Our First Procedure:
Materials Needed:
All that is required is:
-
Hot water
-
Hydrogels (1 teaspoon of each size; small, regular, and jumbo)
-
Beakers
-
Ceramic Plates (experiments 5 and 6)
Hypothesis:
If you increase the size of the hydrogel, than the temperature around it will be lower and cooler, because the larger the hydrogel the more water can be absorbed, so the longer it will take to lose its water, means the longer it will be giving off cooler air.
Procedure:
Step 1: Hydrate the hydrogels by putting the desired number of hydrogels in a beaker full of water.
Step 2: Leave hydrogels in the water overnight so they reach full absorption .
Step 3: Drain excess liquid from hydrogels.
Step 4: Place hydrogels in beakers (experiments 1,2,3) or ceramic plates (experiments 4 and 5)
Step 5: Place thermometers in designated areas.
Step 6: Measure the temperature of the air surrounding the hydrogels over a period of time.
Variables:
Independent Variable: size of hydrogels
Dependent Variable: temperature above hydrogels
Results
We concluded from this that regular hydrogels are the most effective of the three. This will help us guide further experiments.
