Science Experiment


Experiment

Put one spoonful of sugar into one of the bottles use the plastic funnel to guide the crystals into the bottle. Add the sugar slowly so that it does not block the neck of the funnel.

Repeat step 1, placing each of the other solids (fine sand, instant coffee granules, plain flour) in its own bottle. Now half fill each bottle with water and screw on the cap. Shake each bottle ten times.

Look carefully at each bottle to see if you can still see solid particles. Decide which solids form a solution and which solids form a suspension.

Solutions and Suspensions


LI: I am learning to write an introduction to my Science Project.

Solutions and Suspensions


It is very important to know and understand the introduction to a particular topic to carry out the experiments successfully. My project is about “Solutions and Suspensions”

Introduction
Solutions

A liquid in which a solid substance has been dissolved.

Example: Sugar and Water

Suspensions

The particles in suspensions are larger than those found in solutions. Components of a suspension can be evenly distributed by a mechanical means, like by shaking the contents, but the components will settle out.

Example: Oil and Water
