Study the diagram below: In an experiment, a student filled one funnel with clay and another with humus (dirt). She poured one cup of water into the humus funnel and one cup of maple syrup into the clay funnel. She positioned the beakers to collect any liquids that was not held by the clay or humus (dirt). What did she do wrong in setting up this experiment?

• The student should not have used any liquid at all

• The student did not do anything wrong

• The student should have used the same type of liquid to pour through the humus

• The student should not have used humus

Why must scientists repeat and replicate experiments?

• To verify data and to validate the experiment

• To use up surplus materials

• Because they enjoy doing so

• To make the experiments last longer
