- What happens to the “food coloring” (the red molecules) over time in the glass of water?
- What is the independent variable for this experiment?
- What is the dependent variable for this experiment?
- Write a hypothesis about the relationship between temperature and the rate of diffusion.
- Which temperature do you predict will have the longest time for three blue molecules to reach the gas sensor (purple strip on the right side)?
- Which temperature do you predict will have the shortest time for three blue molecules to reach the gas sensor (purple strip on the right side)?
- Complete the table below by entering your experiment times and calculating the average for each temperature.
