Sugary Deicing

Finding economic, environmentally friendly, and effective deicer in sugary family
Maryam Kazmi
Grade 6

Hypothesis

If I use an deicer with more sugar then it will be more effective as a deicer because the sugar in things like beet juice helps ice melt faster.

 

                                                                                                       

 

Research

  • Sugar helps melts ice because, like salt it lowers the freezing and melting point of ice. Sugar will dissolve on ice and interfere with water molcules, not allowing it to freeze.

  • Salt is more effective than sugar, both are not environmentally friendly

  • Water helps melt ice faster because the molecules are quite tightly packed together which will allow more contact with ice as well as larger amout of heat transfer.

  • Even though sugar is not environmentally friendly, beet juice does melt ice because of the present sugar

  • Salt although more effective than beet juice has many disadvantages to the environment

 

Per 1 cup

Orange = 17 g sugar

Apple = 11 g sugar

Banana = 18 g sugar

Beet = 9 g sugar

Honeydew melon = 14 g sugar

Molasses = 252 g sugar

Honey = 278 g sugar

Grapes = 15 g sugar

Variables

Manipulated Variable : Types of deicers                                     

Responding Variable : Amount of melted water 

Controlled Variables : 

  • Size & shape of container

  • Amount deicer used

  • Time to freeze each ice block

  • Duration of observation for each block

  • Surrounding environment for each block - temperature, pressure, time of day

 

Procedure

  1. Gather all Materials    

  2. Use measuring cup, 200ml water in each container                                                                  

  3. Put all containers in freezer, allow to freeze for 24 hours                                                         

  4. Take out all containers, place in same area                                           

  5.  Measure out 15ml of each melter, ( 1 melter per block )        

  6. Take observations every 30 min till 3 hours

Analysis

Conclusion

  • Hypothesis was correct

  • All sugary deicers more effective than control

  • Banana paste least effective

  • Sugar water most effective and most economic

  • Beet juice and apple juice most environmentally friendly

  • If choosing a deicer, depends on what you value most

Application

  • More options for deicers 

  • Melt ice on sidewalks & roads

  • Prevent slips, slides and falls

  • Safer environment

Sources Of Error

  • Experiment to short, ice didn't fully melt

  • Molasses & honey sticky, wasn't able to measure out precisely

  • Did experiment twice, but different times of day, different tempertures

  • Indoor conditions weren't same to outdoor conditions
