UV Radiation Protection in Sunglasses
Nov. 11, 2019
Spoke with my mom about science fair
and decided I should work with Amy.
Nov. 14, 2019
Looked online for some project
ideas. I would like to do a project
about sunlight and UV radiation. I
couldn’t find anything today, so I will
continue to look
tommorr
tomorrow.
Nov. 17, 2019
Found a couple of ideas I liked.
1. I will use UV glo-in-dark beads
to test which sunglasses protect from
UV radiation the most.
2. I could test which solar powered
yard lights stay powered the longest.
I will go ahead and turn these into
the teacher on the blue form and get
Approval.
Nov. 19, 2019
The teacher liked my first idea.
So, my question is Which colored lens
of sunglasses

What Is Ultraviolet Light?

Planet Earth
Ultraviolet light is a type of
electromagnetic radiation that makes
black-light posters glow, and is
responsible for summer tans — and
protect against UV radiation the
best?
sunburns. However, too much
exposure to UV radiation is damaging
to living tissue.
Electromagnetic radiation comes
from the sun and transmitted in
waves or particles at different
wavelengths and frequencies.
Source of Info:
https://www.skincancer.org/risk-
factors/uv-radiation/
Two types of UV light are proven to
contribute to the risk for skin cancer:
Ultraviolet A
(UVA) has a longer
wavelength, and is associated with
skin
aging.
Ultraviolet B
(UVB) has a shorter
wavelength and is associated with
skin
burning
.
While UVA and UVB rays differ in how
they affect the skin, they both do
harm. Unprotected exposure to UVA
and UVB damages the DNA in skin
cells, producing genetic defects, or
mutations, that can lead to
skin
cancer
(as well as premature aging.)
These rays can also cause
eye
damage, including cataracts and
eyelid cancers
.

Hyptheisis
Hypothesis: If I block
the sun using the yellow Sun-Eze
Glasses, the brown Sun-Eze lenses,
And the mirrored Sun-Eze lenses, then
the UV beads will react faster with
The brown lenses because dark colors
absorb more light and therefore
will make the beads change faster.
Nov. 24, 2019
Today I am beginning to gather my
materials. Looked on Amazon
To get the UV beads and the
different kinds of sunglasses.
I will also need a timer.

In this science fair project, the aim is to investigate which colored lenses of sunglasses offer the best protection against UV radiation. The project involves using UV glo-in-dark beads and various types of sunglasses to test their efficacy in blocking harmful UV rays. The background research includes information on the types of UV light, their effects on the skin, and the risk for skin cancer. Gathering materials and formulating a hypothesis are crucial steps in this experiment. Stay tuned for updates on the progress!
