Leave water in a dish in the sun, place a clear plastic sheet several centimeters over the dish in a tent-like shape, and have another dish on both sides of the primary dish.
The water from the primary will end up in the collection dishes because the water will evaporate and then be stopped on the sheet, and drip in to them.

What is the difference between positive and negative control in an experiment?
In an experiment, a positive control is used to show that the experiment can detect a specific response, while a negative control is used to show that the experiment does not detect a response when it should not.
Describe an experiment to show evaporation?
Place a small amount of water in a shallow dish. Measure the initial volume of water. Leave the dish in a sunny spot for a few hours and then measure the volume of water again. The difference in volume will demonstrate evaporation.
What experiment could show both air and oxygen are needed to rust iron?
One experiment could involve placing pieces of iron in two separate containers, with one container filled with just air and the other with a mixture of oxygen and another gas that cannot support oxidation. After some time, the piece of iron in the container with oxygen should show signs of rusting, while the one in the other container should not. This would demonstrate that both air (which contains multiple gases) and specifically oxygen are required for the rusting process.
What must be true of a conclusion of a controlled experiment?
The conclusion of a controlled experiment must be based on the results obtained from the experiment itself. It should directly address the research question or hypothesis posed at the beginning of the experiment. The conclusion should also highlight any patterns, trends, or relationships observed in the data collected during the experiment.
What is the negative control in the lactose experiment?
The negative control in the lactose experiment would be a sample that does not contain lactose or the enzyme needed to break down lactose. This control is used to show what would happen if no lactose were present for the enzyme to act on.
How could you design an experiment to show how a fault is formed?
How could you design an experiment to show how a fault is formed
How could you set up an experiment to show the evidence of evaporation?
# Take a bowl half full of water # Take a marker and make a mark on the bowl where the water line is. # Let the bowl of water sit out for a couple nights # You will see the water level dip below the line you drew on the side of the bowl
How could you set up an experiment to show evidence of evaporation?
you can put a drop of water on a plane of glass and then watch it evaporate or you can but a breaker of water over a busen burn or open flame and watch the water level drop and then whilst this happening, put a plane of glass above it and water will condense (become a liquid) on the glass
How did molten material show evidence of sea floor spreading?

What is the difference of a model or an experiment?
A model is to show something and it does not have a control group, like a experiment.
