| Why do we have to understand changes of state? Your grade 5 students will discover the answer after reading this worksheet. Changes of state are important in our everyday lives because they help us understand how materials around us can transform into different forms. For example, when we boil water to make hot chocolate, we witness a change of state from a liquid (water) to a gas (water vapor). Similarly, when we freeze water to make ice cubes, we see a change of state from a liquid to a solid. These changes of state can also help us understand how materials can be used in different ways. For instance, we can use water in its liquid state to drink or cook with, but we can also use it in its solid state (ice) to keep things cold. In addition, changes of state can also have an impact on the environment around us. For example, when water evaporates, it can form clouds that lead to rain, which is important for plants and animals to survive. So, understanding changes of state helps us to better understand the world we live in and how we can use materials in different ways to meet our needs. |
