Saturated Salt Solution
How many grams of salt did it take to saturate 50ml of water? What does saturated mean? What did we use as a solute? Do you think the water could hold more salt if the water was heated or cooled?
Natural Selection Graphs and Analysis
For the Natural Selection Lab, make graphs for all of your data. If you did not finish the lab, make prediction graphs for the parts you did not finish and explain why you predict these results. For your analysis, explain the results of each simulation, to include the questions asked on yesterday's blog post. Include how this activity was a representation of actual events. Also include the limitations of this activity (for example, how could you have manipulated the results)

Natural Selection Lab
How did the color of the environment (paper) effect the population (macaroni)? What happened after several generations? What do you predict will happen when you use white paper? What do you think would happen to these species if there were no predators? What would need to occur for speciation to occur? How does this activity relate to evolution, natural selection and the fitness of a species?
