✍️ 4. Short Answer Questions
1. Name the four main stages of the water cycle.
💡 Suggested Answer: The four main stages of the water cycle are Evaporation, Condensation, Precipitation, and Collection (or Runoff).
2. Give one example of a physical change and one example of a chemical change that you might see in a kitchen.
💡 Suggested Answer: A physical change in a kitchen could be melting an ice cube. A chemical change could be baking a cake (where new substances are formed from the ingredients) or burning toast.
🎯 5. Multiple Choice
1. Which process describes water vapor in the air cooling down and forming clouds?
2. Which of the following is an example of a solution?
3. What is the main characteristic of a chemical change?
📝 6. Open-Ended Questions
1. Explain the difference between a mixture and a solution, providing an example for each.
💡 Solution Steps:
A mixture is formed when two or more substances are combined, but each substance keeps its original properties and can often be easily separated. An example of a mixture is sand and pebbles. You can still see the individual sand grains and pebbles, and you can pick them apart.
A solution is a special type of mixture where one substance (the solute) dissolves completely into another substance (the solvent), creating a uniform mixture. The dissolved substance seems to disappear, and it's difficult to separate the parts. An example of a solution is sugar dissolved in water. The sugar crystals disappear into the water, and the whole liquid tastes sweet and looks clear.
2. Describe how the sun's energy is essential for the water cycle to operate.
💡 Solution Steps:
The sun's energy is absolutely essential for the water cycle because it provides the heat needed for evaporation. The sun warms the Earth's surface, including oceans, lakes, rivers, and even moisture in the soil and plants. This heat energy causes liquid water to change into water vapor, which is a gas. This water vapor then rises into the atmosphere, beginning the journey of the water cycle. Without the sun's energy, there would be no significant evaporation, and therefore, no water cycle as we know it.
3. Imagine you have a piece of wood. Describe two different ways you could cause a physical change to the wood and one way you could cause a chemical change.
💡 Solution Steps:
Here are ways to change a piece of wood:
<strong>Physical Changes:</strong>
1. <strong>Cutting the wood:</strong> If you saw or chop the wood, you change its shape and size, but it's still wood. The chemical composition remains the same.
2. <strong>Sanding the wood:</strong> Sanding removes small particles from the surface, making it smoother or changing its texture, but the wood itself is not transformed into a new substance.
<strong>Chemical Change:</strong>
1. <strong>Burning the wood:</strong> If you burn the wood, it undergoes a chemical change. The wood combines with oxygen and turns into ash, smoke, and gases (like carbon dioxide). These new substances cannot be turned back into wood, demonstrating a chemical transformation.
