Making Paper Science, level: Pre-School Posted Wed Jun 23 13:39:34 PDT 1999 by Anmarie McFadden (am1@students.uwf.edu). St. Paul's Preschool, Pensacola, Florida USA Materials Required: scrap paper, water, blender, large mixing bowl, screen Activity Time: 30-45 minutes Concepts Taught: conservation, changing physical states, recycling Procedures: 1)save classroom paper scraps for several days. Children may also want to bring in some from home. (I encourage this so that they can feel they have provided something personal to the project & they can inform parents about the need for recycling.) 2)set up blender (or can use a food processor). 3)explain blender safety: a. only an adult can use the blender because of sharp blades. b. The lid must always be on the blender until all motion of the blades has stopped. 4)have students begin to add a few small scraps of paper into the blender pitcher. 5)add just enought water to thoroughly soak paper. 6)place lid on the pitcher and begin blending. 7)after a few seconds, check the mixture. Add water and paper as needed. 8)empty the pulpy mixture into a bowl. 9)repeat steps 4 through 8 until bowl is nearly full or until each student has had a turn helping create the mixture. 10)outside, or over a large basin (a water table is ideal!)pour and spread the pulp in the bowl over the screen. 11)place the screen outside or in a warm, dry area for several hours. (overnight is best!) 12)after several hours, touch the screen to see if the pulp is dry. 13)when pulp is dry, slowly peel the paper off the screen. 14)cut the paper into small squares for each student. Discussion: 1)talk about what happened to the paper when water was added to it. What happened to it in the blender? 2)why did it go back to being like paper? 3)how is this paper different from the paper we use to write and draw on?       June: The 30 Days of Teachers.Net (Introduction) 1 The Gazette 2 The Mailrings 3 Harry Wong 4 Lesson Bank 5 Tech Center 6 Teacher Classifieds 7 State Teachers.Net 8 Live Chat & Meetings 9 Teacher Printables 10 Project Center 11 Chatboard Network 12 Share Teachers.Net 13 Your Feedback 14 Interest Groups 15 Administrators.Net 16 Chat Center 17 Streaming Teacher Video 18 Tutoring Center 19 Academic Grants 20 Teachers.Net Bookshelf 21 Chatboard Tips 22 Grade Levels 23 Staffroom Flyer 24 Teachers.Net Archives 25 Hot Topics 26 Language Arts 27 Subject Areas 28 Quick Links 29 Meet Teachers.Net 30 Summer Job Fair
