Solution

Consider the following test results: Clear no particles settle out no Tyndall effect nothing in filter paper

Solution

Chocolate milk (milk, water, syrup, etc.)

Suspension

Consider the following test results: Cloudy Particles settle out The Tyndall effect is blocked out (so there is NO Tyndall effect) Solid material shows up in filter paper
