Answer:
Component 1: Short Review
1. To separate a mixture of sand and water, we would need a process called filtration. It involves passing the mixture through a filter to separate the solid particles (sand) from the liquid (water).
2. Magnets can be useful to separate things that are magnetic or contain magnetic materials. They can attract and separate objects such as iron or steel from other substances.
3. Between the processes of evaporation and filtering, there is a difference in the way they separate substances. Evaporation involves heating a liquid to turn it into a gas, leaving behind any dissolved substances. Filtering, on the other hand, uses a physical barrier (like a filter) to separate solid particles from a liquid or gas.
Component 2: Lesson Purpose/Intention
The purpose of Component 2 in the lesson is to teach us how to draw and use flow diagrams. Flow diagrams are important for learning because they help us visually organize information and understand processes in science. They are especially useful when answering questions in science as they provide a clear and structured way to explain concepts and demonstrate our understanding.
Component 3: Lesson Language Practice
a. Answer: Fill in the blank boxes for market A and B in the table below.
