National Day Calendar Classroom - October 22 -28, 2017


Science and fun come together when National Greasy Food Day enters the week on October 25.  While celebrating foods such as French fries and potato chips should just be an occasional matter, we can take the opportunity to learn a little more about these foods.

To complete this experiment in your classroom, you will need squares of brown paper and a variety of foods in small pieces.  Include foods that have a high grease content to those that have none at all.

Here we have included six different kinds.  Alternatively, you can use this image to create a matching quiz.
