I have taught secondary school science, Chemistry being my specialism, for 28 years. I have developed and used my resources in my own lessons, usually in response to a specific need or a gap in provision. I like resources that are multifaceted in the way they are used, if possible, so that they can be easily adapted to the needs of different classes, without necessarily having to alter them. I share my most frequently and successfully used here. I am now tutoring Chemistry online.

Surface area and size of the particles or parts.

£5.00
(0)
A range of concrete activites for students to explore the relationship between the size of particles or parts and the total surface area. Concept is important in explaining the function of alveoli in the lungs, villi in the intestine, particle size in reaction rate and catalysis. The concept can be explored at differentiated levels from the basic idea to deriving a quantitative relationship, depending on age, ability and context. Additional activities are included to demonstrate the functionality of moisture and thinness of the walls in the alveoli.
