Surface Area to volume ratio 

Today we study the relationship between surface area and volume in organisms.  

We started with a cut-and-paste activity creating cubes with sides of 2.5 cm by 2.5 cm.  

surface area

    • In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.

      1. synonyms: outsideexterior.

        the area of an outer part or uppermost layer of something. 

        noun: surface area “the surface area of a cube”


        the amount of space that a substance or object occupies, or that is enclosed within a container. 

        “the sewer could not cope with the volume of rainwater” 

        cube = a 3 


Introduction to Life Science 

I have finally been able to sit down and create some new  images to use in my PowerPoint presentation on Introduction to Life Science for Grade 10. 

Perhaps it was the dawning of the new year,  I just felt absolutely inspired.  Here are just a few examples :
