Second Blog Submission - the Plan of Experiment

Aim: To investigate the relationship between the transparency of glass to UV radiation and the thickness of glass.

Hypothesis: The thicker the glass, the less transparent it is to UV radiation.

Equipment:

- Clear 3mm thick soda-lime glass (x5)

- UV monitor (x1)

Risk assessment (table):
See Picture 1 above.

Method:

1. Hold one piece of the glass perpendicular to the sunlight

2. Put the UV monitor under the shade formed by the glass

3. Measure the UV radiation level and record

4. Repeat procedure 1-3 four times. Add a piece of glass on top of the original glass UV filter each time.

5. Repeat procedure 1-4 4 times in a similar weather condition. Test 5 weather conditions in total, thus a total of 25 repetitions of experiment.

Results (table design):
See Picture 2 above.
