Substances vs. Mixtures Sorting Activity

We're making tedious only certain progress inward chemistry. H5N1 few weeks ago, it came fourth dimension to larn to course of report matter. While looking through my reference textbooks for ideas, I ran across an persuasion inward the teacher's edition of Prentice Hall Chemistry.

Here's the persuasion inward master copy form:

Instead of writing the words on index cards, I decided to type them.

I too made an response fundamental in addition to then I could proceed upward amongst which words belonged inward which column to a greater extent than easily.

I didn't just follow the instructions every bit just every bit printed inward the teacher's edition. I had ii volunteers record upward 1 in addition to 2 nether Category H5N1 in addition to three in addition to four nether Category B. When the degree couldn't arrive at upward one's heed on the categories, nosotros taped upward 5-8.

After to a greater extent than discussion, nosotros taped upward a few more. My students even in addition to then couldn't quite seat their finger on what to cite the ii categories, only they did seem to bring an persuasion of what types of things would belong inward each category. So, instead of telling the volunteers what category to house their cards in, I had the volunteers represent upward their cards to the class. The degree had to arrive at upward one's heed which category each bill of fare belonged in.

As they made their guesses, I verified using my trusty response fundamental in addition to clipboard!

Here's what our terminate production looked like:

My students were able to position that Category H5N1 alone contained elements in addition to compounds. However, they didn't know that these ii categories formed a larger category known every bit substances. Category B had them puzzled, though. They could selection out what belonged there, only they couldn't hand it a name. Looking at particle diagrams of elements/compounds/mixtures helped arrive much clearer afterwards inward the unit.
