Scenario: Introduce Sand into tank and measure TDS before and after with three stages of intensity. Fake aquarium plants would help diversity the looks of this experiment.
Sand and TDS Multiple Choice Question:
Q: How does adding sand impact the amount of total dissolved solids in the tank?
INCREASE
Observe how as sand is introduced, the total dissolved solids (TDS) also goes up in proportion to how quickly the sand is spread out in the water.
DECREASE
Observe how as sand is introduced, the total dissolved solids (TDS) also goes up in proportion to how quickly the sand is spread out in the water.
NO DIFFERENCE
Observe how as sand is introduced, the total dissolved solids (TDS) also goes up in proportion to how quickly the sand is spread out in the water.
