Dissolving Lactase Pills

Dissolving Lactase Pills | Science Fair Projects | STEM Projects
Let's find out which brand of lactase pills dissolve the fastest! We'll measure the time it takes for each pill to dissolve in water and compare the results.


The hypothesis is that the Equate brand will dissolve faster than the Western Family, Lactase Enzyme, and Lactaid Ultra brands.

Method & Materials

You will measure 250ml of tap water, heat it to 37 degrees Celsius, pour it into a glass beaker, and put it on a magnetic stirrer. Then you will drop in a pill and start a stopwatch. When the pill dissolves, you will stop the stopwatch and record the time. You will repeat this process for each brand of pill.
You will need 5 lactase pills for each of the 4 brands, 2 magnetic stirrers, 600ml of tap water, 2 300 ml glass beakers, 1 celsius thermometer, 1 pair of heat resistant gloves, 1 thick lap apron, 1 set of goggles, and 1 microwave.


The results of the experiment showed that the Lactase Enzyme brand dissolved the fastest. This stands out because it was not the brand that was predicted in the hypothesis.

Why do this project?

This science project is interesting because it helps consumers make the best purchasing decision when it comes to lactase pills.

Also Consider

Variations to consider include testing the dissolution rate of the pills in simulated stomach acid (hydrochloric acid) and testing the dissolution rate of different brands of lactase pills.
