cosmetic Therapy.

It is for students in Clydebank College studying HND Beauty Therapy. The website will act as a log of what is done each week and will give links to other websites which will help you prepare for your final assessment.

Sunbed Association

Clicking on the title above or here will take you to the Sunbed Association website. By the end of this course you will be able to judge for yourself whether the information given is accurate or not. This link was provided by a student a couple of years ago. I have included the link to give another point of view.

Illuminance (Light Intensity)

The light intensity depends on two things
. The distance from the source - Inverse Square Law
. The angle of the surface to the beam of light.

These are described in more detail here.

Smarter Scotland

When Smarter Scotland were looking for students who used science in ways that school pupils may not think about Clydebank College was approached. Chloe Galletly volunteered to do an interview and it was published in the DoScience website. Here is a link to the interview.

Inverse Square Law Experiment

There are two laws you should know about radiation. Can you state them?

Clicking on the title bar will take you to a brilliant simulation. It uses Flash Player which has now been updated in the college computers.

What is the meter reading when the distance between the bulb and the detector is 100 cm.

Now now half the distance. What do you think the reading on the meter will be now? What is it actually?

Try this again. Choose a distance of 90 cm. Meter reading =

Now reduce the distance to one third of 90 cm. What reading do you expect?

What is the new meter reading?

Now choose an original distance of 20 cm. Take a note of the reading. Predict what the reading will be when the distance is 80 cm. Now do it. Was your prediction correct (roughly)

Describe what is happening in your own words.

Can you please let me know if you were able to use the simulation. Just leave a comment and say whether you were using it at home or on a college computer. If it does not work at home you might need to download Flash player. You can do this by clicking here.
To leave a comment you can select 'anonymous' and type in the fuzzy letters. Thanking you in anticipation.

90 degree rule


The intensity of the radiation is greatest when the radiation hits the surface at 90 degrees.

What causes a Tan?

This link is to a nice easy animation which shows the damage caused by UV.

This is heavy reading but has everything you need to know about sunbeds.
