6 Choose a claim from the Mini-project and write a short paragraph describing your experiment design in about 120 words. Your writing should include the following aspects: the research question, the participants in your experiment, the steps of the experiment and what results you think are possible.

答案： Research question: Does the smell of food affect people's perception of its taste? Participants: 20 students aged 18-22. Steps: 1. Prepare three identical cups of plain yogurt. 2. Blindfold participants and have them taste the first cup without any smell. 3. For the second cup, hold a lemon peel under their nose while tasting. 4. For the third cup, hold a vanilla extract under their nose. 5. Ask participants to rate the taste (sweet/sour) on a scale of 1-10. Possible results: Participants may rate the yogurt as more sour with lemon smell and sweeter with vanilla smell, showing smell influences taste perception.
