Knowing non -Newtonian fluids is a special phenomenon that can be changed by stress or speed. Lead the elementary school vividly to experience its mystery.nAccording to legend, there is a kind of thing in the world. If you beat it hard, it will become hard to resist your strength; but if you touch it gently, it will become very silk to respond to your tenderness Essence What exactly is so special? Let's look forward to the mystery revealed!nNon -Newtonian fluids are under pressure or speed. If the expansion phenomenon will occur when the force is performed in an instant, the water molecules will be discharged instantly, and the corn flour molecules will be arranged neatly to resist external forces. However, if the pressure is slowly applied, the corn flour molecules have enough time to move, and the tight arrangement cannot be formed, and it is still a fluid characteristics.nActivity 1: Rescue eggs. Can Non -Newtonian fluid protect fragile eggs?nActivity 2: Do it to see-find out the non-Newtonian fluid formula. Observe the characteristics of the solution made from different proportions?nActivity 3: The speed is not reached-search master. The group competition found the most marbles in the Non -Newtonian fluid.n
