The oobleck, or cornstarch-water, mixture can act like both a solid and a liquid. This mixture is a suspension. A suspension is a mixture of two substances- in this mixture, it’s a solid, corn starch, dispersed in a liquid, water. Sir Isaac Newton stated all liquids have viscosity: a measurable property that determines the thickness of a liquid or resistance of that liquid to flow. Newton also stated that viscosity changes with temperature. A change in temperature results in a change in viscosity

indicates the presence of glucose. The IKI moved from the beaker into the dialysis bag, this resulted in a change of color to black within the bag. This made the concentration within the bag equal to the concentration outside the bag. The glucose solution moved out of the bag making glucose present in the beaker. The glucose moved to make the solute concentration inside and out equal. If the initial and final % concentration of glucose and IKI for in the bag and in the beaker were given they
