Summer Learning Journey | Day 7 | Activity 3: Ultraviolet

For the ultraviolet activity on day seven (activity three), I learnt about UV light and indicators. Using a google draw, I created and came up with my own ultraviolet ray indicator.

UV rays (ultraviolet light) are naturally sourced by the sun. However, when a person, animal or thing is exposed to UV rays for too long, it can cause damage like rusting and sunburns.

There are three kinds of UV rays: UV-C, UV-B and UV-A. 

UV indicators identify the strength of the ultraviolet rays. By knowing how strong a UV ray is, it allows a person to know how and when to protect themselves in certain situations with different UV ray levels.

First, I watched a video that explained what UV rays are, the effects of UV rays, what a UV indicator is and its purpose. This helped me get a better understanding of what I had to create and include in my UV indicator.

I created a UV ray indicator wand that uses light sensors to catch UV rays and transmit them to a UV reader, which identifies the type of UV light. It also provides the strength of the UV rays in percentage. The wand's base is made out of strong and flexible glass so the light can pernitrate properly.

This was a really fun activity and I very much enjoyed researching about ultraviolet light, indicators and creating my own indicator.

What I found most challenging or difficult about this activity was thinking about how the UV light indicator would work and manage to capture light.

This was a great opportunity to learn more about ultraviolet and use different comprehension skills to learn something new.
