Dissolving Scientific Report

 Hey Bloggers, 

In writing this week we done another experiment on with substance will dissolve faster in water. We had to write another report and present it in any way we wanted too. This is my report: 

Wondering: I think that the sugar will dissolve quicker      

Hypothesis: i think that the sugar will dissolve quicker because in warm or hot water it melts because all the sugar grains dissolve into the heat

Materials: 

½ a tablespoon of the following substances:

Sand

Corn Flour

Salt

Sugar

Flour

Citric Acid

A tablespoon

Timer

Beakers

Warm Water

Variables:

Independent:  powdered substances

Control: amount of water

Dependent: the substances dissolving

Procedure:

1. Fill 6 beakers with 80ml of warm water

2. Get ½ a tablespoon and put them into the beakers

3. Time and stir throughout the procedure

4. Observe      

 

Results/Observations:

The citric acid dissolved first, then the sugar and last but not least the salt. The sand, flour and cornflour didn’t dissolve at all. The cornflour and flour turned into a gluey kind of substance instead of dissolving.

Conclusion:

 In conclusion the hypothesis was wrong because the citric acid was the one that dissolved the quickest. The sugar was second because when you put the sugar in the water you can see the sugar but when you mix the sugar and the water molecule together. When sugar is mixed with a warm or hot substance it dissolves into the solvent, for example when you make a cup of tea and you add sugar it dissolves into the tea. The sand, corn flour and ordinary flour didn’t dissolve, the flours turned into a gluey substance and the sand just stayed there.

Thanks for reading :)
