Title: Sunscreen Test - Exploring Sun Protection Experiment
Objective: To test and compare the effectiveness of different sunscreens in blocking harmful UV rays.
Materials:
- Several brands of sunscreen with varying SPF levels (make sure they are appropriate for children's use)
- Small squares of white construction paper or cardboard
- Marker or pen
- Tape
- Stopwatch or timer
- Access to sunlight
Procedure:
- Begin by discussing the importance of sun protection with the children. Explain that sunscreen helps to block harmful ultraviolet (UV) rays from the sun, which can cause sunburn and damage to the skin.
- Gather the materials required for the sunscreen test.
- Using a marker or pen, label each square of construction paper or cardboard with the name of the sunscreen being tested and its SPF level.
- Apply a generous amount of one sunscreen to one square, spreading it evenly over the surface. Ensure that the entire surface is covered with sunscreen.
- Repeat step 4 for each square, using a different sunscreen for each one.
- Choose an outdoor area with direct sunlight for the experiment. Place the squares of construction paper or cardboard in a location where they will receive the same amount of sunlight.
- Use tape to secure the squares to a flat surface, making sure they are positioned vertically and facing the sun.
- Set a timer or stopwatch to track the time.
- Allow the squares to be exposed to sunlight for the same duration of time (e.g., 15 minutes).
- After the designated time, carefully remove the squares from the sunlight.
- Observe and compare the squares of construction paper or cardboard. Note any changes in color or signs of sun damage.
- Discuss the findings with the children. Compare the effectiveness of the different sunscreens in protecting against sunburn. Emphasize that sunscreens with higher SPF levels tend to provide better protection against harmful UV rays.
- Reflect on the experiment and discuss the importance of using sunscreen and practicing sun safety habits, such as seeking shade, wearing protective clothing and reapplying sunscreen regularly.
Safety Considerations:
- Ensure that the children are adequately protected from the sun during the experiment. Consider conducting the experiment during a time when the sun's rays are less intense, such as early morning or late afternoon.
This experiment allows children to test and compare the effectiveness of different sunscreens in blocking harmful UV rays. It promotes awareness of sun protection, scientific observation and an understanding of the role of sunscreen in preventing sunburn and skin damage. Enjoy the process of exploring sun safety with this sunscreen test.
