Ecosystems. IGCSE Biology

The resource pack includes 5 power points, these power points include:

Structure of gas exchange system

1. Ecosystems, food chains and food webs
2. Pyramids of numbers and biomass
3. Pyramids of energy
4. Nutrient cycles
5. Nitrogen cycle

Things to include or not covered in this resource is quadrats and methods of sampling techniques.

This should cover 1-2 weeks of learning in class, in which you can also do lung dissections to reinforce content learned.
More suited for A*- B students looking for maximum marks, can be used as a basis to build lower high quality content for lower ability classes.
The power points are designed for a teacher led style of teaching, factual content and definitions are as expected by CIE examiners. Can be used for GCSE/IGCSE for variety of exam boards.

I do use resources by Beckystoke as plenary or starter activities, these are not provided in my bundle and would require them to be purchased separately. They compliment these power points.

These power points are ideal for someone who is new to teaching, they can be used alone, however, do require some additional input e.g exam questions, or additional tasks by the teacher.

The textbooks often waffle a lot, each power point should last approximately 40 minute lesson / some can be stretched over 2 x 40 minute lessons.
Power points are designed to be clear and concise, with some images to support.
