Science activity assignment

Dear Fourth Grade Families,

As your child may have told you, we will be doing a "surprise" science activity later this week, and I have asked each student to bring in some materials. First, EVERY child will need an empty clear plastic bottle with a cap--2 liter bottles or water bottles work best. Second, students are asked to bring one of the following items:

#1-6 vegetable oil (this does not need to be a full bottle, 2 cups should be plenty to share) #7-11 food coloring (this can be one color or several, and whatever is left will be
returned home)
#12-22 coarse salt/pretzel salt (just a cup or two in a ziploc bag should be plenty!)

Students will be keeping our finished "project" and bringing it home to show you! All materials are needed by this Wednesday, Dec. 2nd. Thank you!
