This activity can be used in cooperative groups, whole class as a PowerPoint, or independently. It has several picture cards in which students decide whether the picture represents a chemical or physical change. There are even header cards.
Did you try to save it to a remote souce like a flash drive? It sounds like a problem with your computer and I apologize, but I really do not know how to make it save to your computer. You are the first person who has purchased this PPT and has had this problem. Please let me know if you were able to save it to a flash drive.

How many cards/examples are there? How is it used as a whole class? Is it a game?
There are 20 cards total. To use whole class you could print them on card stock, then laminate. Pass them out and have the students decide whether it's physical or chemical changes represented. It can also be used as a powerpoint, but I don't think it's as effective. You could also make several sets and have the students work in groups to sort into the correct ggroup. They should be able to identify whether it is chemical or physical and explain why (ex: the snowman melted, it's still water and hasn't changed to something new or the egg is rotten, there's an odor, maybe a color change etc) I hope this helps. Please let me know if I can help in any other way and Happy Holiday's :-)
I have been working with children since aproximately 1990. I taught 3 year-olds for about 8 years. When my daughter started kindergarten I was able to go back to school. I have taught K-5 and even 7th grade.
