Today in class we did a dilution lab! We started with a stock solution containing 20 drops of red food coloring and took equal portions of that stock, added 9 mL of water to each aliquot, and put that new substance in a new cup. We kept doing this until the liquid was clear.
Overall, this lab was really helpful in learning how to solve real life dilution problems!
Here are some links if you need more help with dilution:

Marie, I like the pictures you added of the lab! They were helpful in showing what happened. I also like how you added the links about dilutions. I found them to be very helpful in explaining things a little further.
