1. UV light levels around the world



    This project has two goals:

    1.Discover how the Sun's UV levels vary during the day and across the globe

    2. Discover the level of awareness related to UV radiation in the communities.

    Research question

    1. How does the Sun's UV levels vary during the day in the same place?

    2. Are UV rays the same throughout the globe?

    3. What is the level of awareness of the community regarding UV radiation?

    Why use data from multiple participants?

    This project intends to give students a global view of the research questions.

    Investigation Protocol

    1. Expose the beads to direct sunlight in a non-cloudy day at the three following hours of the day

    9am, 1pm and 5pm

    and compare their colour to the colors of the UV radiation scale to see to which color it corresponds: Insert the results in the report form.

    2. At each of these 3 times, take a picture of the beads while exposed, save it and upload them in the report form.

    3. Use the interview items on the report form (questions 11 to 14) of this project to interview one familiy member about their opinions related to UV rays. Feel free to interview more people and register their answers in your notebook.

    Safety tips

    Make sure you protect your skin from the sun in case you are going to be exposed directly between 10am and 4pm.
