Lab - Separating a mixture, homogeneous mixture, heterogeneous mixture, physical properties, chemical properties
This lab activity is best used in the beginning of the school year or when classification of matter is discussed. Your students will be able to identify homogeneous and heterogeneous mixtures as well as physical properties of a substance. Setup is very easy with my materials sheet - see the product preview for details. Perfect for middle school science!
Learning objectives: Your students will be able to…
•Identify heterogeneous and homogeneous mixtures.
•Explain what occurs to a substance's chemical and physical properties when placed in a mixture.
Materials your students will need:
•iron filings (Fe)
•sodium chloride (NaCl)
This lab activity includes:
•4-Page lab activity
•8 Pre/Post-lab questions
•Teacher’s prep guide
Your students will love this lab because it's fun and you'll love it because it's easy on the prep time!
