Right out of a Ghost Busters movie this slime is the real thing made from polyvinyl alcohol. This slime is similar to the Guar Gum slime you may have made before and with significant differences that are worth a second look at. This slime is made from a synthetic polymer called polyvinyl alcohol and not the polysaccharide used in guar gum slime. Thus it lasts much longer, is crystal clear, and its viscosity is easier to adjust. PVAlc is an emulsifier and it is possible to dissolve polar and nonpolar material in it.
Making Slime is one of the most popular lab activities you are apt to find online so you may wonder what sets this one apart from all the others. Making slime is certainly a very fun thing that everyone should experience, and I am a big advocate of having some fun with science, but the is much more to the study of science than that. With this in mind I have tried to add conceptual drawings that will aid your students to connect what they see and feel macroscopically with the microscopic and molecular world. Also this lab includes a real life quantitative analysis of the slime which mimics the kind of experiment that an engineer or materials scientist might conduct by measuring the ‘creep’ of the slime.

A word about ‘Zip Labs’: Horizontal & Vertical Lesson Planning
In general, Zip Labs are science and math activities broken down into ‘horizontal and vertical’ educational increments. By ‘horizontal’ increments I mean each activity can be completed in a minimum of 60 minutes. However, the teacher, and/or student may choose to extend the activity over a longer time period or even days. By ‘vertical’ increments I mean each activity is broken down into segments according to grade and difficulty level. So teachers and/or students can decide where to start and how far to go with the topic.
Each Zip Lab includes potentially much more than any teacher will use at the particular grade level he or she may teach. However, it is my hope that teachers, and students, at lower grade levels will gain valuable insight by looking ahead to see how their teaching/learning will be applied in the future. While teachers and students at higher grade levels can reflect on topics that they should have learned in earlier grades. It is my hope that students see their education as a continuum rather than a series of disconnected and random topics.
Zip Labs include diagrams and illustrations that I hope are appealing to a wide range of ages. However, teachers can choose to omit them if they like. Also included is a Common Core ‘Depth of Knowledge’ (DOK) and grade level range ‘sliding’ indicator to help students visualize the relevance of their work.
New in this activity, optional QPA, (Quality Performance Assessment) ‘Stamps’ for Competency Based grading as well as differentiated lesson planning!
This unit activity meets or exceeds 21st Century and STEM learning expectations, and Common Core learning outcomes. Note: although ZIP-labs fulfill many CCSS, specific CCS standards are not listed because ZIP-labs are designed to be used over many graded levels so the specific CCSS may be different depending upon these factors. For a list of CCSS in your state please visit- www.corestandards.org
New – Integrated Holistic QPA, (that’s Quality Performance Assessment) created by me! This activity requires NO RUBRICS! The rubric is integrated into the activity itself. Much less work for you and far more meaningful to your students.
