Answer (1)
### Scenario Breakdown:- **Problem:** Grade 7 students suffer from skin irritations during the rainy season, especially between June and August. The irritations occur when their skin is exposed to rainwater.---### Hypothesis:The skin irritations experienced by grade 7 students during the rainy season are caused by contaminants or irritants present in the rainwater.---### Variables:- **Independent Variables:** - Exposure to rainwater (rainy season vs. non-rainy season). - Presence of contaminants in rainwater (pollutants, pH levels, etc.).- **Dependent Variables:** - Severity and frequency of skin irritation. - Types of skin reactions (rashes, redness, itching).- **Controlled Variables:** - Age group (all are grade 7 students). - Duration of exposure to rainwater. - Type of soap or skin products used by the students. - Location (same locality for all students). ---### Methods or Procedure:1. **Sample Selection:** - Select a group of grade 7 students in the locality. - Ensure equal representation of students who are frequently exposed to rainwater and those who are less exposed.2. **Observation Period:** - Monitor the students for skin irritations over the rainy season (June-August). - Record when and how often the students are exposed to rainwater.3. **Rainwater Testing:** - Collect rainwater samples at regular intervals during the rainy season. - Test for pollutants, pH levels, and other contaminants that could cause skin irritation.4. **Skin Condition Documentation:** - Keep a log of the students' skin conditions before and after exposure to rainwater. - Record symptoms like itching, redness, swelling, or rashes.5. **Data Analysis:** - Compare the frequency and severity of skin irritations between students who were exposed to rainwater and those who were not. - Analyze the correlation between rainwater contaminants and the skin irritations experienced.---### Result:- If a significant number of students experience skin irritations correlated with rainwater exposure and the presence of contaminants, this would support the hypothesis that rainwater contaminants cause the skin irritation.- If no significant correlation is found, further investigations into other potential causes (e.g., allergies or pre-existing skin conditions) would be needed.
