=====FUN PALACE 2018 non newtonian fluid===== Solid? Liquid? Or something else entirely? Play with custard's weird cousin and take home the recipe. ===Activity Details=== **Type** **Duration** **# Deliveries** **Duration** ===Activity Criteria=== ===Learning Outcomes & Facilitator notes=== - **Fun fact** - A non-newtonian fluid is a thixotropic fluid which changes its viscosity when the forces on it change - **Interesting fact for a child/teenager** –If you filled an entire swimming pool with custard (which is a Non Newtonian Fluid) , you would be able to walk across it! - **Interesting fact for an Adult** - Ketchup becomes thinner and runnier under impact, that’s why it helps to bang the end of a ketchup bottle when you’re struggling the get some out! - Image - https://goo.gl/images/kkCio4 or https://goo.gl/images/X2nko6 Lets You Walk On Water - **QLD collection:** http://onesearch.slq.qld.gov.au/primo-explore/fulldisplay?docid=slq_alma21223288740002061&context=L&vid=SLQ&search_scope=SLQ_PCI_EBSCO&tab=all&lang=en_US The Big Book of Glues, Brews, and Goos : 500+ Kid-Tested Recipes and Formulas for Hands-On Learning. Diana F. Marks E-Books are great for learning through play at home ===Session Plan=== ==Part 1-What is Non Newtonian Fluid? And how does it work?== What is Non Newtonian Fluid? Interesting question... before we answer that we need to who was Newton and **what he thought about fluids** See this link that provides a great summary? [[https://blog.viscosity.com/blog/picking-up-where-sir-isaac-newton-left-off-newtonian-vs.-non-newtonian-fluids]] The moral of the story is that even Newton got stuff wrong and thats why science is still important. **But How Does It work** Well we still don't really know but lets run an experiment. and see if we can come up with a theory. Experiment Control - drop something into a container of Newtonian Fluid (water) From a from the surface and from a standard height of metre [[https://en.wikipedia.org/wiki/Viscosity#/media/File:Viscosities.gif]] who first described Non newtonian Fluid ===Materials Req=== Begin with 500mL water per kilogram of cornstarch, and gradually add more water until the mixture has the consistency of honey. ===Equipment Req=== ===Files=== https://blog.viscosity.com/blog/picking-up-where-sir-isaac-newton-left-off-newtonian-vs.-non-newtonian-fluids https://www.sciencelearn.org.nz/resources/1502-non-newtonian-fluids https://phys.org/news/2011-09-physicists-capture-microscopic-thinning-thickening.html ===Reflections Learnings=== ====Gallery====
