- A new sunscreen claims to be better at preventing sunburn then any existing brand on the market. To test this claim, students rub the new sunscreen on one arm and another brand on their other arm and stand in the sun for 4 hours. Write a hypothesis for this test. What is the independent variable? What is the dependent variable? List two (or more) ways to improve this experimental design.What are three important thing you will consider when settting up an experiment to investigate a phenomenon? Explain why?What variable is the one that you can manipulate or change? It is sometimes called experimental variable
