I need to present to 5th graders about the difference between elements.


But the presentation needs to last 5 minutes, but I'm uncertain of how to make it last that long. Advice please?I need help with presenting to 5th graders. Advice Please?
I teach fifth grade...not science though, so i don't have a specific lesson to tell you. I would suggest presenting the information in a way that while you're talking they have something to look at. Also, if you can get them involved in doing something or moving around the room, they'll enjoy it more.





Good luck!
