These matter and change lab station activities will review and reinforce the topics and concepts taught in your unit on matter. Nothing gets kids more excited about science than doing science experiments. This set of 4 mini-labs includes experiments that are fun, engaging, and thought provoking. These experiments will reinforce the concepts you have taught in class as well as develop good critical thinking and problem solving skills.
The four lab stations cover density, proper lab techniques, mixtures, and chromatography. Students will learn how to separate the components of a mixture, and will learn that solids and liquids are not as easily defined as they thought. Students will identify that chemical changes have occurred when they observe a color change, the formation of a precipitate, and the release of gases.
PLEASE NOTE: This lab station activity is included in my money-saving bundle: Matter and Change Unit Bundle. Click this link to view the bundle.
The four lab stations can easily be completed in 2 class periods. Each station is a mini-lab that can be used as a stand-alone activity. You can do one station or do them all.
Purpose of the labs:
1. To determine the density of pennies minted before 1982 and after 1982.
2. To use paper chromatography as a method of separating the components of a mixture.
3. To determine if a strange substance is a solid or a liquid.
4. To observe several chemical changes.
Your download will contain 5 pages of editable handouts that are ready to be copied and passed out to your students. Included in the student handouts: Title, purpose, safety precautions, procedure, data tables, and analysis questions.
You will also receive a 7-page document for the teacher. This includes complete materials list, instructions for preparing solutions, suggestions for making the lab run smoothly, and answers to all questions.
You will receive both a Word document as well as a pdf of the worksheets.
