             Hypothesis- The substances put into the Alcohol will dissolve faster than the substances placed into the regular chilled water.
             Purpose- The purpose is to find out if all solvents are alike or do some solvents dissolve substances faster than others.
             Materials .
             Safety goggles.
             Chilled water.
             Isopropyl (rubbing alcohol).
             Test tubes.
             Rubber stopper.
             Ray box.
             Rice.
             Salt.
             Margarine.
             Drink crystals.
             Cornstarch.
             Procedure.
             1- Pour alcohol into a test tube and add a pinch of salt.
             2- Put a rubber stopper onto the test tube and than shake it away from your body while counting to five.
             3- Repeat steps one and two with all of the substances in the alcohol. If you are not sure if it heterogeneous or a homogeneous mixture shine the ray box light on it to get a better look.
             4- Remove all substances from the test tubes and make sure that you get as much water out of them as you can.
             5- Repeat steps one and two with the chilled water.
             Qualitative observations.
             Alcohol + Rice = when mixed it was very murky it rattled when we shook it and it was a Heterogeneous mixture.
             Alcohol + Salt = when mixed together there was no colour change. A few of the crystals dissolved instantly but still under the ray box you could still see some crystals floating in the water. It was a Heterogeneous mixture. .
             Alcohol + Margarine = when mixed together they formed a milky colour it had a very thick texture by the looks and it was a homogenous mixture.
             Alcohol + Drink Crystals = When mixed together there was no colour change. And it was a heterogeneous mixture.
             Alcohol + Corn Starch = When mixed together the formed a murky milky colour and it was a homogeneous mixture.
             Water + Rice = when mixed together the water turned a murky colour. And it was a heterogeneous mixture.
             Water + Salt = when mixed together they formed a translucent white colour. And it was a homogeneous mixture .
             Water + Drink Crystals = When mixed together the formed a purple colour but all did not dissolve only some of the drink crystals did.
