My name is Serena Nicoll. I am doing a science project investigating how students from different types of schools understand conservation of mass and volume. I am asking for your help in two ways. First, can you and your children ages 9 and older please take a survey? To fill out the survey, please visit h t t p s : / / w w w .survey monkey.c o m /s/L77RJKX/ . Second, can you please share this post so that everyone will see it? I am trying to get as many people from around the world to take this survey as possible. If everyone takes the survey and tells their friends, I will have a really great study! Thank you so much for your support!
