混合物分离
Description
Use knowledge of solids, liquids, and gases to decide how mixtures might be separated through filtering, sieving, and evaporating
Mastery Evidence
- Choose the correct separation method for a given mixture (sieving for large particles, filtering for small, evaporating for dissolved)
- Describe a multi-step separation plan for a complex mixture like sand, salt, and water
- Explain why each method works based on the properties of the materials
Assessment Prompt
If your child has a mixture of sand, salt, and water, can they figure out a step-by-step plan to separate all three using a sieve, filter, and evaporation?
