* Prepare one cup with sugar water and one with fresh water.

* Take a sip of the sugar water and swish it around in your mouth for several seconds without swallowing it. Gradually, it should taste less sweet. (Dispose of the sugar water)
* Taste from the cup containing fresh water. Did the taste of the fresh water surprise you? How? Record your reaction.

The fresh water should taste sweet because of the sugar residue left in your mouth

To conduct this taste experiment and answer the question, you will need the following materials:

1. A cup of sugar water: Prepare this by dissolving sugar in water until it is sweet enough for your liking.
2. A cup of fresh water: This should be plain water without any added flavors.

Here are the steps to follow:

1. Take a sip of the sugar water: Start by taking a sip of the sugar water and swish it around in your mouth for several seconds without swallowing it. This allows the sugar molecules to come into contact with your taste buds.

2. Observe the change in taste: Gradually, you should notice that the sugar water tastes less sweet as time passes. This is because the sugar molecules in the water are binding to the sweet taste receptors on your taste buds.

3. Dispose of the sugar water: Once you have swished the sugar water around for a sufficient amount of time, you can dispose of it.

4. Taste the fresh water: Next, taste from the cup containing fresh water. Pay attention to how it tastes compared to the sugar water.

5. Record your reaction: Finally, record your reaction to the taste of the fresh water. Did it surprise you? In what way? You might find that the fresh water tastes different from what you expected. This is because your taste buds have become adapted to the sweetness of the sugar water.

The purpose of this experiment is to demonstrate the phenomenon of sensory adaptation. When your taste buds are exposed to a continuous stimulus (in this case, the sugar water), they gradually become less responsive to it. This explains why the fresh water may taste different or surprising after swishing the sugar water in your mouth.

Remember to interpret your results and observations based on your own experience, as taste perception can vary among individuals.
