A Science teacher by trade, I've also been known to be found teaching Maths and PE! However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. I am constantly thinking of new ways to engage a student with a topic and try to implement that in the design of the lessons.
This detailed and engaging lesson describes how the roles of hydrogen, iron, sodium and phosphate ions are based on their properties. The PowerPoint and accompanying worksheet have been designed to cover point 1.8 of the AQA A-level Biology specification.
The lesson begins with a made-up round of POINTLESS where students have to use their prior knowledge of topic 1 to identify four biological molecules. All four of these molecules are connected by a phosphate group and this acts to remind students that phosphate ions are a component of both DNA and ATP. Moving forwards, the rest of the lesson explores the role of hydrogen ions in pH, iron in haemoglobin and sodium in the co-transport of glucose and amino acids. The lesson has been written so that links can be made to upcoming topics including the regulation of heart rate, transport of oxygen and selective reabsorption in the nephron of the kidney.

A bundle is a package of resources grouped together to teach a particular topic, or a series of lessons, in one place.
Excellent resource with recall checks and application questions throughout. Resource allows the links between the ion and its role to be explored fully. Game format for recall checks can be adjusted but I like the pointless/competitive slides which will go down well with my students.
