More Slime ActivitiesĬan you make a better slime? Try adding chia seeds to the Fybogel or using different amounts of water. Try asking children to predict which slime will be the best in each test based on their existing knowledge. Partial design process Grade Level: 8 (6 9) Time Required: 1 hours 45 minutes (two 50-minute class periods) Group Size: 2 Subject Areas: Summary Using their knowledge of the phases of matter, the scientific method, and polymers, student teams work as if they are chemical engineers to optimize the formula for slime. For each test discuss how to make it fair, for example standing the same distance from the splat board and throwing the same amount of slime. Slime flows like a liquid, but unlike familiar liquids (e.g., oil, water), its ability to flow, or viscosity, is not constant. This is a great activity for starting to think scientifically. 324 views, 20 likes, 2 loves, 0 comments, 2 shares, Facebook Watch Videos from FLIP Fluids Addon: An interesting viscosity (15) test with some slime. We’ve also got a creepy Halloween slime to try. We can’t wait to see how they do in our splat test!
These fluids change when put under different types of stress.įor example, when you put cream into a kitchen mixer and whip it fast, the cream gets thicker and turns into whipped cream - yum! The stress of the mixing changes cream’s viscosity, even when the temperature stays the same.For more fun slime recipes to test, try some of the great no borax slime recipes over on Red Ted Art. Observation of stretching the cross-linked PVA slowly: The slime flows and stretches. Non-Newtonian fluids also have changes in viscosity, but not just due to temperature. The mixture becomes more viscous (thicker). Both will flow faster when temperature rises, and both will flow slower when cooled. Slowly placing your hands on the slime is being described as a. At room temperature, water has a lower viscosity and flows faster than syrup, which is thicker and has higher viscosity. Slime, has a different viscosity, based on the amount of strength you apply when playing with it. Or, in more technical terms, the fluid’s viscosity changed. What he noticed is that fluids tend to get thicker or thinner when the temperature changes, affecting how fast or slow the fluids flow. Isaac Newton introduced the concept of Newtonian fluids. He’s also very famous for his three laws of motion. Newton spent a lifetime questioning and trying to explain the world - he would have been a great STEM Club scientist! Many know Newton from the story of an apple falling from the tree onto his head, which gave him the inspiration to investigate and explain gravity.
The Newton in Newtonian is none other than Sir Isaac Newton, the famed English scientist responsible for numerous scientific and mathematic advances in the 17th century.
