This is a quick and fun way to check your student's knowledge on physical and chemical changes. There are 28 different cards that the students will put into either physical changes or chemical changes and then write their answers on the response sheet. I included a answer key so it can be self checking if you wanted. You could also post them around the room and student rotate and write their answers in the response sheet. There are colored and Black and white versions.
Middle School Chemistry: Chemical Reactions @ Education Possible When we hear the term, chemical reaction, we usually think of something exploding, don't we? But not all reactions are that noticeable. We're actually surrounded by chemical reactions every day, like rust, a match lighting, yeast in bread, and silver tarnishing. This is an extremely popular experiment, that seems quite simple, but when you add in some scientific questions, it makes it perfect for a middle school science lesson.
This middle school chemistry unit cover tons of topics from chemical reactions to mixture & solutions to conservation of energy. Includes activities, lesson plans, rubrics, teaching tips, & more! From Kristin Lee
Create an explosion in a bag to explain the the three states of matter! LIQUID - Pour 1/4 cup of warm water into a ziploc bag. Next, add 1/2 cup of vinegar to the water (food coloring optional).
