I LOVED presenting this lesson, and the students did too!
The preview shows the slides in this presentation. However, in order for my file size to be small enough, I had to delete a couple of the photo sides. Some of these can be seen in the thumbnails. Your download will include the Keynote, which will be editable, and a Quicktime version that will allow any computer to use this similar to a presentation. You will be able to click to advance through the slides and animation. Also included is a worksheet that I have used to have students complete in groups to hunt for minerals in cereal. I ask students to bring in empty cereal boxes about two weeks before beginning. I cut out the front, with nutritional side panel, and keep these to amass my collection over the years.
I put a lot of time into my Keynote presentations to introduce concepts. I make sure that they are engaging, and have animations to present information. This is one of many that I can no longer use due to my current teaching assignment.
I used this in 3rd grade, but it can be used for 4-6th grades too. It is a great lesson to use in conjunction with geology. It starts out with the difference between minerals and rocks. Goes into the fascinating look at diamond mining, and then goes in depth about the various minerals in food. This usually is done over a 2-3 day period.
If you enjoy this, please follow me as I'm planning to slowly upload many more Keynotes soon.
