Oobleck is supposed to be one part corn starch to one part water... however, this recipe never works well for us. We do about double the amount of corn starch - but I like a thicker goo. It is a lot more fun to work with when it is thicker. Of course, we added a tad of green food coloring to create 'Oobleck'. Such a fun sensory experience!
Later in the day we enjoyed One Fish, Two Fish, Red Fish, Blue Fish - this is a favorite of mine. After the story Holly did a book review, did a fish lacing project, she watched a video on Brain Pop on Tallying and graphing (her first introduction to tally marks) and then did two different projects with rainbow goldfish crackers - one with tally marks and one as a bar graph.
Holly then finished the day with a fish bowl art project in which she painted with colored corn syrup to create the water in a fish bowl, she designed a few fish to add with sea weed and rocks. After her project was complete you cover it with saran wrap which gives a very realistic water look - it is neat!
