A fresh inquiry update to our popular Sunscreen for Yeast - and People Too! Kit
- Directly demonstrate the importance of DNA repair systems
- Meaningful real-world connection for students
- Learn how to best prevent/minimize exposure to ultraviolet (UV) light
Using a UV-sensitive mutant strain of the yeast Saccharomyces cerevisiae, students investigate the impact of UV light on living organisms. The S. cerevisiae mutant strain is extremely sensitive to UV light because it lacks an effective method for repairing damaged DNA. In the first activity, students determine the impact of UV light on 2 strains of yeast, wild-type and UV-sensitive. After understanding the true impact of UV light, students then have the opportunity to design their own inquiry investigation to determine how to best prevent UV damage to the UV-sensitive yeast strain. In the second activity, these investigations can have students testing various sunscreens, cloth samples, or myriad other options of their own choosing. This entire activity is accomplished in 3 to 4 class periods and will truly give you a great starting point for discussing DNA repair systems and the impact of UV light on the human body. This 8-Station Kit provides enough materials for 32 students working in groups of 4, including a prepaid coupon to request perishables later at your convenience.
