Does Sunscreen
Have as Much Effect as You Think?
Find Out Here!
I experimented with
three different levels of sunscreen to find out the answer.
Summary
The hypothesis of How much more protection does a higher SPF rating give from UV rays?
is a higher SPF will give a lot more protection fro the UV rays. The
application of this experiment is to see if the experiment will show if there
is a big difference between SPFs. It will see if you need to spend more money
for sunscreen. If you get a 50 SPF and only get to stay out five minutes longer
than a 30 SPF, and it was ten dollars more. Is it really worth it?
When I scanned it for the base rating it came up as
high, which is off the charts and it said to be outside for 0 minutes. Then I did my control, the 2 layers of Saran
wrap on an embroidery hoop. It resulted the same. Then I took the 15 SPF, 30
SPF, and 50 SPF, and it came out as a zero UV and you could stay outside for an
estimated 40 hours. I even tested it a few more times and it resulted the same.
I even tried a stronger tanning booth, but it still made no difference. My
results were inconclusive. I applied each of the sunscreens the same to get the
same measure. So what went wrong? My project may have not worked because of the
tanning booth only had one UV and the sunscreen blocked it. Maybe it was
because it wasn’t real sunlight or because the sunscreen really did block all
of the UV rays.
Hypothesis
A higher SPF will give a lot more protection from
the UV rays.
The purpose of this experiment is to test to see if
a how much more a higher SPF on sunscreen blocks more UV rays than a lower SPF.
I will also test the exposure time to how long you can be out in the sun with
the different SPF ratings of sunscreen. This will show if it is worth it to pay
a more money for a higher SPF. The scientific value of this experiment is it
will affect what sunscreen people will use and how long they’ll be out in the
sun wearing it.
The conclusion of my project How much more protection does a higher SPF rating give from UV rays? was
unexpected. My results were inconclusive. I expected that the higher SPF would
give more protection from the UV rays, but it doesn’t. All of my sunscreens
provided equal protection from the sun, which was it blocked all the UV rays. I
found that no sunscreen and the base rating came up as a HIGH UV, which is off
the charts, and you shouldn’t be out in the sun at all, though. I applied each
of the sunscreens the same to get the same measurement. So what went wrong? I
know it wasn’t the Saran wrap, because when I did no sunscreen, I did that with
plain Saran wrap, and it came up high. My project may have not worked because
of the tanning booth only had one UV and the sunscreen blocked it. In
conclusion, my hypothesis was proved to be wrong.
