1️⃣ Adhesion: Witness the astonishing adhesive nature of water that allows it to cling to other substances. Picture water droplets delicately clinging to the surface of a leaf or forming intricate patterns on a spider's web. This remarkable property enables water to interact with and stick to various materials, creating stunning visual displays.

2️⃣ Cohesion: Explore the inherent cohesive forces of water that bind its molecules together, creating a strong attraction between them. This cohesive nature gives water its ability to form droplets, beads, and even maintain a column of water within a narrow tube. Witness the beauty of water's cohesive forces in action as you observe the transformation of droplets and the unique shapes they create.

Lab report: station 1

Cohesion is the property of water where water molecules are attracted to each other, similar to magnets. In this experiment, we will investigate the cohesion of water and compare it to alcohol.

Based on the property of cohesion, water is expected to have a higher number of drops on the penny compared to alcohol. Water molecules are known to be highly cohesive, meaning they strongly attract and stick together. This cohesion allows water to form drops and maintain a higher surface tension. On the other hand, alcohol molecules typically have weaker cohesion, so it is likely that fewer drops of alcohol will be able to stay on the penny before overflowing.

3️⃣ Capillary Action: Prepare to be amazed by water's mysterious ability to climb against gravity through narrow spaces. Capillary action, a phenomenon driven by both adhesion and cohesion, allows water to rise in tiny tubes or spaces, defying the forces of nature. Witness this enchanting spectacle as water defies gravity and moves upward, sustaining plants and bringing life to every corner.

In Station 6 of the lab, the focus is on capillary action, which is made possible by the cohesive and adhesive properties of water. Capillary action refers to the ability of water to move against gravity in narrow spaces, such as thin straws, due to the balance between cohesive and adhesive forces.

In this experiment, we investigate capillary action, which is the upward movement of water in narrow tubes. We explore the factors influencing capillary action and its relevance to the movement of water in plants.

Experiment and Results:

Part 1: Paper Towel Bridge

We set up a beaker of blue water next to an empty beaker.
Created a paper towel bridge between the two beakers.
Observed that the water traveled along the paper towel, defying gravity.
Observation: Water moved from the beaker of blue water to the empty beaker through the paper towel bridge.

4️⃣ Surface Tension: Delve into the captivating world of water's surface tension, which creates a thin "skin" on its surface. This phenomenon gives rise to incredible sights, such as water forming droplets, insects walking on water, or even a needle floating on its surface. Explore the mesmerizing visuals that demonstrate water's surface tension and discover the secrets behind this remarkable property.

Lab report: station 2

In this experiment, we investigate the impact of detergent on the surface tension of water. We examine how detergent affects the behavior of water on a penny's surface and its implications for surface tension.

Experiment and Results:

We applied one drop of detergent on a dry penny.
Predicted the number of water drops the penny would hold after applying detergent.
Added water drops to the penny while counting them.
Detergent disrupted the surface tension, allowing water to spread easily on the penny.
The total number of drops obtained on the penny increased due to reduced surface tension.

5️⃣ Solvent Power : Water's exceptional solvent properties enable it to dissolve a wide range of substances, making it a crucial medium for chemical reactions to occur.

Lab report station: 4

The experiment in Station 4 tests water's ability to act as a universal solvent due to its high polarity. Different substances, such as salt, sugar, oil, and alcohol, are added to separate beakers of water to observe their dissolution. The experiment aims to determine whether each substance is polar, non-polar, or ionic when mixed with water. The results and observations help understand water's effectiveness as a solvent and its ability to dissolve a wide range of substances.

In the experiment, we investigated the ability of water to act as a universal solvent by attempting to dissolve various substances in liquid water. The substances used were salt (NaCl), sugar, vegetable oil, and colored alcohol (ethanol).

We conducted the experiment by measuring 50 ml of water into each labeled beaker. We then added a spoonful of each substance to the corresponding beaker and stirred or swirled to encourage dissolution.

Water + salt (NaCl): Salt likely dissolved completely in water due to its ionic nature.
Water + sugar: Sugar likely dissolved completely in water due to its polar nature.
Water + oil: Oil likely did not dissolve completely in water due to its non-polar nature.
Water + alcohol (ethanol): Ethanol likely dissolved completely in water due to its polar nature.

6️⃣Density Anomaly: Prepare to be astonished as you witness a peculiar behavior of water. Unlike most substances, water exhibits an anomaly in its density! You'll be amazed to see ice, a solid form of water, floating on its liquid counterpart. This extraordinary phenomenon plays a vital role in preserving aquatic ecosystems and protecting life beneath the surface.

Lab report:station 5

In Station 5 of the lab, the focus is on the unique density property of water. Water is one of the few substances that become less dense as a solid (ice) than as a liquid. This is due to the hydrogen bonding between water molecules.

Water is known to be dense because of its molecular structure and hydrogen bonding. Water molecules are held together by hydrogen bonds, which result in a relatively high density. This density allows water to have various important properties, such as buoyancy and thermal regulation.

7️⃣High Specific Heat: Immerse yourself in the fascinating realm of water's high specific heat capacity, which allows it to absorb and store large amounts of heat energy without significant temperature changes. This property acts as a natural temperature regulator, helping to stabilize climates and maintain a comfortable environment for life to flourish.

Lab report: station 3

In this experiment, we aim to investigate the heat capacity of different substances, with a focus on water. Heat capacity refers to the amount of heat energy required to raise the temperature of a substance. By comparing the heat capacity of water to another substance, we can further understand the unique properties of water and its significance for various applications.

Experiment and Results:

We conducted an experiment using water and another substance (e.g., ethanol) at room temperature.
A drop of water was placed in a designated area, and a drop of the other substance was placed in a separate area.
We recorded the time it took for each drop to completely evaporate.

Based on water's known high heat capacity, it is likely that water took longer to evaporate compared to the other substance, indicating that water has a higher heat capacity.

Water's remarkable properties not only shape our planet but also sustain all life forms. It's a source of endless fascination and an essential part of our existence!
